abstract="A recent suicidal drive hypothesis posits that psychotic experiences (PEs) may serve to externalize internally generated and self-directed threat (i.e.,  self-injurious/suicidal behavior [SIB]) in order to optimize survival; however, it  must first be demonstrated that such internal threat can both precede and inform  PEs. The current study conducted the first known bidirectional analysis of SIB and  PEs to test whether SIB could be considered as a plausible antecedent for PEs. Prospective data were utilized from the Environmental Risk (E-Risk) Longitudinal  Twin Study, a nationally representative birth cohort of 2232 twins, that captured  SIB (any self-harm or suicidal attempt) and PEs at ages 12 and 18 years. Cross-lagged panel models demonstrated that the association between SIB at age 12  and PEs at age 18 was as strong as the association between PEs at age 12 and SIB at  age 18. Indeed, the best representation of the data was a model where these paths  were constrained to be equal (OR = 2.48, 95% CI = 1.63-3.79). Clinical interview  case notes for those who reported both SIB and PEs at age 18, revealed that PEs were  explicitly characterized by SIB/threat/death-related content for 39% of cases. These  findings justify further investigation of the suicidal drive hypothesis.<p /> <p>Language: en</p>",
