Results are for individuals with BDI-II scores of at least 16, except where noted. Regression models used endorsement of biochemical/genetic attributions and/or BDI-II score as independent predictors. The number of subjects varies slightly in each of the study 2 regressions reported above because some participants did not respond to all measures.
