A new proposed factor structure: reliability and validity of the diagnostic and statistical manual formental disorders scale for depression.  Toru Uehara, Kazuo Takeuchi, Robert E Roberts


Depression on college campuses is recognized as an important issue for mental health maintenance. Valid and user-friendly measurement methods are necessary to implement campus screening programs. This study investigated psychometric properties of the Diagnostic and Statistical Manual for the Mental Disorders Scale for Depression (DSD). The authors describe the reliability and validity of the Japanese version of the DSD toexamine the utility of this algorithm-based self-rating questionnaire. A new algorithm was proposed to improve diagnostic performance. To confirm classical reliability tests and to do factor analyses, 6592 university students were examined. Diagnostic performance was analyzed for 84 students using interviews conducted by a psychiatrist.  Internal consistency coefficients were excellent. Five factor solutions were indicated as follows: psychomotor inhibition, depressive mood, suicidal thoughts, atypical features, and weight gain. The original algorithm provided high specificity and low sensitivity. The new five-factor algorithm improved sensitivity and decreased false positives. The DSD is useful to diagnose major depressive episodes conveniently and reliably. Its subscales can evaluate those symptoms which suggest a depression profile. Future studies should examine clinical applications and their concurrent and discriminant validity.    Full Article


Effects of Social Support on Cardiovascular and Cortisol Reactivity during Passive and Active Behavioral Challenge.   Einar B. Thorsteinsson, Jack E. James, M. Elizabeth Douglas, Mary M. Omodei


The effects of social support on cardiovascular and cortisol reactivity during stressful situations were examined. Sixty healthy male and female participants were randomly allocated to support, no-support, or alone conditions. In the active challenge, participants had higher diastolic blood pressure in the support than the alone condition. In the passive challenge, the support condition reduced systolic and diastolic blood pressure reactivity compared with nosupport, and heart rate compared with the alone condition. The active and passive challenges elicited “mixed” and vascular hemodynamic profile, respectively. The results partly support the health benefits of support through reduced reactivity in stressful situations.  Full Article
