Parenting centers and caregiver mental health: Evidence from a large-scale randomized controlled trial in China

Effectiveness of a government-led, multiarm intervention on early childhood development and caregiver mental health: a study protocol for a factorial cluster-randomised trial in rural China

INTRODUCTION

The high incidences of both the developmental delay among young children and the mental health problems of their caregivers are major threats to public health in low-income and middle-income countries. Parental training interventions during early childhood have been shown to benefit early development, yet evidence on strategies to promote caregiver mental health remains limited. In addition, evidence on the optimal design of scalable interventions that integrate early child development and maternal mental health components is scarce.

METHODS AND ANALYSIS

We design a single-blind, factorial, cluster-randomised controlled, superiority trial that will be delivered and supervised by local agents of the All China Women's Federation (ACWF), the nationwide, government-sponsored social protection organisation that aims to safeguard the rights and interests of women and children. We randomise 125 villages in rural China into four arms: (1) a parenting stimulation arm; (2) a caregiver mental health arm; (3) a combined parenting stimulation and caregiver mental health arm and (4) a pure control arm. Caregivers and their children (aged 6-24 months at the time of baseline data collection) are selected and invited to participate in the 12-month-long study. The parenting stimulation intervention consists of weekly, one-on-one training sessions that follow a loose adaptation of the Reach Up and Learn curriculum. The caregiver mental health intervention is comprised of fortnightly group activities based on an adaptation of the Thinking Healthy curriculum from the WHO. Primary outcomes include measures of child development and caregiver mental health. Secondary outcomes include a comprehensive set of physical, psychological and behavioural outcomes. This protocol describes the design and evaluation plan for this programme.

ETHICS AND DISSEMINATION

This study received approval from the Institutional Review Board of Stanford University (IRB Protocol #63680) and the Institutional Review Board of the Southwestern University of Finance and Economics in Chengdu, Sichuan, China. Informed oral consent will be obtained from all caregivers for their own and their child's participation in the study. The full protocol will be publicly available in an open-access format. The study findings will be published in economics, medical and public health journals, as well as Chinese or English policy briefs.

Impact of an Early Childhood Development Intervention on the Mental Health of Female Caregivers: Evidence from a Randomized Controlled Trial

Investing in early childhood development is an effective way to enhance human capital accumulation. Caregivers' mental health is one of the most important factors influencing children's development. Previous studies have found that mental health issues in caregivers are widespread all over the world, especially in low- and middle-income countries. In this study, we explored the effects of the "Integrated Program for Early Childhood Development" on the mental health of female caregivers in Southwest China through a randomized intervention trial, with infants aged 5-25 months and their caregivers as the target subjects. The heterogeneity of the effects of different characteristics of the caregivers and the mechanism of the intervention effect were also analyzed. Primary caregivers were provided comprehensive early development interventions for the children in the treatment group via bi-weekly home visiting activities and monthly family group activities. The results showed that the prevalence of depression, anxiety, and stress symptoms among female caregivers in this rural area were 32%, 42%, and 30%, respectively. Whether the child was breastfed, parent's age, parent's education level, primary caregiver type, the ratio of the number of months the mother was at home full time to the child's age, the grandmother's rearing ability, and the family asset index were the factors influencing the mental health of female caregivers. The intervention significantly increased the proportion of depressive symptoms in 28% of the grandmothers. It significantly reduced the anxiety symptoms of daughters-in-law not from the local town, while the social interactions of both local and non-local daughters-in-law were significantly improved.
