Differential change was calculated as the difference in change from baseline for the intervention versus change from baseline for the comparison group. The differing numbers of individuals included in each outcome analysis is due to the AQOL allowing for differing numbers of missing responses for each subscale.
HLC, healthy living course; MBSR, mindfulness-based stress reduction.
