The PHQ-9 asks how often respondents have been bothered by problems in the last 2 weeks. Items are rated on a 4-point Likert-type scale, ranging from 0 (not at all) to 3 (nearly every day). Total score can range from 0 to 27, with high scores meaning high depression. Based on ...
Meaning PHQ-2 followed by PHQ-9 may provide acceptable accuracy for screening for depression. Abstract Importance The Patient Health Questionnaire depression module (PHQ-9) is a 9-item self-administered instrument used for detecting depression and assessing severity of depression. The Patient Health Qu...
The first residual dimension is usually expected to have a value smaller than 2.0, which has been shown to happen entirely due to random variation.49 In addition, fit statistics <0.6 indicate items overfit the model, usually because they share some com ponents of meaning with other items....
[60,61]. To conduct the meta-analysis, we will seek primary datasets that allow us to compare PHQ-9 scores to MDD or major depressive episode (MDE) diagnostic status. Most primary studies use MDD as the reference standard, but some may use MDE, which is identical with respect to the ...
Multivariate linear regression revealed a negative correlation between WA and depression severity based on PHQ-9 scores (beta = -0.4, P < 0.05). Conclusions: A negative correlation exists between absolute and relative WA and depression severity, meaning, with the higher severity of depression the ...
