This study aimed to evaluate the effectiveness of a multidisciplinary parent training program, Promoting Holistic Development of Young Kids (Poly Kids), using a single-blind randomized waitlist controlled design. The participants included 218 parents of children with developmental disabilities (DD) (intervention group = 107 and waitlist control group = 111). The primary outcomes were child learning, expressive language, fine and gross motor skills (based on individual assessment by respective blinded professionals), and parental reports of child behavior problems. The parents in the intervention group reported significantly lower child behavior problems (d =.34), higher child task motivation (d =.63), and lower parenting stress post-intervention (d =.25), while the children in the intervention group produced significantly more words post-intervention (d =.82). McNemar test results were significant for movement out of the clinical range in child behavior problems and cognitive skills in the intervention group, but not the control group. The results provided initial evidence on the effectiveness of this train-the-trainer program in supporting families with preschool children with DD in terms of child behavior problems, expressive language, cognitive skills, task motivation, and parenting stress.
