|---|---|---|---|---|---|---|
| D-MCT (n = 41) | HT (n = 43) | t test | D-MCT (n = 41) | HT (n = 43) | ANCOVAa | |
| MCQ (PB) | 13.23 (4.16) | 12.76 (3.64) | t(82) = 0.558, p = 0.578 | 11.43 (2.85) | 13.05 (3.51) | F(1, 81) = 12.041, p = 0.001, ηp 2 = 0.129 |
| MCQ (NB) | 18.51 (3.98) | 17.24 (4.01) | t(82) = 1.465, p = 0.147 | 16.00 (3.93) | 17.28 (4.02) | F(1, 81) = 8.327, p = 0.005, ηp 2 = 0.093 |
| MCQ (NFC) | 14.12 (4.66) | 13.43 (3.26) | t(71.28) = 0.791, p = 0.432 | 11.94 (3.97) | 13.18 (4.37) | F(1, 81) = 11.445, p = 0.012, ηp 2 = 0.075 |
Note D-MCT = Metacognitive Training for Depression, HT = health training, MCQ (NB) = Metacognition Questionnaire, Negative Beliefs; MCQ (NFC) = Metacognition Questionnaire, Need for Control; MCQ (PB) = Metacognition Questionnaire, Positive Beliefs. a Difference scores (baseline to post) served as dependent variables; baseline scores were entered as a covariate. Effect sizes for ηp 2 refer to small (ηp 2 ≈ 0.01), medium (ηp 2 ≈ 0.06), and large (ηp 2 ≈ 0.14) effects, respectively.
