Order A‐B (n = 34 rrMDD; n = 22 HC) |
DAS Mean (SD) | 117.9 (32.5) | 116.8 (31.9) | −1.16 (10.5) | 97.2 (17.4) | 103.1 (19.7) | 5.96 (11.5) | .083 |

Order B‐A (n = 28 rrMDD; n = 20 HC) |
DAS Mean (SD) | 115.9 (20.7) | 126.6 (27.3) | 10.6 (19.0) | 106.7 (25.0) | 109.3 (22.4) | 2.68 (10.7) | .064 |

A‐B = participants who filled in the DAS‐A before MIP and BAS‐B after MIP; B‐A = participants who filled in the DAS‐B before MIP and BAS‐A after MIP; DAS = Dysfunctional Attitudes Scale; HC = healthy controls; MIP = mood‐induction procedure; rrMDD = remitted recurrent major depressive disorder; SD = standard deviation; p = p‐value.
Group differences in VAS change scores did not significantly change when correcting for HDRS scores. Bold: significant within‐group difference in remitted MDD for the A‐B sequence versus B‐A sequence (p = .003).
