Intervention effects on mother–child relationship and home environment measured by the HOME (intervention n = 30, control n = 32). (A) Generalized estimating equations models results had the following parameters for each HOME domain: emotional/verbal responsivity (coefficient = 0.97, 95% CI [0.37, 1.58], p = 0.002), avoidance of restriction and punishment (coefficient = 0.18, 95% CI [− 0.22, 0.59], p = 0.372), organization of the physical/temporal environment (coefficient = 0.14, 95% CI [− 0.20, 0.49], p = 0.406), provision of appropriate play materials (coefficient = 0.14, 95% CI [– 0.54, 0.82], p = 0.687), parental involvement with the child (coefficient = 0.28, 95% CI [– 0.06, 0.64], p = 0.110), opportunities for variety in daily stimulation (coefficient = 0.37, 95% CI [0.09, 0.66], p = 0.009). (B) Fitted models plots of all HOME domains over time by randomization status. Standardized effect sizes (Cohen’s d) were calculated from endpoint marginal means: emotional/verbal responsivity (d = 0.55), avoidance of restriction and punishment (d = 0.16), organization of the physical/temporal environment (d = 0.16), provision of appropriate play materials (d = 0.07), parental involvement with the child (d = 0.27), opportunities for variety in daily stimulation (d = 0.46).
