The Association between Early Adherence and Post-treatment OCD Severity

Sample	Predictors	β	95% CI	p value	sr²
Intent-to-treat
	Baseline Y-BOCS	0.33	(−0.24, 0.91)	.246	.02
	Early mean adherence	−3.82	(−5.56, −2.08)	<.001	.29
	Early change of adherence	−3.16^*	(−5.45,−0.87)	.009	.11
Completer
	Baseline Y-BOCS	0.36	(−0.40, 1.12)	.340	.03
	Early mean adherence	−4.17	(−7.49, −0.85)	.016	.20
	Early change of adherence	−3.58^*	(−7.07, −0.09)	.045	.13

Note. CI, confidence interval; sr², the semi-partial correlation is a measure of the unique variance explained by each predictor and it is equivalent to the R² change in a step-wise model when each predictor is entered separately; Y-BOCS, Yale-Brown Obsessive Compulsive Scale score.

Standardized coefficient of early change of adherence, i.e., 1 sd unit increase of early change of adherence corresponds to β points change in post-treatment Y-BOCS.
