Abstract

Aims: This portfolio aims to understand the impact of mental health diagnosis in youth with a history of offending and its impact on factors that affect juror decision making in legal settings. This portfolio also investigates the prevalence of Post-Traumatic Stress Disorder (PTSD) in in youth with a history of offending.

Design: The portfolio outlines a general introduction, a systematic review and meta-analysis of the prevalence of PTSD, and an empirical paper exploring the impact of the diagnosis ‘Severe Personality Disorder, Borderline Pattern’ ICD-11 classification on mock juror decision making in a homicide trial. An overall discussion and critical evaluation chapter is also outlined. This study is a replication of Baker et al., (2022) in terms of its design, but it investigates the impact of mental health diagnosis for an adolescent on trial specifically.

Findings: The systematic review and meta-analysis findings are consistent with the existing literature; such that youth with a history of offending exhibit elevated levels of PTSD when compared with the general population, especially in female youth. The findings from the empirical paper suggest that the presence of mental health diagnosis does not impact mock juror decision making, stigmatising attitudes or causal attributions made for an adolescent on trial for homicide. Instead, the perception of the adolescent’s personal control over their behaviour, significantly predicted mock jurors’ decision regarding the legal defence of Diminished Responsibility.

Significance of the portfolio: This portfolio makes an important contribution to understanding factors that may influence juror decision making for an adolescent on trial. This has significant implications for the way clinical information about youth is presented in legal settings. The work in this portfolio also sheds light on the importance of timely and standardised assessments of PTSD for youth with a history of offending.
