The goal of the current investigation was to evaluate the Lithuanian translation of the Triarchic Psychopathy Measure (TriPM; Patrick, 2010) as well as more broadly extend the construct validity of this psychopathy measurement model to forensic and correctional criteria. Two samples derived from male Lithuanian correctional facilities were merged for this study. The TriPM Meanness and Disinhibition scales evinced acceptable internal reliability coefficients, whereas that for the TriPM Boldness scale was in the questionable range. All three TriPM scales were generally associated with external criteria reflecting psychopathy, aggression, and transdiagnostic clinical and personality constructs in ways consistent with the extant literature, though TriPM Boldness evinced surprisingly small negative correlations with measures of negative emotionality and fear. Furthermore, TriPM Disinhibition was associated with the largest correlations with two risk assessment measures. Implications of these findings in the context of the broader literature are discussed.
