Psychopathy has rarely been studied in the wife rapist population. The hypothesis of our study was that the characteristics of the spouse sexual offenders refer more to a psychopatic functioning than the non-spouse sexual offenders. A sample of 27 spouse sexual offenders and 70 non-spouse sexual offenders was selected. The «Psychopathy Checklist Revised» (PCL-R) was used to evaluate psychopathy. The results were that only five subjects meet the criterion of psychopathy in the whole sample. On a categorial basis, difference appeared in the distribution of the different samples among the cases categorised as ‘’mixed’’ and the ‘’non-psychopaths’’, the spouse sexual offenders being more often diagnosed as ‘’mixed’’ and the non-spouse sexual offenders being more often diagnosed as ‘’non-psychopaths’’. On a dimensional basis, the mean score at the PCL-R of the spouse sexual offenders was significantly higher than the non-spouse sexual offenders.
