The isiXhosa PHQ-9 showed satisfactory criterion validity (area under the receiver operating characteristic curve, AUC = 0.706), but these analyses were under-powered. Principal component analysis revealed a one-factor solution, with 45.8% of variance explained by the first pri...
In the current research, the structure validity of the PHQ-9 was ana- lyzed by principal component analysis, and the results extracted three main factors contributing to a cumula- tive explained variance of 63.114%. The analysis of the three main factors was mainly related to low mood, lack...
Recently, item responses and total scores on depression screening scales have been reported to have characteristic distributions in the general population. The distributional pattern of responses to the Patient Health Questionnaire-9 (PHQ-9) in the general population has not been well studied. Thus, ...
Table 2. Distribution of PHQ scores and 12-month-CIDI Major Depressive Disorder (n = 897). 3.2. Reliability Values of the reliability coefficient Cronbach’s α for the PHQ-9 and PHQ-2 were 0.904 and 0.746, indicating acceptable reliability. For both PHQ forms, corrected item-total correlat...
Aim: The Patient Health Questionnaire (PHQ-9) is widely used for detecting and screening depression in Iraq. However, no psychometric assessment has been performed on any Iraqi version. This study aims at studying the reliability and validity of the Iraqi Kurdish version of the PHQ-9 as tool ...
respectively. The antenatal and postpartum data showed moderate correlations between both the EPDS and the PHQ-9 scores and the WHODAS scores (Spearman’s correlation coefficients = 0.53–0.66,p< 0.001). The EPDS and PHQ-9 were moderately accurate in distinguishing disability (WHODAS score ≥ ...
