Statistical Analysis
For statistical power considerations, an RCT of a similar program, Mindfulness-Based College, demonstrated a between-group MAIA scale effect size (SD) of 0.63 (0.83).We used generalized estimating equations to evaluate the effects of the MB-BP program on outcomes compared with the control program at 3 and 6 months using an identity link and autoregressive covariance structure. Unadjusted analyses were prespecified due to risks for covariate adjustment making models less precise and inducing bias.Analyses were performed from June 1, 2022, to August 30, 2023, using intention-to-treat principles. We analyzed all participants with data regardless of whether they completed the MB-BP or control program, detailed elsewhere.
