This thesis focuses on the impact of interrogative suggestibility, compliance and negative life experiences among young people from diverse backgrounds. It comprises of three parts. The literature review in Part One presents a systematic review and narrative synthesis of studies investigating the impact of parental bereavement on adolescents. It gives thought to psychological, behavioural, social and educational outcomes for young people following parental bereavement, as well as the potential moderators and mediators of difficulties. The empirical paper in Part Two presents a cross-sectional quasi-experimental study exploring differences in interrogative suggestibility between unaccompanied asylum-seeking youth and non-asylum-seeking UK-residing youth. It explores the potential influence of compliance and negative life events on a young person's vulnerability to suggestion and interrogative pressure, while also suggesting directions for further research in this contemporary area. The critical appraisal in Part Three presents a reflection of the research process, specifically addressing some of the benefits and challenges involved in conducting research with traumatised and vulnerable young people.
