Group Differences between the BPT and the EP Group for Change Scores between t0 and t1
| BPT (n = 64) | EP (n = 69) | Cohen’s d | Independent t-test | U-test | |
|---|---|---|---|---|---|
| Scale | ∆M (SD) | ∆M (SD) | p | p | |
| Primary outcome | |||||
| Depression (MADRS) | −8.4 (10.4)+ | −3.0 (9.3)+ | 0.55 | .002* | .001* |
| Secondary outcomes | |||||
| Anxiety (GAD-7) | −3.4 (4.3)+ | −2.0 (4.0)+ | 0.35 | .046* | .079† |
| Body Image (FKB-20) | 3.5 (6.6)+ | 1.0 (5.3) | 0.42 | .018* | .010* |

| Depression (PHQ-9) | −4.7 (6.3)+ | −2.6 (5.2)+ | 0.36 | .041* | .043* |
Note. Differences between t0 and t1 (t1-t0): Negative values on the MADRS, PHQ-9, GAD-7, and SCL-90 indicate improvements in symptoms, positive values on the FKB-20, GSE, R-SES, and FERUS indicate positive effects
+ indicates a significant difference between t0 and t1 within the group; †p ≤ .10; * p ≤ .05
