85. The relation between positive symptoms and suicidal ideation and behaviors in adolescents at clinical high risk for psychosis.
Suicide is the second leading cause of death in adolescents in the United States (CDC, 2016). Individuals with schizophrenia and other psychotic disorders are at a greater lifetime risk of suicide than the general population, with the highest risk occurring at the beginning stages of diagnosis (Cassidy et al., 2018; Ventriglio et al., 2016). Moreover, a recent meta-analysis reported that the prevalence of suicidal ideation and suicide attempts in individuals at clinical high-risk for psychosis was 66% and 18%, respectively (Taylor, Hutton, & Wood, 2015). Despite this elevated risk, research on the attenuated positive symptoms associated with suicidality are less clear. This study seeks to determine the relation between positive attenuated symptoms and suicidal ideation and behaviors, and is part of an ongoing, longitudinal study conducted at the SFW Clinic at the UMBC’s YouthFIRST lab and the UMMC. The Kiddie Schedule for Affective Disorders and Schizophrenia, Present and Lifetime Version (K-SADS; Kaufman et al., 2013) will be used to determine highest lifetime suicidal ideation and behaviors. The Structured Interview for Psychosis Risk Syndromes (SIPS; Miller et al., 2003) will be used to assess CHR status and presence and severity of positive symptoms. Although data collection is ongoing, preliminary results suggest that suicidal ideation and attempts are associated with unusual thought content and suspiciousness. Findings may provide insight into the nature of specific positive symptoms related to suicidality for those at CHR, and could provide clues towards effective clinical intervention targets.
