Wang, Wenzheng Bian, Qian Zhao, Yan Li, Xu Wang, Wenwen Du, Jiang Zhang, Guofang Zhou, Qing Zhao, MinДepression is one of the most common mental illnesses. Reliability and validity of the Chinese version of the Patient Health Questionnaire ( PHQ- 9) in the general population. Significance The PHQ- 9 is an efficient & non-proprietary depression screening instrument with excellent accuracy validated for use in adult epilepsy patients as well as multiple other medical populations. The areas under the ROC curves of the PHQ- 9 and the NDDI-E showed similar accuracy (n=127 0.930 vs 0.934 p=0.864). At cut-points of 10 and 15, respectively, the PHQ- 9 had higher sensitivity (0.92 vs 0.87), but lower specificity (0.74 vs 0.89) than the NDDI-E. Results The calculated areas under the ROC curves for the PHQ- 9 (n=172) and the PHQ- 9/CA and PHQ- 9/S sub-scales were 0.914, 0.924, and 0.846, respectively, with the PHQ- 9 more accurate than the PHQ- 9/S (p=0.002) but no different than the PHQ- 9/CA (p=0.378). The PHQ- 9 was divided into cognitive/affective ( PHQ- 9/CA) and somatic ( PHQ- 9/S) subscales to determine comparative depression-screening accuracy. Cut-points of 10 for the PHQ- 9 and 15 for the NDDI-E were used and ratings at or above the cut-points were considered screen-positive. Sensitivity, specificity, positive & negative predictive values & areas under the ROC curves for each instrument were determined. Methods Tertiary epilepsy center patients served as the study population with 237 agreeing to structured interview using the Mini-International Neuropsychiatric Interview (MINI), a Гўв‚¬Е“gold standardГўв‚¬Вќ instrument developed for rapid diagnosis of neuropsychiatric disorders, including major depressive disorder (MDD) 172 also completed the PHQ- 9, and 127 completed both the PHQ- 9 and the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E) within two days of the MINI.

Objective Assess accuracy and operating characteristics of the Patient Health Questionnaire- 9 ( PHQ- 9) for depression-screening in adults with epilepsy. Foldvary-Schaefer, Nancy Ramirez, Maya J. Validation of the Patient Health Questionnaire- 9 ( PHQ- 9) For Depression Screening in Adults with Epilepsy This underscores the need to provide effective mental health outreach and treatment, including lifestyle modification, at an early stage in college life. The results suggest that there is a strong relationship between the severity of depressive symptoms and the lifestyles of college students. Moreover, the students who never ate 3 meals daily had higher PHQ- 9 scores than those who did.

PHQ- 9 scores in the students who never ate breakfast were higher than those who ate breakfast everyday. The students who slept less than 5 hours and more than 8 hours had significantly higher PHQ- 9 scores than those who slept 6-7 hours. PHQ- 9 scores in the students who had unsatisfactory sleeping habits were significantly higher than those in the students who felt they had satisfactory sleep. The students feeling stressed had significantly higher PHQ- 9 scores than those that felt no stress. The average PHQ- 9 scores in the 1st school year were significantly higher than those of the 4th school year. The students with PHQ- 9 scores of 15 or higher were 9.2%. Overall, the average PHQ- 9 score was 7.7 +/- 5.1 (SD). One hundred and fifty-two college students finally participated. Additional questions were focused on current stress levels and sleeping, eating, and exercising habits. The principal measure of depressive symptoms was the 9-item depression module from the Patient Health Questionnaire ( PHQ- 9). The objective of this investigation was to examine depression in, and the lifestyles of, 260 college students of a nursing school in nonclinical settings. Urasaki, Midori Oshima, Nozomi Okabayashi, Ayako Sadatsune, Mai Shibuya, Aki Nishiura, Akina Takao, Toshihiro The Patient Health Questionnaire ( PHQ- 9) scores and the lifestyles of nursing students.
