Results of the statistics for the questionnaire data: (a) the interaction of the 2 × 2 (group by time) rmANOVA; (b) values at pre and post for the MBSR group and results of a paired-samples t-test; (c) values at pre and post for the control group and results of a paired-samples t-test; (d) baseline differences between the MBSR and control groups.
