The concurrent and progressive validity analysis of triarchic psychopathy measure in adolescents sample

The Triarchic psychopathy model was proposed by Patrick, Fowles, and Krueger (2009). The model was operationalized with Triarchic Psychopathy Measure (TriPM) (Patrick, 2010). To assess the convergent and predictive validity of the TriPM in a sample of 159 Lithuanian juvenile offenders number of measures was used: Short-Term Assessment of Risk and Treatability: Adolescent Version (START:AV) (Viljoen, Nicholls, Cruise, Desmarais, & Webster, 2014), Subtypes of Antisocial Behaviour Questionnaire (STAB) (Burt & Donnellan, 2009), Criminal Sentiments Scale – Modified (CSS-M) (Shields & Simourd, 1991), Sense of Coherence Scale (SOC) (Antonovsky, 1987). Subsequently, in the three-month follow-up period information related to juveniles’ misbehaviours was collected. The results of the research showed significant corellations with TriPM scales scores, and these relationships were consistent with results reported for Lithuanian adults offenders (Selbom, Laurinavičius, Ustinavičiūtė, Laurinaitytė, 2018). The TriPM scales were associated with concurrent measures in an expected direction, the effect sizes varied from small to large. The results of AUC for several forms of misconduct in a three-month period confirmed predictive validity of the TriPM scales: Meanness scores were associated with an occurrence of aggressive behavior, Disinhibition with unauthorized absence, Boldness – with alcohol use. The results of our research findings provide support for the validity of the TriPM in juveniles.
