Evaluation of a cluster-randomized controlled trial: Communities for Healthy Living, family-centered obesity prevention program for Head Start parents and children

Table 7 Secondary outcomes (parents). Mean parental empowerment and parenting scores by timepoint, absolute change across semesters, and modeled relative mean change among parents exposed to intervention vs. control

	Mean (SD) values by timepoint		Mean (SD) values by timepoint		Estimated change in outcome (Intervention vs. control)
	Control (n = 454)		Intervention (n = 501)		Model 3.1 ^a,b	Model 3.2 ^a,c
	Baseline	Change	Baseline	Change	Unadjusted	Adjusted
Empowerment	3.2 (0.41)	0.02 (0.50)	3.2 (0.40)	0.05 (0.40)	0.04 (−0.02, 0.11)	0.05 (−0.02, 0.11)
Parenting	3.0 (0.40)	−0.02 (0.37)	3.0 (0.40)	0.05 (0.36)	0.05 (−0.003, 0.11)	0.06 (0.00, 0.12)

^a Stars indicate significance *p ≤ 0.05, **p ≤ 0.01, ***p ≤ 0.001
^b Results from an unadjusted linear mixed effects regression model; shown is the mean unadjusted change (95% confidence interval) in outcomes for parents exposed to intervention relative to control
^c Results from a linear mixed effects regression model, adjusting for parent race and ethnicity, educational attainment, and household employment status; shown is the mean adjusted change (95% confidence interval) in outcomes for parents exposed to intervention relative to control
