Study to Examine Psychological Processes in Suicidal Ideation and Behavior (STEPPS).

摘要

This study aims to address the dearth in basic science in suicidology by looking at components of two new psychological models that endeavor to identify suicide-specific individual differences factors and patterns of thinking; the Integrated Motivational Volitional Model (IMV; O'Connor 2011) and the Interpersonal Psychological Theory of Suicide (IPT; Joiner, 2005). The project is divided into 6 separate studies (experimental, prospective, clinical) that aim to advance our understanding of the basic psychological processes associated with suicidal ideation and behavior. Study 1; the Scottish Wellbeing Study is a large scale general population based prospective study of young people across Scotland. Study 2 uses a clinical population of patients recently admitted to hospital for self-harm with follow-up. Studies 3 and 4 are longitudinal studies that incorporate an experimental component designed to compare changes in pain sensitivity before and after a social stress or defeat manipulation. Studies 5 and 6 investigate the relationship between heightened stress reactivity and suicidality in both a laboratory and real-life setting. Baseline recruitment is complete for studies 1, 2 and 5 and is ongoing for studies 3, 4,and 6.
