The objective of this study was to investigate and analyze the status and influential factors of gender equality awareness, self-esteem, and subjective well-being in school-age boys and girls. The results can help schools and teachers provide more effective gender equality and mental health education. In the study, 284 valid questionnaires were collected from a total of 323 school-age boys and girls in the Hunan Province, China. The questionnaire covered gender equality awareness, self-esteem, and subjective well-being, with the influencing factors analyzed (...) through multiple linear regression. There was a significant correlation among children’s gender equality awareness in all areas examined, with both boys and girls having the lowest awareness of gender equality in occupational fields. The children’s self-esteem and subjective well-being were significantly correlated as well. Gender equality awareness, self-esteem, and subjective well-being among boys and girls reflected different influential factors. Androgynous traits were conducive to the development of gender equality awareness and self-esteem among the children. Therefore, schools and teachers need to provide gender equality and mental health education according to the specific psychological characteristics of each boy and girl. (shrink)
