Trajectory of symptoms over time.

Figure 2a. Anxiety symptoms over time in MBSR and Health Education groups.

Figure 2c. Sleep symptoms over time in MBSR and Health Education groups Means (± SE) over time for STAI (anxiety), CESD (depression) and PSQI (sleep) scales are plotted for the MBSR and Health Education (HE) groups in the intention-to-treat sample after Randomization 2, without imputation of missing values (MBSR, n=63; HE, N=59). Asterisks indicate significant between group differences: the MBSR group reported fewer symptoms of poor sleep and anxiety over time (Ps=0.02, both) than the Health Education group. The difference between groups in depression trajectories was not significant (P=0.10). Values were calculated using linear mixed models with adjustments for baseline value, course cycle, randomization strata, prior waitlist service, interaction between time and treatment impact, and intra-correlations among repeated measurements within subjects and among subjects within a course cycle.
