TL;DR: The combination was estimated to reduce the number of participants needing to complete the full PHQ-9 by 57% (56%-58%) and to understand the clinical and research value of this combined approach to screening.

TL;DR: Sensitivity may be minimally reduced with the PHQ-8, but specificity is similar, and bivariate random-effects models to assess diagnostic accuracy were similar.

TL;DR: PHQ-9 ≥ 10 substantially overestimates depression prevalence because of too much heterogeneity to correct statistically in individual studies, and an alternative PHZ-9 cutoff could more accurately estimate prevalence.

TL;DR: An individual participant data meta-analysis is used to evaluate the accuracy of two PHQ-9 diagnostic algorithms for detecting major depression and compare accuracy between the algorithms and the standard PHZ-9 cutoff score of ≥10.
