Abstract Introduction: The Patient Health Questionnaire-9 (PHQ-9) is a brief screening and diagnostic tool for depression. It has been used in research and clinical practice in primary care and other clinical and non-clinical settings. The PHQ-9 has not had its validity examined in psychiatric and psychological settings in Iran. Methods: A cross-sectional study was conducted to investigate the validation of the Farsi version of the PHQ-9. A convenience sample of 130 Iranian volunteer psychiatric outpatients was selected from psychiatric and psychological clinics. They completed the PHQ-9, the Patient Health Questionnaire-15 (PHQ-15), the World Health Organization-five Well-Being Index (WHO-5), and the short form of the Beck Depression Inventory-13 (BDI-13). Data were analyzed by descriptive statistics, Cronbach's α, Pearson correlation coefficient, principal component analysis, exploratory factor analysis, and confirmatory factor analysis. Results: Mean score of the PHQ-9 was 12.83 (standard deviation = 6.25), indicating moderately severe depression in the sample. Cronbach's α coefficient for PHQ-9 was 0.88, and one-week test-retest reliability 0.79. The PHQ-9 correlated 0.64 with PHQ-15, −0.35 with WHO-5, and 0.70 with BDI-13, indicating good construct and criterion-related validity. The results of the factor analysis of PHQ-9 items identified and confirmatory factor analysis confirmed a single factor labeled general depression. Conclusions: The PHQ-9 appears to have a unidimensional structure, adequate validity and reliability, and can be useful in epidemiological/research settings. Based on previous literature and on the present findings, the PHQ-9 may have applicability to other contexts in the studied population, but this needs to be confirmed by other studies.

Abstract Background: Much of the research about the validity of depression screening questionnaires is on criterion validity. Evidence is scarce on the concurrent, convergent and construct validity of these measures, particularly from low-income countries. This study aimed to evaluate the psychometric properties of depression screening questionnaires in primary healthcare (PHC) in rural Ethiopia. Methods: A facility-based cross-sectional study was conducted with 587 participants recruited from patients attending three PHC facilities and two Holy water sites. The psychometric properties of five mental health screening questionnaires were evaluated: the nine item Patient Health Questionnaire (PHQ-9), the two item version of PHQ-9 (PHQ-2), a version of PHQ-9 with two added items of irritability and noise intolerance (PHQ-11), the Patient Health Questionnaire-15 (PHQ-15), and the World Health Organization-Five Well-being Index (WHO-5). Clinical diagnosis of depression was ascertained by psychiatrists using a semi-structured interview. We analyzed data using exploratory factor analysis, Spearman’s rank order correlation coefficient (Rho), the Mann Whitney test of the equality of medians, univariate logistic regression and Cronbach’s alpha. Results: PHQ-9, PHQ-11 and WHO-5 were found to be unidimensional, with items in each scale highly loading onto one factor (factor loadings ranging from 0.64 to 0.87). The items of each instrument were internally consistent, with Cronbach’s alpha ranging from 0.72 (PHQ-2) to 0.89 (PHQ-11). Scores for all screening scales were moderately or highly correlated with each other (Rho= 0.58 to 0.98) and moderately correlated with anxiety and disability scores. Median scores of all screening scales were significantly higher in those diagnosed with depression. The association of items measuring emotional and cognitive symptoms with the diagnosis of depression was stronger than the association with items measuring somatic symptoms. Irritability and noise intolerance had higher association with depression diagnosis than PHQ-9 items. Conclusion: Emotional and cognitive symptoms are more useful than somatic symptoms to predict the diagnosis of depression. Irritability and noise intolerance are more useful to detect depression. Future research should focus on testing the unidimensionality of PHQ-9, PHQ-11 and WHO-5 using confirmatory factor analysis; establishing the criterion validity of PHQ-11 and WHO-5; and on assessing test-retest reliability of all the measures.

AbstractBackgroundDepression affects approximately 25% of people with MS (pwMS) at any given time. It is however under recognised in clinical practice, in part due to a lack of uptake for brief assessment tools and uncertainty about their psychometric properties. The 9-item Patient Health Questionnaire (PHQ-9) is an attractive candidate for this role.ObjectiveTo synthesise published findings on the psychometric properties of the 9-item Patient Health Questionnaire (PHQ-9) when applied to people with multiple sclerosis (pwMS).Data sourcesPubMed, Medline and ISI Web of Science databases, supplemented by hand-searching of references from all eligible sources.Study eligibility criteriaPrimary literature written in English and published following peer-review with a primary aim to evaluate the performance of the PHQ-9 in pwMS.Outcome measuresPsychometric performance with respect to appropriateness, reliability, validity, responsiveness, precision, interpretability, acceptability, and feasibility.ResultsSeven relevant studies were identified, these were of high quality and included 5080 participants from all MS disease-course groups. Strong evidence was found supporting the validity of the PHQ-9 as a unidimensional measure of depression. Used as a screening tool for major depressive disorder (MDD) with a cut-point of 11, sensitivity was 95% sensitivity and specificity 88.3% (PPV 51.4%, NPV 48.6%). Alternative scoring systems that may address the issue of overlap between somatic features of depression and features of MS per se are being developed, although their utility remains unclear. However data on reliability was limited, and no specific evidence was available on test-retest reliability, responsiveness, acceptability, or feasibility.ConclusionsThe PHQ-9 represents a suitable tool to screen for MDD in pwMS. However use as a diagnostic tool cannot currently be recommended, and the potential value for monitoring depressive symptoms cannot be established without further evidence on test-retest reliability, responsiveness, acceptability, and feasibility.PROSPERO register ID: CRD42017067814

Background. To create efficacious interventions for military family caregivers (MFCs), it is important to understand the characteristics and predictors of completers and dropouts of newly developed supportive interventions. Aim. The purpose of this study was to examine completion patterns in MFCs enrolled in an educational intervention feasibility study. Method. Baseline data are presented from MFC completers ( n = 64) and dropouts ( n = 60) of a national feasibility study for an innovative intervention. Measures include depression (Patient Health Questionnaire–2), anxiety (Generalized Anxiety Disorder–7), somatic symptoms (Patient Health Questionnaire–15), quality of life (World Health Organization Quality of Life–Brief), relationship satisfaction (Relationship Assessment Scale), and military care recipient number of injuries. Analysis of variance was used to evaluate differences between completers and dropouts and logistic regression was used to identify predictors of intervention completion. Results. Results indicated that MFCs with greater anxiety, χ2(3) = 10.33, p = .02; depression, χ2(1) = 8.18, p = .004; somatic symptoms, F(1, 106) = 6.26, p = .01; care recipient number of injuries, F(1, 118) = 16.31, p < .001; lower general satisfaction with treatment, F(1, 96) = 4.34, p = .04; and lower satisfaction with accessibility and convenience with treatment, F(1, 89) = 4.18, p = .04, were significantly more likely to complete the intervention. After multivariate analysis, the sole predictor of intervention completion was the number of care recipients’ injuries, χ2(6) = 14.89, N = 77, p < .05. Conclusions. Overall, findings indicate that MFCs who were more “at risk” were more likely to complete the intervention. Findings present patterns of intervention completion and provide insight on areas in need of further investigation on intervention development supporting the needs of MFCs.
