Development and initial validation of a brief mental health outcome measure.

Using a combination of classical test theory and Rasch item analysis, we developed a short scale designed to measure the effectiveness of mental health treatment across a wide range of mental health services and populations. Item development for the scale was guided by literature review and interviews with senior clinicians and with patients. Using 3 different samples consisting of inpatients, outpatients, and nonpatients, we reduced our initial item pool from 81 to 10 items. The 10-item scale had an alpha of .96 and showed strong correlations with commonly used measures of psychological well-being and distress. Our results suggest that the scale appears to measure a broad domain of psychological health. The scale appeared to lack ceiling and floor effects, and it discriminated between inpatients, outpatients, and nonpatients, suggesting the scale has excellent potential to be broadly responsive to a variety of treatment effects. In addition, the new scale proved to be sensitive to treatment changes in a sample of 20 psychiatric inpatients. Overall, the initial data suggest that we have developed a brief, sensitive outcome measure designed to have wide application across psychiatric and psychological treatments and populations.

The relationship of menstrual cycle and pregnancy to compulsive hairpulling.

BACKGROUND: Trichotillomania (TTM) or compulsive hairpulling is a cyclical disorder that presents predominantly in females. Anecdotal reports of symptom worsening in the premenstruum and during pregnancy led us to retrospectively study the role of these events in hairpulling behavior. METHODS: Questionnaires assessing demographics, current hairpulling behavior, and the reported effects of menstruation and pregnancy on urges, actual hairpulling and behavioral control were administered to clinic patients and volunteers at a hairpulling conference. The MGH Hairpulling Scale, Beck Depression Inventory and Beck Anxiety Inventory were also completed. Data from 59 hairpullers were analyzed. RESULTS: Premenstrual symptom exacerbation was reported for actual hairpulling urge intensity and frequency, and ability to control pulling and was alleviated during menstruation and shortly thereafter. The impact of pregnancy was less unidirectional, with both symptom exacerbation and lessening reported. CONCLUSIONS: The menstrual cycle appears to affect compulsive hairpulling and deserves recognition in both the assessment and treatment of this disorder. The impact of pregnancy on TTM is less clear.
