Increasing self-esteem among left-behind children in China: a cross-temporal meta-analysis from 2006 to 2020

Self-esteem serves as a fundamental indicator for assessing the mental health of left-behind children in China. Previous studies have placed more emphasis on investigating its current situation, while overlooking its dynamic changes with social development.

This research project used the approach of cross-temporal meta-analysis to analyze 72 papers that used the Rosenberg Self-esteem Scale, ranging from 2006 to 2020(date of data collection) and covering 29,835 left-behind children, to delve into the diachronic changes and influencing factors of self-esteem of left-behind children over the years.

The outcomes demonstrated that: (1) The self-esteem scores of Chinese left-behind children increased from 30.74 in 2006 to 32.7 in 2020. (2) The level of self-esteem among left-behind children was significantly correlated with social indicators (economic conditions and educational level) for the actual year, 3 years prior, or 5 years prior to the self-esteem data collection.

The level of self-esteem of left-behind children has been rising between 2006 and 2020. In addition, it is noteworthy that social development had a significant influence on predicting changes in the self-esteem of left-behind children.
