報告內容
We implemented a non-masked, cluster-randomized controlled trial in rural areas of Northwestern China. All children aged 18–30 months in 131 villages of four randomly selected underdeveloped counties were enrolled in November 2014. We randomly assigned villages to treatment (65 villages, 213 caregiver-child dyads) or control (66 villages, 379 caregiver-child dyads) groups. In the intervention group, caregiver-child dyads were involved in weekly home visits focusing on psychosocial stimulation of young children over the period of 6 months. The control group received no home visits. Approximately 7.5 years after program completion, when children were 9–10 years old, follow-up data were collected (N = 466). Intention-to-treat (ITT) effects show that the intervention led to an improvement in Wechsler Intelligence Scale for Children full-scale IQ, verbal comprehension index, and processing speed index scores (standardized effect sizes of 0.18 SD [95% CI 0.00 SD–0.37 SD]; 0.29 SD [95% CI 0.09–0.48]; and 0.21 SD [95% CI 0.03–0.39], respectively). Furthermore, we find evidence of sustained improvements in children’s learning outcomes and environment. Our results demonstrate that program with sustained impacts on children’s learning environment can lead to lasting medium-term gains in child development.
