CHILDHOOD ABUSE AND ADVERSE EXPERIENCE IN ADOLESCENTS WHO HARM OTHERS (Rebecca Louise Doyle, BA PGDip MSc) Thesis submitted to the University of Nottingham for the degree of Doctor in Forensic Psychology (D.Foren.Psy) (July 2014) Abstract This thesis explores the effects of adverse childhood experience, including childhood abuse and neglect, on adolescents. More specifically, it explores these effects in relation to offending behaviour. A literature review considered research investigating differences between sexual and non- sexual offenders. More consistent differences were identified for adolescents who sexually offend against children, as opposed to those who offend against peers / adults, when compared to other groups of offenders. Studies in this area are, however, subject to methodological limitations. Following this, an empirical research project investigates the prevalence and characteristics of adverse childhood experience in a sample of mixed sex adolescents detained in a medium secure specialist psychiatric hospital, alongside psychopathological traits. Male sexual offenders differed from violent offenders on a number of variables, including experiences of sexual abuse and a diagnosis of a Learning Disability (LD). Then, a single case study is highlighted which investigates and demonstrates the influence of adverse childhood experience and cognitive impairment on vulnerabilities and offending behaviour in an adolescent male detained in the aforementioned secure psychiatric hospital. The effectiveness of the intervention, designed to address this individual’s difficulties with emotional recognition and regulation, is demonstrated by changes in psychometric assessments scores and via clinical observation of behaviour. Finally, a critique is presented of the Coping Responses Inventory – Youth Form (CRI-Y) (Moos, 1993). This is a psychometric measure designed to measure styles of coping in adolescents. It is critically evaluated to demonstrate its psychometric properties, and its validity for clinical settings. This thesis emphasises the importance of considering developmental experience in the onset of offending behaviour, and the importance of engineering more comprehensive, systemic, and targeted early intervention programmes for individuals deemed at risk of committing particular offences or becoming delinquent in adolescence. II Preface / Overview This thesis aims to explore the effects of childhood abuse and adverse childhood experience in terms of their application to offending behaviour in adolescence. Sexually offensive behaviours, violence, and general delinquency are considered. A developmental approach is used to consider the effects of such experiences on the onset of offending behaviour, such as by disrupting childhood attachments and causing vulnerabilities, including poor coping styles and poor interpersonal skills. Chapter One explores and critically examines empirical studies that have investigated childhood abuse and adverse childhood experience in adolescents who have sexually offended against others whilst comparing them to adolescents who have either not done so, but have offended in another way, or who have not offended. This review used comprehensive search strategies and stringent inclusion criteria for studies conducted between 1975 and 2012. Methodological limitations of these studies are considered. This review informed Chapter Two’s empirical research project’s selection of variables pertaining to adverse childhood experience, and its classification of sexual offenders according to victim (i.e. offences against children or offences against peers / adults). Chapter Two is an empirical research project that explores adverse childhood experience in a sample of inpatient adolescents who are detained in a specialist medium secure psychiatric hospital. A retrospective systematic file review of patient records was conducted to establish the presence of variables of interest. 45 adolescents (32 male and 13 female) consented to take part. Data were used to establish whether a relationship existed between adverse childhood experience and type of offences committed. Psychopathological traits upon detention in hospital were also observed amongst groups of offenders. A number of differences are identified between groups. Methodological limitations and III avenues for future research are discussed. Furthermore, clinical implications are also highlighted. Chapter Three explores, in a single case study format, the assessment, formulation, and intervention for an adolescent male characterised by adverse childhood experience and cognitive impairment. This individual is detained in the same specialist secure hospital described above. A psychological formulation and discussion clearly highlights the influence of these factors on the onset and continuation of offending behaviour, as theorised in Chapter Two. The intervention used cognitive-behavioural affective education, simplified and collaborative functional analyses, self- monitoring of emotions, and the encouragement of adaptive coping skills to address risk-related difficulties. Chapter Four provides a critique of the Coping Responses Inventory – Youth Form (CRI-Y) (Moos, 1993). This measure is critically evaluated in terms of its development, its psychometric properties, and normative data. Further application and research with adolescents who have offended against others is also considered, in light of theoretical literature pertaining to the influence of poor coping on vulnerabilities theorised to be present in some adolescent offenders, such as social isolation and sexual offending, as highlighted in previous Chapters. Finally, Chapter Five concludes this thesis. It provides an overview and discussion of the work and findings presented in previous chapters, as well as considering how they influence each other. Limitations are noted, as well as considerations for further research and implications for practice.
