Abstract The current study investigated Lilienfeld’s (1992) sex differentiation hypothesis. Modifications were made to highlight the importance of examining social expectations of acceptable behavior for women and men. Modifications were also made to move away from broad constructs (i.e. negative emotionality and behavioral disinhibition) and instead examine narrower constructs (i.e., anxiety and impulsivity) with more explanatory utility. Results support the utility gender role in predicting antisocial symptoms, but not somatic symptoms. Some support for a relationship between somatization and impulsivity as predicted by the behavioral disinhibition hypothesis was found, but results indicate that the relationship between somatization and antisociality is better accounted for by anxiety, and this is consistent with the negative emotionality model. The sex-differentiation aspect of Lilienfeld’s hypotheses was largely unsupported. Future research in the area can benefit from attending to the cautions presented in this paper, as well as the limitations noted.
