Note. For within-group and between-group comparisons, post-intervention was compared to baseline and 6-months post was compared to baseline for each variable. Abbreviations: PHQ-8 = 8-item Patient Health Questionnaire depression scale (range, 0–24). GAD-7 = 7-item Generalized Anxiety Disorder anxiety scale (range, 0–21). ISI = Insomnia Severity Index (range, 0–28). PEG = 3-item abbreviated version of Brief Pain Inventory (range 0–10). SD=standard deviation. SRM= standardized response mean. CI=confidence interval. d=Cohen’s d effect size. Significant p-values are designated as follows:
