Abstract Background Depression in patients with infertility often goes undiagnosed and untreated. The Patient Health Questionnaire-9 (PHQ-9) and its ultra-brief version (i.e. PHQ-2) are widely used measures of depressive symptoms. These scales have not been validated in patients with infertility. The aim of the present study was to examine the reliability and validity of the PHQ-9 and PHQ-2 in patients with infertility. Methods In this cross-sectional study, a total of 539 patients with infertility from a referral infertility clinic in Tehran, Iran completed the PHQ-9, along with other relevant scales: the WHO-five Well-being Index (WHO-5), the Hospital Anxiety and Depression Scale (HADS), and the Generalized Anxiety Disorder-7 (GAD-7). Factor structure and internal consistency of PHQ-9 were examined via confirmatory factor analysis (CFA) and Cronbach’s alpha, respectively. Convergent validity was evaluated by relationship with WHO-5, HADS and GAD-7. Results The mean total PHQ-9 and PHQ-2 scores were 8.47 ± 6.17 and 2.42 ± 1.86, respectively, and using a cut-off value of 10 (for PHQ-9) and 3 (for PHQ-2), the prevalence of depressive symptoms was 38.6 and 43.6%, respectively. The Cronbach’s alphas for PHQ-9 and PHQ-2 were, respectively, 0.851 and 0.767, indicating good internal consistency. The CFA results confirmed the one-factor model of the PHQ-9 (χ2/df = 4.29; CFI = 0.98; RMSEA = 0.078 and SRMR = 0.044). Both PHQ-9 and PHQ-2 showed moderate to strong correlation with the measures of WHO-5, HADS-depression, HADS-anxiety, and the GAD-7, confirming convergent validity. In univariate analysis, female sex, long infertility duration, and unsuccessful treatment were significantly associated with depression symptoms. Conclusion Both PHQ-9 and PHQ-2 are brief and easy to use measures of depressive symptoms with good psychometric properties that appear suitable for routine use in patients with infertility.

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.

Depression is one of the most widely recognized and frequently underdiagnosed and undertreated mental health issues around the world. The Patient Health Questionnaire-9 (PHQ-9) has been suggested as the best accessible screening and case-discovering instrument to measure the severity of depression. The investigation aimed to set the reliability and validity of the PHQ-9 for the adults in Bangladesh. A total of 321 Bangladeshi adults (170 males and 151 females) were the study participants. A standard process of three phases was followed to adapt PHQ-9 in Bangladesh. The first phase was forward translation, second phase was Focus Group Discussion and panel of expert's rating and third phase was back translation into original language, piloting and final field data collection. The results showed good reliability of the translated version; the total scale Cronbach’s alpha is 0.837, gender-wise 0.839 for males and 0.841 is for females; similarly, the Spearman-Brown Coefficient is 0.855, and the Guttman Split-half coefficient is 0.848, which indicate the high Split-half reliability as well. The content and construct validity suggest that the Bangla PHQ-9 is a valid tool to assess the depression of Bangladeshi adults. Therefore, the Bangla version of PHQ-9 gives an impression of being a reliable and valid instrument to assess and diagnose depression among Bangladeshi people. Dhaka Univ. J. Biol.
