The Patient Health Questionnaire (PHQ) and GAD-7 offer clinicians concise, self-administered screening and diagnostic tools for mental health disorders
PHQ-9 scoring The PHQ-9 consists of nine questions that ask respondents how often they’ve “been bothered by any of the following problems” in the past two weeks. The questions address sleep, energy, appetite, and other possible symptoms of depression. Scores are calculated based on how fr...
The structure of the PHQ-9 is notably concise, which allows for quick administration and scoring. Each item is rated on a four-point scale from “not at all” to “nearly every day,” making it possible for healthcare providers to quantify the severity of depression based on cumulative scor...
There was substantial heterogeneity (Diagnostic Odds Ratio heterogeneity I2=82%), which was not explained by study setting (primary care versus general hospital); method of scoring (cutoff ≥10 versus "diagnostic algorithm"); or study quality (blinded versus unblind...

This review shows that, if the algorithm scoring method is used, the PHQ-9 has a low sensitivity for detecting MDD. This could be due to the rating scale categories of the measure, higher specificity or other factors that warrant further research. The summed-item score method at proposed cut...
The scoring sheet includes nine questions, and each question has four answer options (0-3 points). The individual being assessed selects the answer that best reflects their own situation. The scores for each question are then summed up, resulting in a total score ranging from 0 to 27. The...
The PHQ-9 is a short, self-administered questionnaire, widely used for screening of depression in primary care settings [14], and detection of this condition in large epi- demiological studies [15–18]. Because this instrument is based on DSM- IV criteria, those scoring high are often ...
