The psychometric properties of the SDS were evaluated in primary care. The internal consistency reliability was high. The analyses also lend empirical support for the construct validity. The scale is a sensitive tool for identifying primary care patients with mental health-related functional impairment, who would warrant a diagnostically-oriented mental health assessment.

Depressed individuals contemplating suicide have cognitive rigidity, which does not appear to be a global brain dysfunction. Suicidal mental states may result from dysfunctional executive decision-making that is associated with the frontal lobe.

The DSM-III-R incorporates both distress (symptoms) and disability (impairment) in the definition of a psychiatric disorder. In psychiatric research there is a wide array of instruments used to measure symptom severity, but a limited selection for the assessment of impairment. The psychometric properties of one such instrument, The Sheehan Disability Scale (Sheehan 1983), are evaluated in this paper. The data analyzed come from two studies of patients with panic disorder, the Cross National Collaborative Panic Study--Phase I and the Panic Depression Study. In this report both the alpha coefficients and factor analyses indicate that the reliability of the scale is acceptable. The factor structure of the items and the sensitivity to change of their composite demonstrate satisfactory construct validity. The criterion-related validity is substantiated by the significant relationship between symptomatology and impairment. These analyses were limited to patients with panic disorder. Further work is needed to evaluate the instrument in assessing patients with other disorders.

Background. The social costs of anxiety disorders, which afflict a substantial proportion of the general population in the United States, are considered.Method. Data from the National Institute of Mental Health (NIMH) Epidemiological Catchment Area Program were analysed.Results. Over 6% of men and 13% of women in the sample of 18 571 had suffered from a DSM–III anxiety disorder in the past six months. Nearly 30% of those with panic disorder had used the general medical system for emotional, alcohol or drug-related problems in the six months prior to the interview. Those with anxiety disorders were also more likely to seek help from emergency rooms and from the specialised mental health system. Men with panic disorder, phobias or obsessive–compulsive disorder in the previous six months are more likely to be chronically unemployed and to receive disability or welfare.Discussion. Once correctly diagnosed there are safe and effective psychopharmacologic and behavioural treatments for the anxiety disorders. Nevertheless the burden of anxiety disorders extends beyond the direct costs of treatment to the indirect costs of impaired social functioning.

The relationship between a history of childhood abuse and subsequent sexual assault was assessed among 409 consecutive female inpatient admissions. A total of 45% of the sample reported a history of some form of childhood abuse and 22% reported at least one adulthood sexual assault. A hierarchical logistic regression indicated that, after controlling for sociodemographic and diagnostic variables, women with a history of childhood abuse were 3.1 times more likely to have experienced an adult sexual assault compared to those without abuse. There was a higher prevalence of adult sexual assault among women reporting only physical abuse or physical and sexual abuse than those reporting only sexual abuse, indicating the significance of physical abuse as a potential risk factor for adult sexual assault.
