A key challenge in developing countries interested in providing early childhood development programs at scale is whether these programs can be effectively delivered through existing public service infrastructures. We present the results of a randomized experiment evaluating the effects of a home-based parenting program delivered by cadres in China’s Family Planning Commission (FPC) - the former enforcers of the one-child policy. We find that the program significantly increased infant skill development after six months and that increased investments by caregivers alongside improvements in parenting skills were a major mechanism through which this occurred. Children who lagged behind in their cognitive development and received little parental investment at the onset of the intervention benefited most from the program. Household participation in the program was associated with the degree to which participants had a favorable view of the FPC, which also increased due to the program.
IntroductionInadequate care during early childhood can lead to long-term deficits in skills. Parenting programmes that encourage investment in young children are a promising tool for improving early development outcomes and long-term opportunities in low-income and middle-income regions, such as rural China.MethodsWe conducted a systematic review and a meta-analysis to investigate the prevalence of early developmental delays and stimulating parenting practices as well as the effect of parental training programmes on child development outcomes in rural China. We obtained data in English from EconPapers, PubMed, PsycARTICLES, Cochrane Library, Web of Science and Scopus (Elsevier) and in Chinese from China National Knowledge Infrastructure, Wanfang Data and VIP Information. We conducted frequentist meta-analyses of aggregate data and estimated random-effects meta-regressions. Certainty of evidence was rated according to the Grading of Recommendations Assessment, Development and Evaluation approach.ResultsWe identified 19 observational studies on the prevalence of developmental delays and stimulating parenting practices for children under 5 years of age (n=19 762) and ten studies on the impact of parental training programmes on early child development (n=13 766). Children’s risk of cognitive, language and social-emotional delays in the rural study sites (covering 14 provinces mostly in Central and Western China) was 45%, 46%, and 36%, respectively. Parental training programmes had a positive impact on child cognition, language and social-emotional development.ConclusionThere is evidence to suggest that early developmental delay and the absence of stimulating parenting practices (ie, reading, storytelling and singing with children) may be prevalent across rural, low-income and middle-income regions in Central and Western China. Results support the effectiveness of parental training programmes to improve early development by encouraging parental engagement.Trial registration numberThis study was registered with PROSPERO (CRD42020218852).
Inadequate care during early childhood can lead to long-term deficits in skill development. Parenting programs are promising tools for improving parenting practices and opportunities for healthy development. We implemented a non-masked cluster-randomized controlled trial in rural China in order to assess the effectiveness of an integrated home-visitation program that includes both psychosocial stimulation and health promotion at fostering development and health outcomes of infants and toddlers in rural China. All 6-18 month-old children of two rural townships and their main caregiver were enrolled. Villages were stratified by township and randomly assigned to intervention or control. Specifically, in September 2015 we assigned 43 clusters to treatment (21 villages, 222 caregiver-child dyads) or control (22 villages, 227 caregiver-child dyads). In the intervention group, community health workers delivered education and training on how to provide young children with psychosocial stimulation and health care (henceforth psychosocial stimulation and health promotion) during biweekly home visits over the period of one year. The control group received no home visits. Primary outcomes include measures of child development (i.e. the Bayley Scales of Infant and Toddler Development, third edition-or Bayley-III) and health (i.e. measures of morbidity, nutrition, and growth). Secondary outcomes are measures of parenting practices. Intention-to-treat (ITT) effects show that the intervention led to an improvement of 0•24 standard deviations (SD) [95% CI 0•04 SD-0•44 SD] in cognitive development and to a reduction of 8•1 [95% CI 3•8-12•4] percentage points in the risk of diarrheal illness. In addition, we find positive effects on parenting practices mirroring these results. We conclude that an integrated psychosocial stimulation and health promotion program improves development and health outcomes of infants and toddlers (6-30 month-old children) in rural China. Because of low incremental costs of adding program components (that is, adding health promotion to psychosocial stimulation programs), integrated programs may be cost-effective.
We propose a model in which parents have a subjective belief about the impact of their investment on the early skill formation of their children. This subjective belief is determined in part by locus of control (LOC), i.e., the extent to which individuals believe that their actions can influence future outcomes. Using a unique British cohort survey, we show that maternal LOC measured during the 1st-trimester strongly predicts early and late child cognitive and noncognitive outcomes. Further, we utilize the variation in maternal LOC to improve the specification typically used in the estimation of parental investment effects on child development.
