Extending the nomological network of sexual objectification to psychopathic and allied personality traits.

Although the causes and correlates of sexual objectification almost certainly comprise a heterogeneous array of individual difference variables, little is known about sexual objectification perpetration's nomological network. We hypothesized that the broad personality construct of psychopathy would afford a fruitful framework for understanding and statistically predicting sexual objectification and investigated the implications of a host of psychopathic and psychopathy-related traits, including empathy, narcissism, impulsivity, and sadism, for interpersonal sexual objectification perpetration (ISOP). We augmented an extant self-report instrument of behavioral sexual objectification, the Interpersonal Sexual Objectification Scale-Perpetrator Version (Gervais, DiLillo, & McChargue, 2014), with attitudinal items. Two Mechanical Turk samples (Study 1: N = 401, 53% female, M age = 36; Study 2: N = 419, 48% female, M age = 37) were administered the augmented Interpersonal Sexual Objectification Scale-Perpetrator Version and a battery of well validated self-report instruments describing psychopathic and psychopathy-related traits. Dark personality traits were strongly associated with sexual objectification; sadism, low affective empathy, narcissism, disinhibition, and meanness emerged as the largest correlates. Further, our hypothesis that psychopathic traits would moderate (potentiate) the relation between ISOP attitudes and ISOP behaviors found support in both samples.
