Linking Dimensions and Dynamics in Psychopathology Research: An Example using DSM-5 Instruments

Publication date: Available online 2 August 2019Source: Journal of Research in PersonalityAuthor(s): Michael J. Roche, Aaron L. Pincus, Paige ColeAbstractThe DSM-5 includes two measures to assess dimensions of personality pathology (Personality Inventory for DSM-5; PID-5) and cross-cutting symptoms of psychopathology (DSM-5 Cross-cutting Symptom Measure; CCS). Few studies have evaluated these measures in an ecologically valid context. Participants (N=248, student sample) completed self-report versions of the DSM-5 measures, and then completed a two-week daily diary of internalizing and externalizing outcomes. The CCS scales evidenced convergent and discriminant validity with these outcomes, PID-5 Negative Affectivity and Detachment were related to internalizing outcomes, and PID-5 Antagonism was related to externalizing outcomes. We also demonstrated the benefit of linking static dimensions to temporally-dynamic processes by examining how PID-5/CCS dimensions moderated the within-person associations among daily cognitive distortions and internalizing and externalizing outcomes.
