121 Dialectical behavior therapy and cognitive behavior therapy in individuals with binge eating disorder: what works for whom? 5 Moderators. Four significant moderators were found at EOT. Overvaluation of weight and shape was a significant moderator of treatment (b = -0.480, SE(b) = .149, 95% CI(b) = -.771, -.188, p = .001, IRR = .619, 95% CI(IRR) = .462, .828) such that individuals with lower overvaluation had greater reductions in OBE frequency in CBT+ than DBT-BED, whereas differences between treatments were smaller for those with higher overvaluation. Similarly, shape concerns significantly moderated treatment (b = -.581, SE(b) = .167, 95% CI(b) = -.909, -.253, p = .001, IRR = .559, 95% CI(IRR) = .403, .776) such that individuals with low shape concern had greater reductions in OBE frequency in CBT+ than DBT-BED. Differences between treatments were smaller for those with higher shape concerns. Also, low self-esteem significantly moderated treatment EOT (b = -.108, SE(b) = .038, 95% CI(b) = -.181, -.034, p = .004, IRR = .898, 95% CI(IRR) = .834, .967). Individuals with higher self-esteem (meaning lower scores on EDI-3 low self-esteem) showed greater reductions in CBT+ than DBT-BED, whereas differences between treatments were smaller for those with lower self-esteem. Finally, and similarly, emotional eating was a significant moderator of treatment (b = -1.185, SE(b) = .390, 95% CI(b) = -1.949, -.421, p = .002, IRR = .3.270, 95% CI(IRR) = 1.523, 7.019) such that individuals with lower emotional eating experienced greater reductions in OBE frequency in CBT+ than in DBT-BED. Yet, individuals with the highest emotional eating scores showed more decrease in OBE episodes with DBT-BED than with CBT+. No significant results were found at EOT for dietary restraint, weight concerns, emotion dysregulation, difficulty identifying feelings, depressive symptoms and anxiety. Six-month follow-up Predictors. Smaller reductions in OBE frequency at six-month follow-up were predicted by greater difficulty in identifying feelings (b = .081, SE(b) = .032, 95% CI(b) = .019, .143, p = .011, IRR = .1.084, 95% CI(IRR) = 1.019, 1.154), higher depressive symptoms (b = .037, SE(b) = .013, 95% CI(b) = .010, .063, p = .006, IRR = 1.037, 95% CI(IRR) = 1.011, 1.065), and higher emotional eating (b = .846, SE(b) = .308, 95% CI(b) = .242, 1.499, p = .006, IRR = 2.330, 95% CI(IRR) = 1.274, 4.261) at baseline. Other predictors were non-significant. Moderators. Only one variable was a significant moderator of treatment at six-month follow-up. Difficulty in identifying feelings significantly moderated treatment (b = -.259, SE(b) = .054, 95% CI(b) = -.365, -.153, p < .001, IRR = .772, 95% CI(IRR) = .694, .858) such that individuals with less difficulties in identifying feelings showed greater reductions in CBT+ than DBT-BED, whereas those with the most difficulties in identifying feelings had greater reductions in DBT-BED.
