Structure of the PHQ-9 Questionnaire
The PHQ-9 is a 9-item questionnaire assessing depression symptoms over the past two weeks․ Each item uses a 4-point Likert scale (0-3), measuring symptom frequency and severity․ It is self-administered, concise, and widely used in clinical and research settings to evaluate depressive disorders effectively․
Key Components of the PHQ-9
The PHQ-9 consists of 9 items assessing depression symptoms over the past two weeks․ Each item is rated on a 4-point scale (0-3), reflecting symptom frequency and severity․ The questionnaire includes questions about interest in activities, feelings of depression, sleep disturbances, fatigue, appetite changes, feelings of worthlessness, concentration difficulties, and suicidal thoughts․ Item 9 specifically evaluates suicidal ideation, requiring immediate follow-up if scored as “3․” The total score ranges from 0 to 27, categorizing depression severity as mild (0-5), moderate (6-10), moderately severe (11-15), or severe (16-27)․ This structure ensures a comprehensive evaluation of depressive symptoms, aiding in diagnosis and treatment planning․
How to Administer the PHQ-9
Administering the PHQ-9 involves providing clear instructions to participants․ Ensure they understand the 4-point scale (0-3) for rating symptom frequency over the past two weeks․ Emphasize the importance of honest responses․ The questionnaire should be completed independently, but assistance is allowed for those with literacy or cognitive challenges․ Special attention must be given to item 9, which assesses suicidal ideation․ If a participant scores “3” on item 9, immediate follow-up is required within one hour to ensure safety․ Inform participants that their responses are confidential and that follow-up may occur if safety concerns arise․ This ensures ethical administration and appropriate care for individuals with concerning symptoms․
Scoring and Interpretation of GAD-7 and PHQ-9
The GAD-7 and PHQ-9 are scored by summing responses, with higher scores indicating greater symptom severity․ For PHQ-9, scores range from 0-20, categorizing depression as mild (0-5), moderate (6-10), moderately severe (11-15), or severe (16-20)․ The GAD-7 scores range from 0-21, with thresholds for mild (0-4), moderate (5-9), and severe (10-21) anxiety․ These standardized scoring systems enable consistent interpretation and clinical decision-making․
Scoring Criteria for GAD-7
The GAD-7 scoring system evaluates anxiety severity by summing responses to its 7 items․ Each item is rated on a scale of 0 (not at all) to 3 (nearly every day), with total scores ranging from 0 to 21․ The thresholds for interpretation are as follows:
– 0-4 points: Minimal anxiety symptoms․
– 5-9 points: Mild anxiety․
– 10-14 points: Moderate to moderately severe anxiety․
– 15-21 points: Severe anxiety․
These scores help clinicians diagnose generalized anxiety disorder and monitor treatment progress․ Higher scores indicate greater symptom severity and potential need for intervention․ The GAD-7 is widely used for its simplicity and reliability in assessing anxiety levels in clinical and research settings․
Scoring Criteria for PHQ-9
The PHQ-9 is a 9-item questionnaire assessing depression severity․ Each item is scored from 0 (not at all) to 3 (nearly every day), with total scores ranging from 0 to 27․ The scoring thresholds are as follows:
