Psychological implications of the Psychopathy Q-sort.
The construct validity of the Psychopathy Q-sort (PQS; Reise & Oliver, 1994) was investigated by correlating it with an array of observer-based and self-report personality measures in a sample of 350 men and women assessed at the Institute of Personality Assessment and Research (IPAR). High discriminant validity of the PQS was indicated by a pattern of significant correlations with self-report measures of the Cluster B personality disorder scales of the Diagnostic and Statistical Manual of Mental Disorders (3rd ed., rev.; American Psychiatric Association, 1980) and the absence of correlations with scales belonging to Clusters A and C of the manual. The PQS also correlated positively with the California Psychological Inventory measures of social poise and assurance and correlated negatively with measures of normative control of impulse. Gender differences in psychopathy were explored using Adjective Check List (Gough & Heilbrun, 1983) ratings provided by IPAR staff observers and by 76 pairs of spouses.
