Oppositional Defiant Disorder Dimensions: Associations with Traits of the Multidimensional Personality Model among Adults.

The occurrence of Oppositional Defiant Disorder (ODD) behaviours among adults has been supported by a proportion of scholars. The current work examines potential ODD dimensions and their associations with the primary personality traits of Tellegen's [57] multi-dimensional conceptualization during adulthood. Two independent, general community, adult groups [Group 1: N = 214; mean age (SD) = 35.74 (16.60); Group 2: N = 205; mean age (SD) = 29.00 (12.42)] completed the Current Symptom Scale involving the eight ODD criteria. Group 2 additionally addressed the Multidimensional Personality Questionnaire -Brief Form (MPQ-BF). A series of Confirmatory Factor Analyses (CFA) were implemented. The three-dimensional ODD conceptualization of Burke and colleagues [14] referring to "Negative Affect", "Oppositional Behavior", and "Antagonistic Behavior" was confirmed. Considering personality traits, valuable associations were revealed between Oppositional Behavior and Aggression, Antagonistic Behavior and Social Potency as well as Harm Avoidance, and finally, Negative Affect and Stress Reaction, as well as Aggression. The dimensionality of ODD behaviours in adulthood and its correspondence with particular personality traits is approached in the context of psychological practice.
