The inventory contains 21 self-report items which individuals complete using multiple choice response formats. The unaided clinical diagnoses yielded a sensitivity of 12.5% and a specificity of 96.0%.The Beck Depression Inventory (BDI) is widely used to screen for depression and to measure behavioral manifestations and severity of depression. Although the categorical algorithm of the PHQ-9 was most specific (94.7%), sensitivity was just above chance (52.5%). At optimal cutoffs, there was no significant difference in sensitivity ( PHQ-9: 90.0%, PHQ-2: 85.0%), but in specificity (PHQ-9: 86.5%, PHQ-2: 79.4%). Results indicate the AUC of the PHQ-9 (93.2%) was significantly higher than that of the PHQ-2 (87.2%). In addition, unaided clinical depression diagnoses by the attending pediatricians were evaluated. Validity measures of both scoring procedures of the PHQ-9 as well as PHQ-2 were compared statistically. Besides the dimensional algorithm, a categorical algorithm was applied for the PHQ-9. Areas under the receiver operating characteristics curve (AUCs) and sensitivities and specificities at optimal cutoff points were computed for both versions of the PHQ. Criterion validity of the PHQ-9 and PHQ-2 was assessed against diagnoses of any depressive disorder provided by a structured diagnostic interview. Adolescents were recruited from pediatric hospitals. This study examines the criterion validity of the Patient Health Questionnaire 9-item ( PHQ-9) and 2-item (PHQ-2) version as a depression screening instrument for adolescents. Participants - 322 youth aged 13 to16 years Screening for depression in adolescents: validity of the patient health questionnaire in pediatric care. K., Pietsch, K., Frühe, B., Sigl‐Glöckner, J., & Schulte‐Körne, G. Increasing PHQ-9 scores were significantly correlated with increasing levels of functional impairment, as well as parental report of internalizing symptoms and psychosocial problems.Īllgaier, A. Receiver-operator-curve analysis revealedthat the PHQ-9 had an area under the curve of 0.88 (95% confidence interval: 0.82– 0.94), and the cut point of 11 was optimal for maximizing sensitivity without loss of specificity.
#Phq 9 adolescent validity and reliability manual
Results indicate A PHQ-9 score of 11 or more had a sensitivity of 89.5% and a specificity of 77.5% for detecting youth who met the Diagnostic andStatistical Manual of Mental Disorders, Fourth Edition criteria for major depression on the DISC-IV. Construct validity was tested by examining associations between the PHQ-9 and a self-report measure of functional impairment, as well as parental reports of child psychosocial impairment and internalizing symptoms. Criterion validity and performance characteristics were assessed against an independent structured mental health interview (the Child Diagnostic Interview Schedule ). The PHQ-9 was completed by youth who were enrolled in a large health care– delivery system and participated in a study on depression outcomes. The purpose of this study was to examine the performance characteristics and validity of the Patient Health Questionnaire-9 Item ( PHQ-9) as a screening tool for depression among adolescents. Participants - 442 youth aged 13 to17 years Evaluation of the Patient Health Questionnaire-9 Item for detecting major depression among adolescents. The area under the receiver operating characteristic curve for PHQ-9 was. The concordance rate between the PHQ-9 threshold score of 10 and the International Classification of Diseases, 10th Revision based diagnosis was good (Cohen’s k =. There was high convergent validity with the Beck Depression Inventory (r =. 875) and internal consistency (Cronbach’s a =. In addition to good content validity, PHQ-9 had good 1-month test-retest reliability (r =. A PHQ-9 score of 5 was ideal for screening (sensitivity, 87.1% specificity, 79.7%). Results indicate a total of 31 students (13.3%) had a form of depression on psychiatric interview. This article discusses the diagnostic accuracy, reliability, and validity of the Patient Health Questionnaire - 9 ( PHQ-9) when pediatricians use it among Indian adolescents. Participants - 233 adolescent students aged 14 to18 years Patient Health Questionnaire-9 as an effective tool for screening of depression among Indian adolescents.
