Abstract

Two samples with heterogeneous prevalence of externalizing psychopathology were used to investigate the structure of self‐regulatory models of behavioral disinhibition and cognitive capacity. Consistent with expectations, structural equation modeling in the first sample (N=541) showed a hierarchical model with 3 lower order factors of impulsive sensation seeking, antisociality/unconventionality, and lifetime externalizing problem counts, with a behavioral disinhibition superfactor best accounted for the pattern of covariation among 6 disinhibited personality trait indicators and 4 externalizing problem indicators. The structure was replicated in a second sample (N=463) and showed that the behavioral disinhibition superfactor, and not the lower order impulsive sensation seeking, antisociality/unconventionality, and externalizing problem factors, was associated with lower IQ, reduced short‐term memory capacity, and reduced working memory capacity. The results provide a systemic and meaningful integration of major self‐regulatory influences during a developmentally important stage of life.
