Abstract

Objective: To examine the utility of the Self-Report Psychopathy-Short Form (SRP-SF) to assess psychopathic traits in female offenders and to test gender-based item modifications.

Method: A South American sample of female offenders (n=210) was assessed with the Psychopathy Checklist-Revised (PCL-R); 110 subjects also completed the standard SRP-SF, while 109 completed a version with items rewritten to be more relevant for females. The underlying latent structure of the PCL-R and both versions of the SRP-SF were examined.

Results: Most of the modified items showed higher average item responses. The PCL-R showed a stronger association with the modified SRP-SF than with the standard SRP-SF. The four-factor model showed very good fit in accounting for the PCL-R data, consistent with previous research. For both SRP-SF versions, the results indicated good model fit. Structural equation models were tested separately, in which a superordinate SRP-SF factor was set to predict a broad factor reflecting chronic misconduct. Both versions showed good model fit, and the SRP-SF superordinate factor significantly predicted a chronic misconduct factor.

Conclusions: Both versions of the SRP-SF adequately reflected psychopathic features in this female sample; the modified items added robustness to representation of these features.
