Fixed and Random Effects for Three-Level Null Models Partitioning Variance in Adherence and Competence

Variable	Adherence			Competence
	Coefficient	95% CI	ICC	Coefficient	95% CI	ICC
Fixed effects
Intercept γ000	85.47**	[82.81, 88.13]		3.56	[3.44, 3.69]
Random effects
Residual εijk	99.32**	[81.27, 121.38]	0.67	0.22**	[0.18, 0.26]	0.54
Within therapist μ0jk	20.17*	[7.54, 53.99]	0.14	0.12**	[0.08, 0.17]	0.31
Between therapist μ00k	28.10**	[12.44, 63.45]	0.19	0.06*	[0.02, 0.15]	0.15

Note. Intraclass correlation (ICC) indicates proportion of variance in adherence/competence at each level. CI = confidence interval.
