Response perseveration in psychopathic women

Area of Science:

• Forensic Psychology
• Clinical Psychology
• Neuropsychology

Background:

• Validating the Psychopathy Checklist-Revised (PCL-R) in female offenders is crucial for accurate assessment.
• Previous research has not adequately explored laboratory correlates of psychopathy in women.
• Understanding psychopathy in female offenders requires examining behavioral and cognitive markers.

Purpose of the Study:

• To validate the PCL-R as a measure of psychopathy in a sample of incarcerated women.
• To investigate laboratory correlates, specifically response perseveration, in psychopathic female offenders.
• To determine if findings from male psychopathy research generalize to female offenders.

Main Methods:

• 112 incarcerated women were assessed using the PCL-R.
• Participants completed a card perseveration task, a measure sensitive to response perseveration.
• Performance on the task was analyzed dimensionally and categorically based on PCL-R scores.

Main Results:

• Contrary to predictions, women identified as psychopathic did not exhibit increased response perseveration.
• No significant perseveration was observed regardless of whether the PCL-R was treated as a dimensional or categorical measure.
• These results suggest a potential difference in the expression of psychopathy between genders.

Conclusions:

• The PCL-R's utility and interpretation in female offenders may require re-evaluation.
• Response perseveration may not be a reliable laboratory correlate of psychopathy in women.
• Further research is needed to understand the nuances of female psychopathy and its assessment.
