A study of the diagnostic accuracy of the PHQ-9 in primary care elderly

<p>Abstract</p> <p>Background</p> <p>The diagnostic accuracy of the Patient Health Questionnaire-9 (PHQ-9) for assessment of depression in elderly persons in primary care settings in the United States has not been previously addressed. Thus, the purpose of this study was to evaluate the test performance of the PHQ-9 for detecting major and minor depression in elderly patients in primary care.</p> <p>Methods</p> <p>A prospective study of diagnostic accuracy was conducted in two primary care, university-based clinics in the Pacific Northwest of the United States. Seventy-one patients aged 65 years or older participated; all completed the PHQ-9 and the 15-item Geriatric Depression Scale (GDS) and underwent the Structured Clinical Interview for Depression (SCID). Sensitivity, specificity, area under the receiver operating characteristic (ROC) curve, and likelihood ratios (LRs) were calculated for the PHQ-9, the PHQ-2, and the 15-item GDS for major depression alone and the combination of major plus minor depression.</p> <p>Results</p> <p>Two thirds of participants were female, with a mean age of 78 and two chronic health conditions. Twelve percent met SCID criteria for major depression and 13% minor depression. The PHQ-9 had an area under the curve (AUC) of 0.87 (95% confidence interval [CI], 0.74-1.00) for major depression, while the PHQ-2 and the 15-item GDS each had an AUC of 0.81 (95% CI for PHQ-2, 0.64-0.98, and for 15-item GDS, 0.70-0.91; <it>P </it>= 0.551). For major and minor depression combined, the AUC for the PHQ-9 was 0.85 (95% CI, 0.73-0.96), for the PHQ-2, 0.80 (95% CI, 0.68-0.93), and for the 15-item GDS, 0.71 (95% CI, 0.55-0.87; <it>P </it>= 0.187).</p> <p>Conclusions</p> <p>Based on AUC values, the PHQ-9 performs comparably to the PHQ-2 and the 15-item GDS in identifying depression among primary care elderly.</p

Enabling the nation's schools to help prevent heart disease, stroke, cancer, COPD, diabetes, and other serious health problems.

In the United States, more than 53 million young people attend nearly 120,000 schools, usually for 13 of their most formative years. Modern school health programs--if appropriately designed and implemented--could become one of the most efficient means the nation might employ to reduce the establishment of four main chronic disease risks: tobacco use, unhealthy eating patterns, inadequate physical activity, and obesity. The U.S. Centers for Disease Control and Prevention and its partners have developed four integrated strategies to help the nation's schools reduce these risks. Participating national, state, and local agencies (1) monitor critical health risks among students, and monitor school policies and programs to reduce those risks; (2) synthesize and apply research to identify, and to provide information about, effective school policies and programs; (3) enable state, large city, and national education and health agencies to jointly help local schools implement effective policies and programs; and (4) evaluate implemented policies and programs to iteratively assess and improve their effectiveness

Using Theory to Support Classroom Teachers as Physical Activity Promoters

Recently, there has been growing attention on the importance of the staff involvement component of a comprehensive school physical activity program (CSPAP). In particular, classroom teachers (CTs) are increasingly being called upon to promote physical activity (PA) in their classrooms as part of the PA during school component of a CSPAP. Consistent with this view, a burgeoning research base highlights several theoretical perspectives that provide insight into key factors associated with CTs' classroom-based PA promotion. The purpose of this article is to provide an up-to-date, comprehensive review of the theoretically framed research on CTs' classroom-based PA promotion and consider the implications of this research for the design of in-service professional development trainings that can be used to maximize staff involvement in CSPAPs.</p
