Results of “As-Treated” Analyses.

	Change from baseline				AMP attendance regression coefficient predicting change, adjusting for site
	Attended AMP (n = 60)		No class (n = 46)
Outcome	n	Unadjusted mean [95% CI]	n	Unadjusted mean [95% CI]	b [95% CI]	p
Quality of life	56	0.6 [−1.2, 2.5]	42	−0.5 [−3.0, 1.9]	1.1 [−2.0, 4.1]	.49
Physical health	60	0.7 [−1.3, 2.7]	46	−0.8 [−3.2, 1.6]	1.4 [−1.8, 4.5]	.39
Mental health	60	2.3 [0.8, 3.9]	46	−1.2 [−3.4, 1.0]	3.6 [1.0, 6.2]	.007
PAM score	56	1.1 [−3.2, 5.4]	42	1.0 [−3.3, 5.3]	0.6 [−5.8, 7.0]	.86
PAM level	56	0.1 [−0.1, 0.3]	42	0.1 [−0.2, 0.3]	0.02 [−0.3, 0.3]	.92

Note. AMP = Aging Mastery Program; PAM = Patient Activation Measure. Only includes the four sites that had control groups (Sites A-D). Of the 70 who attended AMP, 60 completed at least one outcome at postassessment, while of the 79 who attended no AMP classes, 46 completed at least one outcome at postassessment. Boldfaced results have 95% confidence intervals that do not include zero, which indicates a statistically significant increase in the outcome from baseline.
