Abstract
While previous studies have examined the relationship between psychopathic traits and alcohol use in adolescents, limited empirical investigations of the longitudinal bidirectional effects of psychopathic traits and alcohol use have been conducted for this age-group. The purpose of the present study was to examine the longitudinal associations among adolescent’s psychopathic traits and their alcohol use, in order to illustrate the directional causal relationship between the two constructs, taking into account demographic effects. Participants were 334 adolescents from Cyprus. The participants responded to self-report questionnaires in two consecutive measurements within a six-month interval. Data were analyzed with cross-lagged structural equation modelling. Results indicated that the Dependence alcohol symptoms in Time 1 were significant predictors of the Interpersonal dimension of psychopathy in T2, and the Behavioural dimension of psychopathy in T1 was a significant predictor of Dependence alcohol symptoms in T2, regardless of previous levels of psychopathy and alcohol use, gender and age effects. Implications for research are discussed.
