Three-way analysis of variance in electrodermal activity (EDA) controlling for EDA at baseline

Effect	F	$\mathit{d}{\mathit{f}}_{\mathbf{1}}^{\mathit{\text{GG}}}$	$\mathit{d}{\mathit{f}}_{\mathbf{2}}^{\mathit{\text{GG}}}$	MSE	p	${\widehat{\mathit{\eta }}}_{\mathit{G}}^{\mathbf{2}}$
Baseline EDA at Time 1 (control)	166.34	1	50	11.65	< .001	.642
Condition	1.34	2	50	11.65	.271	.028
Social Anxiety	0.36	1	50	11.65	.549	.004
Time	81.01	3.38	169.14	2.96	< .001	.428
Condition × Social Anxiety	1.32	2	50	11.65	.276	.028
Baseline EDA × Time	1.72	3.38	169.14	2.96	.158	.016
Condition × Time	0.84	6.77	169.14	2.96	.549	.015
Social Anxiety × Time	1.40	3.38	169.14	2.96	.242	.013
Condition × Social Anxiety × Time	1.18	6.77	169.14	2.96	.319	.021

Note: Social anxiety was a centered continuous predictor. As reflected by the GG superscripts, non-integer degrees of freedom reflect Greenhouse-Geisser corrections for departure from sphericity. MSE = mean squared error; ${\widehat{\eta }}_G^2$ = generalized eta-squared
