The Patient Health Questionnaire-9 (PHQ-9) as a brief screening tool for depression: a study of Iranian college students

Adolescents with diabetes are at increased risk for depression and anxiety, which when untreated negatively affects diabetes control. During a 6-month period, the Patient Health Questionnaire for Depression and Anxiety (PHQ-4) screening tool was utilized. Those with a positive screen then completed the Patient Health Questionnaire for Adolescents (PHQ-A) and the Generalized Anxiety Disorder 7-item (GAD-7) scale. In this article, we report on the correlations in outcomes between the PHQ-4 and the PHQ-A and GAD-7 and its clinical utility for determining the need for standard versus acute behavioral health care. Over 6 months, 77 patients aged 10 to 18 years screened positive on the PHQ-4. Thirty-two patients had positive screening with the PHQ-A and/or the GAD-7. Thoughts of self-harm were reported by 13 (40%), with 1 experiencing current/active symptoms. The PHQ-4 as a screening tool was able to identify adolescents with symptoms of depression and/or anxiety who would benefit from further evaluation by a behavioral health provider.

Objective: To examine the reliability and validity of the Kessler 10 (K10) and the Patient Health Questionnaire (PHQ) in a sample of injecting drug users (IDUs). Method: Participants were 103 IDUs with a current substance use disorder accessing a needle and syringe programme. Presence of mental health disorders was assessed using the Mini International Neuropsychiatric Interview (MINI). Results: Both the K10 and PHQ had high levels of internal consistency and concurrent validity. Individuals with a positive screen on the K10 were ten lines more likely to have a current affective disorder, while those with a positive PHQ screen had nearly 14 times the risk. Conclusions: The K10 and PHQ are recommended as brief screening and diagnostic tools for current affective disorders among IDUs.

The present study examines a new factor structure and the convergent validity of the Portuguese version of the Patient Health Questionnaire-9 (PHQ-9) with college students. This measure has been used to evaluate depressive symptoms in adults. The total sample included 958 college students. Data were collected from a Web-based survey carried out in schools forming the Polytechnic Institute of Coimbra. Students completed the PHQ-9 and Hospital Anxiety and Depression Scale (HADS) and Brief Symptom Inventory (BSI) subscales as convergent measures. Results pointed to good fit of a second-order factor model with three first-order factors (somatic, cognitive and affective dimensions of depression). Strong positive correlations were found between PHQ-9 scores and HADS depression and BSI depression subscales. Our findings reinforce the PHQ-9 as a valid tool in higher education settings. Future studies should re-examine the dimensional structure of the tool considering its implications for the clinical interpretation of the measure.
