Generalized estimating equations predicting post-protocol parental knowledge scores as a function of informant (mother, adolescent), protocol condition (Setting-Sensitive Assessment, Control Assessment), and informant × condition interaction (n = 16)

Factor	Mean differences	B (SE)	95% CI	p
Main and interaction effects
Condition		−1.25 (2.33)		.59
Informant		−.37 (1.30)		.77
Condition × informant		4.06 (1.99)		.04
Planned comparisons
Mother versus adolescent report, Setting-Sensitive Assessment	3.68		[.59, 6.77]	.02
Mother versus adolescent report, Control Assessment	−.37		[−2.93, 2.18]	.77

B = Unstandardized beta; 95% CI = 95% Wald confidence interval. Factor contrasts based on comparisons in ascending order, with the Condition factor coded Setting-Sensitive Assessment (1) and Control Assessment (2) and the Informant factor coded mother (1) and adolescent (2). For statistical tests of planned comparisons, p values and 95% CIs reported reflect significance tests for the reported differences between means reported in Table 2
