Embitterment has been described as the emotion generated in the aftermath of an event experienced as unjust and unfair. Although embitterment is most commonly presented in the work context, research on workplace embitterment has remained scarce due to the fact that the concept of embitterment is rather new. This thesis aimed to shed some light on the prevalence of this emotion, its developmental context, outcomes and ways of treating it. Results from this thesis suggests that breaches in organisational justice, can trigger feelings of workplace embitterment which can impact negatively employees’ ability to psychologically unwind from work, as well as their work engagement and job satisfaction levels. The unfolding of further features of workplace embitterment and the development of interventions to improve this feeling seems a worthwhile future endeavour.

While cyberbullying in education is a widely studied topic, research into workplace cyberbullying is less well represented in the literature.  There are a number of approaches taken in the literature to defining the topic which results in a lack of an agreed definition on which to base future research.  Using a qualitative approach involving in-depth face to face interviews with fifteen participants this study aimed to produce a definition of workplace cyberbullying grounded in the literature and supported by real world experience.  Additionally, a comparison of the perceptions and the prevalence of workplace cyberbullying between the public and private sectors was undertaken.  The definition of workplace cyberbullying produced was: Any act, intended to cause harm or perceived as harmful in the workplace that is delivered through digital means.  The results of this study indicate that there is little difference between the two sectors regarding the perceptions of what constitutes cyberbullying in the workplace, with email misuse being the single most reported avenue for workplace cyberbullying.  The implications of the study are that email misuse is a common cause of workplace cyberbullying in the workplace and given the high number of participants in the current study reporting experiencing workplace cyberbullying further research is recommended to quantify the extent of the issue.

Over the last decade, the nature of bullying has changed dramatically, moving from traditional, face to face to via communication technologies. The associated bullying behaviours and technologies is collectively known as ‘cyberbullying’. Cyberbullying is an increasing problem which results in negative outcomes for all involved. For victims, it is ubiquitous; there is no escape. Cyberbullying, has been directly and indirectly linked to an increased risk of suicide for both victims and bullies. It is therefore vital to explore what children, parents and teachers interpret as cyberbullying and how to design effective interventions to reduce cyberbullying and/or develop resilience and coping strategies. To date, research on cyberbullying has focussed on children in their teens. However, little is known about the perceptions of younger children particularly at the key transitions point from primary to secondary school. At this age, self-esteem decreases and peer support and influence become very important in determining behaviour. Technology use increases around this age and parental monitoring decreases. This thesis uses multiple methods to fully explore similarities and differences in perceptions and experiences between children before (aged 10-11 years) and after (aged 12-15 years) this transition and develops a behaviour change intervention to promote more positive behaviour online, increase resilience and self-efficacy. This thesis aims to develop ways for children to overcome adversity by developing their problem-solving skills and increasing their confidence levels to deal with a negative situation through building their cyberbullying resilience. Cyberbullying resilience can be strengthened through external factors such as a supportive environment, strong peer support and a sense of belonging and internal factors including high self-esteem, self-control and self-efficacy (Bozak (2013) as cited in Hinduja and Patchin (2017)). Initial findings suggested that cyberbullying is predominantly a female behaviour and that victims and bystanders are reluctant to seek adult intervention unless the situation is considered to be so extreme that they can no longer cope. Primary girls were found to be more likely to report a cyberbullying incident than secondary, even though there was no difference in their perception of the severity of the incident. This thesis adds to the literature by highlighting children, parents and teachers’ understandings and expectations around reporting and what these are. This thesis identifies age differences in relation to cyberbullying perceptions and reporting channels and presents a behaviour change intervention which increased self-efficacy and resilience levels. It is also applies a unique intervention approach by introducing implementation intentions with the intention to increase kind online behaviour in addition to building self-efficacy, self-esteem and cyberbullying resilience so that children have skills and strategies in place to deal with adversity online should the time come.

This investigation seeks to evaluate the impact on individuals, and society, of Self-Generated Images (SGI’s) in online pornography. It presents an inquiry into the extent, and modes, of SGI use among a large sample of adult internet users. This form the initial platform for a theoretical analysis of the rapidly emerging topic, alongside an empirical investigation into how SGI’s are used, and criminally abused. A mixed research method strategy was consequently adopted, employing a quantitative anonymous online survey (Stage 1), qualitative face-to-face interviews with serving Metropolitan Police Service officers in the SOECA unit (Stage 2), and qualitative Skype interviews with active SGI users (Stage 3). The thesis is divided into three main sections. Firstly, in chapters one-to-four, the context for this study into SGI’s is explained, including the specific UK statute laws regarding licit and illicit pornographic images. Commonly used pornographic terminologies are defined. Furthermore, existent research on the topic of SGI’s/online pornography is scrutinized, and several theoretical issues are given a discourse in relation to SGI’s. An analysis of the free speech/online pornography debate is included, together with an examination of the criminal abuse of SGI’s. The second part, chapter five, provides a rationale for the adoption of a mixed research methods strategy in pursuing the aims of this study. Many methodological issues regarding the three stages of the primary fieldwork are addressed; these include: ontology, epistemology, research paradigms and axiology, ethical underpinnings, practical considerations, and the strengths and limitations of methods chosen. In the third section, chapters six-to-eight, the study’s key findings include a taxonomy of the six main types of SGI. Passive SGI viewing is very pervasive, particularly among the key demographic groups of younger adults, Lesbian Gay Bisexual Transgender (LGBT) and males, and may be becoming the norm. Free PornTube websites are predominately used; but also, increasingly, social network sites (SNS’s) and messaging/image sharing apps. Most adults use SGI’s safely for sexual stimulation; however, some use them for educational and humorous purposes. For a minority of active creators of SGI’s, disastrous personal consequences can result because of subsequent criminal abuse, including cyber-bullying/trolling, sextortion, etc. Gay and bisexual men have highly accelerated rates of SGI use on hooking-up sites, often leading to hazardous risk taking. Children face grave dangers from making and sharing sexualised SGI’s as online child sexual abuse (CSA), grooming and sextortion, etc. may transpire. In the UK’s schools, Personal, Social and Health Education (PSHE), and Sex and Relationships Education (SRE), are in a parlous state regarding the issues and dangers of SGI’s. Finally, this inquiry provides some original insights into the areas of applying and generating theories, using mixed research methods, and the empirical findings uncovered.

This thesis presents an examination of the historical developments of vicarious liability law in the English legal system over the past 200 years. The developments considered date from the principles laid down in Joel v Morison [1834] EWHC KB J39 to the most recent case of Bellman v Northampton Recruitment Ltd [2017] IRLR 124. The various tests for employment status and the course of employment are discussed, with specific analysis into why the tests have changed and developed. Case law and academic criticism is presented to emphasise how the changes have had a positive or negative impact on the clarity and fairness of the area of law.

This thesis explores the scale of bullying in Taiwanese schools and the impact of school anti-bullying policies. Critical realism is used in this policy-related research to argue against current empirical bullying research mainstream and how it may be possible to conduct scientific policy research in Taiwan. The thesis is divided into two parts, covering the literature review and methodology (four chapters in part one) and analysis of the case study in Taiwan (three chapters in part two). This research endeavours to link critical realism with empirical research to deepen our understanding of the school anti-bullying policy structure in Taiwan. The thesis begins with the exploration of the conceptualisation and development of bullying research in Chapter 2 whose main purpose is to capture the definition of bullying and the prevalence of school bullying in different countries and then illustrate the main research areas and the international trend of bullying research. Following Chapter 2, bullying-related theories and approaches to bullying research are highlighted in Chapter 3 and policy process theories and school anti-bullying policies are touched on in Chapter 4 in term of policy agenda setting, policy formulation and policy implementation consideration. A crucial role is played by Chapter 5 which focuses on the philosophical discussion of critical social research (ontology, epistemology and methodology) with reference to the appropriate use of practical methods and related ethical issues. This chapter sets out to explain how critical realism could function in this research to bridge the gap between the literature review and the case study research. In part two, three chapters discuss the formation of school anti-bullying policy in Taiwan. Chapter 6, which is an historical inquiry, illuminates the trajectory of school regulation policies with regard to the democratic transformation of a political system since 1945 in Taiwan. After the historical discussion, light is shed on empirical inquiry into school anti-bullying policy in Chapter 7, which analyses different debates over school anti-bullying policy and power struggles between four different policy stakeholders. Most importantly, Chapter 8 attempts to theorise the ‘generative mechanism’ behind the policy making process and the inferential logic of knowledge production is also considered at the end of this chapter. In addition, reflection on the generative mechanism and collective agency of community and professional groups in policy making are also involved. The concluding chapter reflects on the use of theories, methodology and the research findings in answer to the research questions and elaborates on the compatibility of critical realism, the critical qualitative case study and school anti-bullying policy research in Taiwan. To be reflexive this chapter finishes by looking at further research directions for policy making and practice between political governance, policy research and school practice.

Burnout in human services has become a widely researched psychological concept over the last 40 years (Shaufeli, Leiter & Maslach, 2009). Negative outcomes of clinician burnout in mental health services is well documented, however less research has focused on the specific burnout subsection of depersonalisation (Maslach, 1998). A mixed methodology was used which aimed to examine predictors of depersonalisation among qualified clinicians employed in NHS mental health services, as well as an exploration of experiences of resilience and burnout. A total of 261 Mental Health Nurses, Clinical Psychologists and Social Workers employed in NHS mental health services completed an online survey and open-ended qualitative
questions. Multiple regression analysis suggested five significant predictors of depersonalisation; clinicians’ specialties, years of experience post-qualification, exposure to physical abuse, emotional exhaustion and low ratings of personal achievement. No significant differences of depersonalisation were reported among different professions. Thematic Analysis of responses to open-ended questions suggested that a ‘love of the job’ or desire to ‘help service users’ supported resilience. Job stressors such as exposure to physical abuse or bullying were reported as detrimental to resilience. Implications of maintaining compassionate and effective client care were discussed as well as limitations and areas of future research.

Subclinical psychotic experiences (SPEs) are non-clinical, transient and benign but can become severe along the psychosis continuum pathways. The SPEs pathway is precipitated by bio-psychosocial underpinnings (stress, peer and family functioning, bullying, depression and anxiety), fundamentally during adolescence. Therefore, this research aimed to understand the association between stress and SPEs, how this association is moderated by peer and family functioning, possible subtypes of SPEs in this population and their prevalence and association with bullying. Common psychopathologies in adolescence, such as depression and anxiety, were also investigated in Britain and Trinidad. The research found elevated levels of stress to be associated with higher levels of SPEs and bullying was associated with specific types of SPEs, particularly, perceptual abnormalities-delusional ideas (PADI), persecutory ideation (PI) and magical thinking (MT). Adolescents with high levels of depression and anxiety are at an increased risk of decline in peer relations and reduce academic achievement both in Trinidad and Britain. The findings of this research informs that stress and bullying are possible risk factors in the onset of SPEs and the dysfunctional impact of depression and anxiety symptoms on peer relations and school life. This signals the need to reconstitute the cognitive and behavioural aspects of adolescence by early intervention of cognitive and behavioural therapy.

This thesis investigates the experiences of young people who identify as lesbian, gay, bisexual, transgender and who are questioning their sexuality (LGBTQ) on the Internet. Specifically, the project explores how LGBTQ young people use the Internet, how they communicate online, the impact that the Internet has on their life and how they stay safe online. Despite the Internet being an ever-growing aspect of people’s lives and the potential opportunities that it presents for marginalised groups such as LGBTQ young people, there have been a relatively small number of qualitative studies in the area. Methodology: As there has been limited research regarding LGBTQ young people’s use of the Internet, a systematic review of qualitative studies exploring the experiences and views of cyberbullying by children and adolescents in the general population was conducted using Framework Synthesis. Subsequently, an empirical study was completed which involved conducting a secondary analysis, using Framework Analysis methodology, of data collected from focus groups with LGBTQ young people regarding their Internet use. In total, five focus groups were held with forty-one LGBTQ young people recruited across four European countries. Results: A total of eighteen studies were included in the qualitative synthesis exploring children and adolescents’ cyberbullying experiences. Although there was some variation in the quality of the studies, there was clear support for four main themes: Online vs. Traditional Bullying Environment, Risk Factors, Victim’s Experience and Preventative Measures. These themes highlighted both the potential causative factors of cyberbullying as well as how the victim experiences different aspects of the incident such as their initial understanding of the event to the long-term impact of cyberbullying. A number of preventative measures were also suggested, including the need for adults to increase their understanding of technology and cyberbullying in order to enable them to be a viable source of help. Within the empirical study, four main themes emerged from the data: Digital World as Part of Daily Life, In Control of Their Online World, Seeking Connection and Navigating Risk. The latter three main themes also consisted of a number of subthemes. The results indicate that participants have embraced the Internet into their everyday lives and that the LGBTQ population reaps specific benefits as the Internet allows them to overcome or compensate for barriers faced within their offline lives. Participants also reported the need to navigate many risks online, however interestingly they appeared confident in doing so and discussed the variety of ways in which they achieve this. Discussion: The results of the qualitative synthesis provided tentative support for two different theoretical models of cyberbullying, indicating that both an individual process model and an ecological system model are mutually useful ways of understanding this phenomenon. Clinical implications spanned both individual and systemic measures that could be taken to reduce the likelihood of cyberbullying occurring. However, it is also clear that further research, in particular qualitative research, is required to continue to develop our understanding of this topic as a whole. The findings from the empirical project suggest that LGBTQ young people must balance the opportunities provided by the Internet whilst also managing the risks that it poses. The importance of retaining the empowerment for young people on the Internet was clear, especially for young LGBTQ people who may use the Internet as an alternative way of meeting their needs and engaging in developmental tasks such as sexual identity development. However, there is also a need to ensure that these young people are safe online and therefore interventions such as parental education and the development of age appropriate resources are required to promote both empowerment and safety for this population.

Immigration to Ireland in the late 20th and early 21st century has transformed Irish society from being a largely mono-cultural to a more intercultural society. This study is concerned with the experience of migrant students in a second level school. It explores the experiences of a small number of migrant students who completed five years of second level education in a provincial Irish town. The students came from a range of countries in Eastern Europe and Africa. This is a one-school insider case study where the principal is the researcher using qualitative interviews with students and staff to build a picture of intercultural education with its strengths, weaknesses and suggestions for improvement. In-depth qualitative interviews were conducted with students in the year or two after they completed school. Teachers’ experiences were also analysed using questionnaires and interviews. The portrait that emerges is that of a school in transition with a vibrant and complex intercultural student population. Themes emerging as significant from the research include the school curriculum, bullying and racism, relationships with teachers, the role of parents, the experience of socialisation and schooling and pedagogical responses. These complex issues are discussed in light of student experiences, teacher comments and insights from literature. Recommendations are made for a more inclusive curriculum, for celebrating the resource that is an intercultural classroom, for a pedagogy of cooperative learning, peer education and action research by students and teachers.

The current research sought to develop the Implicit Relational Assessment Procedure (IRAP) as a measure of bullying attitudes amongst Secondary School and University Students in South East Ireland. The research assessed whether IRAP performance differed between University and Secondary School Students; and investigated the impact of picture versus word stimuli on IRAP performance. It also examined whether an educational intervention video affected participant responding on implicit measures by presenting the IRAP at pre and post-intervention. Explicit measures were presented at pre-intervention only and compared across studies. Implicit measures were presented at pre and post-intervention and compared across groups, gender, and IRAP stimuli (words versus pictures). In Study 1, 30 University Students and 30 Secondary School Students were exposed to (i) a word-based IRAP designed to assess attitudes towards toxic (e.g. Just go die/Rot in hell) and innocuous phrases (Go on ya fool/Don’t be daft) pertaining to bullying; (ii) explicit measures including the Bullying Prevalence Questionnaire (BPQ), the Revised Pro-Victim Scale (RPV-S), the Bullying Attitudes Questionnaire Modified (BAQ-MM) and the Cyberbullying Survey (CS) and (iii) an educational intervention video about the negative and lasting effects of bullying. IRAP trial-type analysis for Study 1 revealed statistically significant effects on the Toxic- Abusive and Innocuous-Harmless trial-types. Results revealed no statistically significant differences between data for groups, gender, or between pre and post-intervention responses on the IRAP. Using Pearson’s product-moment correlation coefficient, statistically significant correlations were found between the Pro-Social subscale of the BPQ and Toxic-Harmless and Innocuous-Abusive IRAP trial types. In Study 2, 30 University Students were exposed to a picture-based IRAP with images pertaining to cyberbullying and the same intervention and explicit measures as in Study 1. Again, participants were exposed to the explicit measures at pre-intervention, and to the IRAP at pre and post-intervention. Trial-type analysis for Study 2 revealed statistically significant effects on the Toxic-Abusive and Innocuous-Harmless trialtypes. Results revealed no statistically significant differences between participants’ pre and post-intervention scores on the IRAP or explicit measures; and no correlations between implicit and explicit measures. Further analysis using a 2x2x4 mixed repeated measures ANOVA found no statistically significant differences between University Students’ responses on a word-based IRAP in Study 1 versus a picture-based IRAP in Study 2. Overall, participant responding on the IRAP showed a statistically significant effect for the Toxic- Abusive and Innocuous-Harmless trial-types. Findings are discussed with reference to the research literature.

Tackling bullying within the healthcare profession is a major priority considering the costs and risks associated with it, and a full understanding of what behaviours constitute bullying is crucial (Allen, 2015). This mixed-methods study’s QUAL/Quant aims were, firstly, to establish what ALT staff considered to be their experiences of bullying (QUAL) and, secondly, to consider the prevalence of negative acts and their potential relationships to levels of reported depression (Hypothesis 1), stress (Hypothesis 2) and anxiety (Hypothesis 3) (Quant). A pragmatic epistemological framework was utilised for this study with a qualitative focus. Employees from five divisions of ALT were invited to participate in this study, and 303 (response rate 27.5%) took part in the quantitative questionnaire-based study. Eight participants who had described experiences of being bullied were interviewed qualitatively. Prevalent negative behaviours, as reported were: being exposed to an unmanageable workload, having your opinions and views ignored, excessive monitoring of work, being ordered to do work below your level of competence, and being ignored or facing a hostile reaction when you approach. All three hypotheses were strongly supported, in that there was a significant positive relationship between reported experiences of negative acts and levels of depression, anxiety and stress. A constructivist grounded theory approach was adopted for the analysis of the qualitative data. The findings suggested that the experience of bullying was far more complex than the reporting of negative acts and included a stealth-like nature prior to individuals recognising a bullying event. The integration of both methods during the analysis enabled a more thorough exploration of the experience of bullying behaviours than either a qualitative or quantitative approach would have achieved in isolation.

This body of work examines lived experiences of LGBT people within three sub-themes: sex and relationships education (SRE) and sexual health; homophobic, biphobic and transphobic (HBT) bullying; understandings and experiences of LGBT ‘community’.  I have identified a persistent invisibility of LGBT identities in school-based SRE and NHS healthcare provision, and argue that heteronormativity and heterosexism impact on sexual decision-making and sexual wellbeing. In particular, they foster fears about health services, specific concerns about confidentiality and/or disclosure, and fears about judgement or discrimination during health-related encounters.  In work in school and youth work settings I have linked curriculum invisibility to experiences of homophobia, suggesting that there is more at play than individual experiences of ‘bullying’. I have highlighted the complexity of language use related to homophobia and bullying, and demonstrated that some school responses can (appear to) ‘abnormalise’ LGBT identities, for instance in referrals to counselling that young LGBT people can interpret as apportioning ‘blame’. I have also pointed to tensions between governmental efforts to address HBT bullying and, until recently, their lack of support for school-based SRE.  In exploring constructions of LGBT ‘community’, I have demonstrated the complexity of experiences, and argued that use of the (singular) term ‘LGBT community’ risks minimising or misunderstanding such diversity, which has implications for service planning and provision.  Across my work, I stress the importance of adopting a sociological approach to what are often psychologised subjects, demonstrated in my illustrations of people’s ongoing (LGBT) identity management. In doing so, I show how legislative developments do not always lead to improved experiences for LGBT people. However, I seek to influence policy and practice in a way that does not over-state LGBT people’s perceived ‘vulnerabilities’ or ‘at riskness’, and that does not portray (particularly young) LGBT people as inherent ‘victims’ in need of ‘support’.

Sibling relationships have a great impact on children’s social and psychological development. This thesis provides an all-encompassing examination of the precursors and outcomes of sibling bullying through three quantitative studies: the first study, a meta-analysis, provides a foundational schema of the factors associated with sibling conflicts; the second study, a short-term longitudinal study, examines the individual and proximal precursors of sibling bullying and its short-term outcomes (one and two years later); the third study, a long-term longitudinal study, examines the distal precursors of sibling bullying and its long-term outcomes (five years later). The first study assessed the strongest effect sizes associated with sibling conflicts. It examined the link between parent-child relationships, familial factors and sibling conflicts. Studies were identified through a systematic search, coded, and selected based on criteria relevant for this study resulting in 60 studies (178 effect sizes), which in total involved 43,270 participating children and adolescents. Studies were categorised as proximal and distal factors. Those involved in sibling conflicts were significantly less likely to have authoritative, and warm and affectionate parents, and less likely to come from families with affluent socioeconomic-status, positive family climate and good marital quality. Conversely, more sibling conflicts were significantly related to abusive and neglectful parents, and parent-child conflicts; and more likely to come from families with poor mental health, low SES, adverse family atmosphere and parental conflict. The factors were moderated by assessment methods, study design, direction and form conflict, gender constellation, and continent. This study served as a building block for the two following studies, as it highlighted key factors to focus on in further assessing the precursors and outcomes of sibling bullying. The second study, which was based on the Edinburgh Study of Youth Transition and Crime (ESYTC, 2014) found that parenting factors were crucial to sibling bullying. Parental involvement, parent-child conflict and parent-child leisure time were precursors and outcomes of sibling bullying, so that more parental involvement and parent-child leisure time were associated with less sibling bullying perpetration and victimisation. Further, sibling bullying perpetration and sibling victimisation were precursors of peer bullying perpetration and victimisation one and two years later. However, the strength of the association declined over the course of two years. Impulsive behaviour and social alienation seem to be fundamental influencing factors in the development of sibling bullying and sibling victimisation, respectively. Additionally, children who were involved in peer bullying were more likely to have been involved in sibling bullying, compared to peer neutrals one and two years later. The third study, which was based on the Avon Longitudinal Study of Parents and Children (ALSPAC, Boyd et al., 2012) found that maternal somaticism was the strongest predictor of sibling bullying. Further, the strongest predictor of sibling victimisation was partner-to-mother verbal violence. Symptoms of depression at 16.5 years of age was the strongest outcome of sibling bullying perpetration and victimisation at 12.5 years of age. Children who were peer bully-victims when they were 17.5 years old were more likely to have been sibling pure bullies and sibling bully-victims, compared to children who were peer neutrals. The results suggest that familial factors significantly influence the quality of sibling relationships. Additionally, the findings show that sibling bullying is related to peer bullying, so that children mirror bullying behaviours across social contexts (i.e. family environment and school environment). The findings of this thesis are important for clinical practitioners, social workers, parents and schools. Based on these findings practitioners could tailor family and parenting intervention programs that prevent siblings from establishing conflictual relationships with one another. Particularly, it is suggested that bullying intervention programs should integrate three aspects: family members should play an integrated and active role in their plans to reduce bullying and victimisation; bullying intervention and prevention studies should commence at preschool ages; positive family climate should actively be nurtured, in addition to lowering hostility.

Psychotic phenomena are prevalent in non-clinical populations, with a continuum existing between psychotic-like experiences (PLEs) and incidence of clinical relevance. Phenomena-associated distress often demarcates a threshold whereby individuals seek help, and experiential risk factors are consistent at both ends of the continuum. Increased exposure to stressors may predict the transition from transient, to persistent and impairing psychotic-like symptoms. PLE-specific trajectories have been noted in the literature, with childhood bullying victimisation mooted to predict the development of paranoid thinking; paranoid thinking underlies some expressive violence. Whilst bullying victimisation is a cause for concern in itself, the cognitive and behavioural consequences for victims are potentially significant. Paranoid individuals can incorrectly appraise threat in neutral social situations, and employ maladaptive safety behaviours to reduce perceived danger. Such misperception of social events, and behavioural responses, could result in aggressive or violent actions towards others. The current thesis examines this topic.

Bullying is a social phenomenon that impacts girls and boys inside and outside of school at both primary and secondary school age and is recognised as a social problem both by academic researchers and in the ‘real world’ by the media and by anti-bullying charities. Although bullying is a widely used concept there is no universal definition. Research on bullying has been conducted over the past four decades looking at various aspects from prevalence and severity to coping strategies and effectiveness of interventions. Studies have also considered specific types of bullying and sex differences but these studies do not consider the full variety of types of bullying boys and girls use or which ones are the most upsetting to experience. Most of the studies on girls’ bullying have been conducted in secondary schools; less attention has been given to tweenage girls. This research redressed this imbalance. It began from the position that it is important for adults to listen to tweenage girls’ views as they may have different understandings of bullying compared to adults and this may have policy implications. It assumed that girls were experts on bullying that happened to girls their age in their school. Weekly research lunch club sessions were used with 32 tweenage girl research advisers/assistants from three primary schools. Together we listened to tweenage girls’ views of bullying broadly through developing and administering questionnaires, conducting group interviews and designing anti-bullying resources to be used in their schools. In addition, I conducted one-off focus groups with 11 teenage girls as a comparison to consider age differences in girls’ views. I argue that this research revealed that both girls’ bullying and using pupil research to engage with tweenage girls’ views on this topic was messy and complex. While relational aggression between girls was reported to be most prevalent and severe, focusing on this alone does not reflect the full extent of the behaviours used in girls’ bullying. Both the tweenage and teenage girls’ views on bullying, coping strategies and anti-bullying interventions were similar and were only subtly different in the detail. The research decisions were influenced in an ongoing process by the wants and expectations of the girls, the schools and the researcher and changed through the prolonged interactions during the research. I also argue that ethical practice was an ongoing process and using pupil research created further ethical dilemmas. Although pupil research with tweenage girls on girls’ bullying was challenging and messy, this research gives an example of how it is a viable, successful way to engage with pupils on this sensitive topic. The use of girls’ free time at lunchtimes showed how pupil research positioned as an extra-curricular activity enabled marginalised voices to be heard and was beneficial for the girls, the schools and the researcher involved. This research suggests ways in which school based anti-bullying policies and practices might be more nuanced to take account of the variety of experiences, understandings and preferences for intervention that exist if they engaged in pupil research. There has been little discussion of the issues of the messiness of research and the ongoing nature of ethical practice in either the pupil research literature or methods texts generally for researchers to refer to. I suggest that it would be useful for others to share their messy experiences of pupil research and the ongoing ethical issues they encounter to enable future researchers to be somewhat prepared and confident in responding to the challenges they may face in their own research.

The overarching aim of the thesis was to identify and explore a behavioural typology of the use of reactive and proactive aggression in a sample of 9-14 year-old English children and adolescents. To date, few studies have employed a person centred approach to investigate behavioural patterns of the use of both reactive and proactive aggression. Of these only two have investigated the behaviour of community, rather than specialised or clinical participant samples (Crapanzano, Frick and Terranova 2010; Mayberry and Espelage 2007). However, these two studies employed methods which raise questions regarding the reliability and/or generalisability of the results obtained. For example, neither study asked participants whether they had actually engaged in the behaviours of interest; rather they asked children to report on how likely they felt they were to react in the same way as described in a list of aggressive scenarios presented to them. As such the studies did not actually record engagement in aggressive behaviour, rather the participants’ perceived likelihood that they would behave in a certain way. Furthermore, neither study was conducted in the UK, leading to questions of generalisability between participant samples. Both research and school policy in England and Wales has focused on exploring the use of proactive forms of aggression (including bullying) in schools, and reactive aggression has to date been neglected. However, it is essential that we identify the prevalence and patterns of the use of both reactive and proactive forms of aggression as both are prevalent in schools and place children and adolescents at risk of harm. Employing a mixed methodological approach, a two-phased data collection procedure was followed to identify and explore a behavioural typology of the use of reactive and proactive aggression and differences in associated demographic, behavioural and socio-cognitive risk factors between the behavioural groups identified. In Phase 1, focus groups were conducted with 57 (20 males, 37 females) children and adolescents aged 9 – 18 years, in order to understand how they define terminology utilised across the research literature to describe acts of negative interpersonal behaviour. Across three data collection sites participants reported consistent definitions of the terms provided to them and differentiated between the terms aggression, violence and bullying. Social representations of the reasons they believed people engaged and avoided engaging in interpersonal aggression also emerged from their talk. These related to the role of taking the perspective, or empathising with others and the perception of a level of justification for certain types of behaviour, enacted under certain conditions. In Phase 2 a survey design was used to collect both qualitative and quantitative data from 658 children and adolescents aged 9-14 years (302 males, 356 females). The aim of Phase 2 was to identify a behavioural typology of the use of reactive and proactive aggression based on self-report data collected using a modified version of the Reactive-Proactive Aggression Questionnaire (RPAQ; Raine et al 2006). Once the behavioural subtypes were identified, associations between subtype and, involvement in bullying relationships, demographic (age and gender) and social-cognitive characteristics (empathy, perceived acceptance of behaviour and social representations of why people become involved in negative interpersonal interactions) were examined. Cluster analysis of the RPAQ data identified three distinct behavioural groups characterised by lower than the sample median use of both types of behaviour (Low Aggression: characterising 57.1% of the sample), Moderate-high reactive and Low-moderate proactive aggression (characterising 34.4% of the sample), and finally a group indicating frequent use of both reactive and proactive aggression (High Aggression: characterising 8.5% of the sample). The only age and gender related differences within the clusters were found in the low frequency aggression cluster. Specifically, there were a greater proportion of females compared to males in this cluster. The only age related difference found was a greater percentage of primary school children compared to 13-14 year olds in the Low aggression cluster. Group membership was found to be associated with self-reported bullying as measured by the Peer Victimization and Bullying Scale (Mynard and Joseph 2000). The High frequency aggression cluster contained a significantly higher percentage of those indicating being a bully or a bully-victim compared to the other two clusters. Whereas the Low frequency cluster contained a significantly higher percentage of those indicating not being involved in bullying compared to the other two clusters. However, reporting being a victim of bullying was not associated with any one of the three clusters. Of the socio-cognitive variables, a significant incremental increase was found in the perceived acceptance of both reactive and proactive aggression as the reported frequency of the use of both types of behaviour increased across the three behavioural groups (as measured by a modified version of the RPAQ; Raine et al 2006). Conversely, an incremental decrease was observed between the frequency of the use of aggression and reported affective empathy (as measured by the Basic Empathy Scale; Jolliffe and Farrington 2006), with a significant difference being found between the Low and High frequency aggression groups. No significant differences between the groups in self-reported cognitive empathy were found. Finally, participants were asked two open-ended questions relating to their perception of why people are ‘picked on’, or ‘pick on’ others. Thematic Analysis identified a number of social representations held across the participant sample, with a further content analysis identifying that there were no significant differences in the extent to which these representations were endorsed by the three behavioural groups. The findings of the current research have important implications for our understanding of the developmental pathways for the use of reactive and proactive aggression. They identify that both types of behaviour co-occur, suggesting that the risk factors for the development of these two types of behaviour may not be so distinct and/or the risk factors associated with each are likely to co-occur. Consequently, school behaviour policies need to include strategies for addressing both forms of aggression. Interventions to reduce/prevent this behaviour need to be designed to address the risk factors which are promoting the specific motivations of both reactive and proactive behaviour.

Background. Chronic exposure to stressors in childhood has been linked with heightened risk of developing symptoms of psychosis in both clinical and non-clinical populations. The association has been explicated with reference to developmental alterations in biological and psychological systems. One such stressor, being bullied in childhood, has been the focus of recent investigations. The current study endeavoured to systematically review the available evidence from studies purporting to investigate the association between childhood bullying and psychosis symptomatology. Method. A search of PubMed, Medline, PsycInfo, Embase, Scopus and Web of Science electronic databases, alongside manual searching and cross-referencing, was carried out. The quality of available evidence for and against the association was assessed using quality assessment tools found in the literature. Results. Meeting the study’s inclusion criteria were 30 studies (eighteen cross-sectional, twelve cohort). Longitudinal studies, by design, provided higher quality evidence – particularly those which examined specifically the association between the variables of interest. However, preselected key confounding variables were not always taken into account, highlighting that the association is not unequivocal and that further research is warranted. Cross-sectional studies provide lower quality of evidence (of greater variability) where severe limitations regarding the validity and generalisability of findings must be taken into account. Conclusions. Evidence suggests that the association between experience of bullying in childhood and onset of psychotic or psychotic-like symptoms of clinical and non-clinical severity is tenable. However, future research needs to re-examine the association while minimising methodological limitations including confounding variables and definitional issues. Establishment of an association warrants investigation of the mechanisms which potentially underlie it; the pre-existing, small research base on mediators and moderators of the relationships requires further attention.

School climate is a crucial concept used to explain school differences. Nevertheless, this concept is elusive in the literature, conveying different meanings. To address the relation between school climate and school outcomes, its historical roots are reviewed and a multivariate approach to it is proposed, in contrast to a unidimensional conception. In four papers, this strategy is used to study associations among various school climate factors (SCFs) and school outcomes, including teacher turnover, teacher job satisfaction, students’ math achievement, and students’ social attitudes. In paper 1, schools serving more socioeconomically disadvantaged students are found to present higher rates of teacher turnover. A complementary study shows that SCFs (supportive school leadership, positive school relationships, and academic monitoring) present differing effects on teacher turnover. In paper 2, the relationships between SCFs (teacher student relations and school discipline) and teachers’ job satisfaction and withdrawal cognitions (intentions to quit) are estimated. These SCFs appear to play a protective role with respect to teachers’ withdrawal cognitions, and these effects are indirect via their relationship to teachers’ job satisfaction. In paper 3, the relationship between the experience of bullying and students’ achievement is addressed. The relationship is found to be indirect, with key roles played by perceptions of school belonging and students’ classroom engagement. Finally, in paper 4 the relationship between civic knowledge and the endorsement of democratic values is estimated. This link is found to be partially mediated by ideological beliefs (authoritarianism), and the role of open classroom discussion (a SCF) as a moderator of these effects is demonstrated. This work demonstrates that in order to specify theory-driven models of different school outcomes, school climate should be conceptualized as diverse social-contextual effects operating in a complex multivariate setting with mediated and moderated pathways to outcomes.

Background: It is argued that sibling relationships are often overlooked in favour of parent child relationships. Sibling interactions have the potential to be emotionally intimate and complex, and experiences can influence later psychological development. Research exploring the significance of sibling relationships is developing, with the majority of studies focussing on the protective nature of this relationship. There has been limited curiosity into the expression of adults’ stories of being bullied by a sibling in childhood. By exploring people’s stories, this study aims to consider what it means to be bullied by a sibling – that is, it will explore the broad question of “how do adults describe and make sense of their childhood sibling bullying experiences?” Method: A qualitative research paradigm was chosen for this study. The method of narrative inquiry was employed, using the Narrative Orientated Inquiry approach. Interviews were completed with seven adults who perceived themselves to have been bullied by a sibling in childhood. Results: Adults’ experiences were understood within the context of content and form. The content of people’s stories were considered alongside the way in which they told their story, facilitating an understanding of what and how they integrated their experiences into the construction of their narrative identities. Adults described their perceptions of sibling bullying and the barriers to defining experience, as well as the impact on their later, sibling relationships. The results also indicated that emotional expression associated with the event varied for every narrator, as they moved towards integration of experience. Discussion: The findings are discussed within existing theoretical models of sibling bullying and subject and identity positioning theory. The clinical implications are framed within psychoanalytic theory and in relation to the perceived acceptability of sibling bullying.
