Proposed Specifiers for Conduct Disorder (PSCD) self‐report: Factor structure and validation in a community sample of Belgian youth

Abstract

AbstractThe current study examined the psychometric properties of the Proposed Specifiers for Conduct Disorder (PSCD) in a sample of school‐attending adolescent Belgian youth (N = 599; M age = 16.51 years, SD = 1.27). Given the recent interest in the PSCD‐Short Version (PSCD‐SV), this study focused on the 13‐item variant of the PSCD. Study findings showed that the PSCD‐SV had a hierarchical four‐factor structure including the components of grandiose‐manipulative (GM), callous‐unemotional (CU), daring‐impulsive (DI), and conduct disorder (CD). These interrelated factors were found to be internally consistent. The study also showed that the PSCD‐SV total score was positively and significantly related to an alternate measure of psychopathy. Further, the study revealed the PSCD‐SV was meaningfully related to the five‐factor personality domains (i.e., extraversion, conscientiousness, agreeableness) as well as peer functioning and prosocial behavior. Bivariate correlations demonstrated that the dimensions differed in their associations with external correlates (e.g., peer functioning). Regression analyses showed that the GM, CU, and CD components of the PSCD‐SV were uniquely associated to externalizing difficulties, whereas only the GM and CU components of the PSCD‐SV were associated with low prosocial behaviors. These findings shed light on the conceptual and developmental models for the consideration of psychopathy and conduct problems. The use of the broader psychopathy condition as well as its underpinning dimensions may have important implications for assessment, treatment, and diagnostic manuals. The implications of the current study are further discussed.
