Estimation of the Minimal Clinically Important Difference (MCID)
Depression
The MCID for all outcome measures was calculated using the standard error of measurement (SEM):Sigma (BADS MCID change from Time 1 to Time 2 between groups using complete cases (including those re-randomised) are in Fig. Visualisations of participant-level change scores from Time 1 to Time 2 on the Behavioural Activation for Depression Scale (BADS), not including those who withdrew. Dashed lines indicate the minimal clinically important difference (8.28) in either direction. Higher change scores indicate greater improvements in activity levels. Percentages indicate numbers of those within in each group who made MCID improvements on the BADS from Time 1 to Time 2As shown in Fig.
