Using the MHP reinterview as the criterion standard, a PHQ-9 score 鈮 10 had a sensitivity of 88% and a specificity of 88% for major depression. PHQ-9 scores of 5, 10, 15, and 20 represented mild, moderate, moderately sev...
This differed from a meta-analysis of PHQ-9 individual participant data,20 in which, among studies that used a semistructured interview, sensitivity at the standard cutoff score of 10 or greater was substantially greater than reported in a previous aggregate-data meta-analysis that combined ...
The continuous measure is a summary score ranging from 0 to 27 and is calculated by adding up the re- sponses to the nine questions, which allows assessing the presence and severity of a depressive episode [24]. The initial cut-off points proposed by the authors for the US population ...
The total score is used to evaluate the individual's emotional state: - 0-4 points: Normal emotional state - 5-9 points: Mild depression - 10-14 points: Moderate depression - 15-19 points: Moderately severe depression - 20-27 points: Severe depression During the assessment, the individual ...
The accuracy of the PHQ-9 was evaluated in 31 (74%) studies with a two-stage screening system, with structured interview most often carried out by primary care and mental health professionals. Most of the studies employed a cut-off score of 10 (N=24, 57%, total range 5 – 15). The...

2) missing values at follow-up were replaced with the mean item values of the patient sample with complete values; 3) the mean difference score of the 5% of patients with the lowest PHQ-9 difference scores was used to estimate the PHQ-9 sum score of the patients with missing values at ...
The PHQ-9 and in-depth interviews were used at the same three time points over a 6-month period during a new or first episode of depression. RESULTS: Patterns in the total PHQ-9 score broadly reflected patients' accounts of the severity of their depression over time. However, the PHQ-9...
Finally, a logistic regression model revealed that only one factor of self-perceived health status (fair/poor vs. excellent/very good, OR=7.519, 95% CI=3.03–18.68, p<0.001) exhibited a statistically significant correlation with depressive symptom occurrence (PHQ-9 score≧10) among the ...
Major depressive disorder (MDD) may be present in 10%–20% of patients in medical settings. Routine depression screening is sometimes recommended to improve depression management. However, studies of the diagnostic accuracy of depression screening tools
