The psychopathy checklist--screening version: an examination of criteria and subcriteria in three forensic samples.

The development and refinement of psychopathy represent a critical issue in clinical and forensic practice. During the last decade, important advances in the operationalization of psychopathy were achieved, primarily through the development of the Psychopathy Checklist (PCL) and its subsequent versions (PCL-R and PCL:SV). PCL ratings are based primarily on item descriptions or subcriteria. The current study serves to break new ground as the first systematic investigation of PCL:SV subcriteria by addressing their psychometric properties and exploring their construct and criterion-related validation. Previously unanalyzed data from three samples were integrated: female offenders, male forensic patients, and male adolescent offenders. Results largely support the use of subcriteria as homogeneous components of criteria and provide strong initial evidence of their construct validity. Results are less conclusive regarding criterion-related validity. For female offenders, they suggested the potential value of specific PCL:SV subcriteria for predicting verbal aggression. Confirmatory factor analysis provided encouraging results on the applicability of the standard two-factor model of psychopathy. However, a first-order principal axis factoring suggested further refinements in our understanding of psychopathy.

The contribution of small life events to the psychological distress of married and widowed older women.

The contribution of small life events to the prediction of general psychological distress was examined for 50 married and 21 recently widowed older women. These two groups were contrasted as having or not having experienced an uncontrollable major life stressor (i.e., the recent death of a spouse). Negative small life events (i.e., daily hassles) contributed above and beyond general demographic factors; conjugal bereavement status; social support; other, non-conjugal bereavement, major life events; and the interaction of these life events and social support in the prediction of general psychological distress. Results support assessing negative small life events as well as major life events for both married and recently widowed older women.

Locus of control perceptions among conjugally bereaved older adults: a pilot study.

While Locus of Control is typically operationalized as a single dispositional trait that generalizes across settings, it has also been conceptualized as two weakly related factors; Domain-Specific State Locus of Control and a generalized Trait Locus of Control. Malleability of these two factors was tested for recently widowed older adults in self-help support groups (n = 17) and a waiting-list control condition (n = 6). Domain-Specific State Locus of Control-Desire for Control subscale increased over the course of the three-week six-session intervention for support group participants. These group participants also showed decreased psychological distress from pre to post intervention. The change in Domain-Specific State Locus of Control-Desire for Control did not relate to this reduction in distress. As expected, Trait Locus of Control remained stable with greater Trait Internality related to less psychological symptomatology.
