Caregiver skills training for caregivers of individuals with neurodevelopmental disorders: A systematic review and meta‐analysis.

Aim: To systematically review the effectiveness of caregiver and parent skills training programs, including caregiver‐mediated interventions, for caregivers of individuals with neurodevelopmental disorders. Method: We conducted a systematic review with a random‐effects meta‐analysis. We searched 11 electronic databases through July 2021 and used a snowball methodology to locate relevant articles of randomized controlled trials. Effect size estimates were pooled using Hedges' g from data extracted from study reports and through author requests using random‐effects meta‐analyses for three child outcome categories (child development, adaptive behavior, and problem behavior) and three caregiver outcome categories (parenting skills and knowledge, psychological well‐being, and interpersonal family relations). Results: We located 44 910 records, from which 75 randomized controlled trials involving 4746 individuals with neurodevelopmental disorders and their caregivers were included. Random‐effects meta‐analyses showed improvements in child development (g = 0.30; 99% confidence interval [CI] = 0.07–0.53) and reduction in reported problem behaviors (g = 0.41; 99% CI = 0.24–0.59), but not a statistically significant improvement in adaptive behavior (g = 0.28; 99% CI = −0.42 to 0.98). Caregivers showed improvements in parenting skills and knowledge (g = 0.72; 99% CI = 0.53–0.90), psychological well‐being (g = 0.52; 99% CI = 0.34–0.71), and interpersonal family relations (g = 0.76; 99% CI = 0.32–1.20). Interpretation: Caregiver skills training programs benefit both caregivers and children with neurodevelopmental disorders. Skills training programs improve child development and behavior, improve parenting skills, reduce caregiver mental health issues, and improve family functioning. Programs using culturally appropriate training material to improve the development, functioning, and participation of children within families and communities should be considered when caring for children with neurodevelopmental disorders. What this paper adds: Caregiver skills training programs are effective interventions for both caregivers and children.Children with neurodevelopmental disorders benefit from improvements in development and reduction of problematic behaviors.Caregivers benefit from enhanced skills and psychological well‐being.Improvements in interpersonal family relationships have also been documented.
