Participants (<jats:italic>n<\/jats:italic>\u00a0=\u00a0161) were randomised to behavioural activation or guided self\u2010help and followed up for 12\u00a0months. Pre\u2010treatment variables were included if they have previously been shown to be associated with an increased risk of having depression in adults with IDs or have been reported as a potential predictor or moderator of outcome of treatment for depression with psychological therapies. The primary outcome measure, the Glasgow Depression Scale for Adults with Learning Disabilities (GDS\u2010LD), was used as the dependant variable in mixed effects regression analyses testing for predictors and moderators of outcome, with baseline GDS\u2010LD, treatment group, study centre and antidepressant use as fixed effects, and therapist as a random effect.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Higher baseline anxiety (mean difference in outcome associated with a 1 point increase in anxiety 0.164, 95% confidence interval [CI] 0.031, 0.297; <jats:italic>P<\/jats:italic>\u00a0=\u00a00.016), lower performance intelligence quotient (IQ) (mean difference in outcome associated with a 1 point increase in IQ 0.145, 95% CI 0.009, 0.280; <jats:italic>P<\/jats:italic>\u00a0=\u00a00.037) and hearing impairment (mean difference 3.449, 95% CI 0.466, 6.432; <jats:italic>P<\/jats:italic>\u00a0=\u00a00.024) were predictors of poorer outcomes, whilst greater severity of depressive symptoms at baseline (mean difference in outcome associated with 1 point increase in depression \u22120.160, 95% CI \u22120.806, \u22120.414; <jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.001), higher expectation of change (mean difference in outcome associated with a 1 point increase in expectation of change \u22121.013, 95% CI \u22121.711, \u22120.314; p 0.005) and greater percentage of therapy sessions attended (mean difference in outcome with 1 point increase in percentage of sessions attended \u22120.058, 95% CI \u22120.099, \u22120.016; <jats:italic>P<\/jats:italic>\u00a0=\u00a00.007) were predictors of more positive outcomes for treatment after adjusting for randomised group allocation. The final model included severity of depressive and anxiety symptoms, lower WASI performance IQ subscale, hearing impairment, higher expectation of change and percentage of therapy sessions attended and explained 35.3% of the variance in the total GDS\u2010LD score at 12\u00a0months (<jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup>\u00a0=\u00a00.353, <jats:italic>F<\/jats:italic><jats:sub>4, 128<\/jats:sub>\u00a0=\u00a017.24, <jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.001).
