Josh Weller - An examination of triarchic psychopathy scales
Because the construct of psychopathy is of chief interest across different disciplines, spanning developmental, clinical, and forensic psychology, its assessment bears far-reaching implications. One prominent contemporary conceptualization of psychopathy, the Triarchic Model, posits that a psychopathic personality encompasses three phenotypic constructs: boldness, meanness, and disinhibition. The present study examined the longitudinal measurement invariance and the construct validity of triarchic psychopathy scales (MPQ-Tri) in a large and diverse high-risk sample (N = 716) across four time points from age 16 to age 25. On balance, the present findings suggest that the MPQ-Tri scales fulfill their intended purpose, with some noted limitations,and provide grounds for the use of the MPQ-Tri scales in developmentally-informed studies on the etiology and consequences of psychopathy.
