Results of Intention-to-Treat Analyses.

	Change from baseline				AMP regression coefficient predicting change, adjusting for site

Quality of life	35	0.2 [−2.0, 2.4]	28	0.8 [−2.6, 4.2]	−0.6 [−4.5, 3.3]	.77
Physical health	39	0.3 [−2.1, 2.7]	32	0.4 [−3.2, 3.9]	−0.1 [−4.2, 4.0]	.97
Mental health	39	2.1 [0.02, 4.1]	32	−0.8 [−3.7, 2.1]	2.8 [−0.6, 6.3]	.10
PAM score	37	2.5 [−2.4, 7.4]	27	0.3 [−4.7, 5.4]	2.4 [−4.7, 9.5]	.50
PAM level	37	0.2 [−0.1, 0.4]	27	−0.04 [−0.3, 0.2]	0.2 [−0.1, 0.5]	.24

Note. AMP = Aging Mastery Program; PAM = Patient Activation Measure. Only includes the three sites that allowed random assignment (A-C). Analyses are based on assigned condition, not actual exposure (12 assigned to control attended AMP; 18 assigned to AMP attended no classes). There were 39 in the treatment condition who completed at least one outcome at postassessment (out of 56 who were randomized to the treatment arm) and 32 in the wait-list control who completed at least one outcome at post-assessment (out of 53 who were assigned to the waitlist arm). Boldfaced results have 95% confidence intervals that do not include zero, which indicates a statistically significant increase in the outcome from baseline.
