An individual patient data meta-analysis investigating the minimal detectable change for the PHQ-9, PHQ-8, and PHQ-2 depression screening questionnaires. The dataset, authored by Yutong Wang and harvested from Borealis Dataverse, was last updated in April 2026. It examines how measurement thresholds vary by participant characteristics and study-level variables.
Use Cases
- Establishing clinically significant change thresholds for depression screening based on meta-analysis results.
- Comparing measurement error and sensitivity across PHQ-9, PHQ-8, and PHQ-2 versions.
- Modeling how minimal detectable change varies with patient demographics and study design.
Strengths
- Focuses on a clinically significant metric (minimal detectable change) for widely-used depression scales.
- Analysis includes three common questionnaire versions (PHQ-9, PHQ-8, PHQ-2).
- Examines variation by participant characteristics and study-level variables.
Limitations
- Row count and specific column-level documentation are unknown, requiring inspection after download.
- Description metadata is limited; actual data structure and completeness require manual verification.
