| During the novel coronavirus pandemic,volunteers chose to stay on the front lines despite the risk of possible infection.The ability to stand up in the face of danger is known as prosocial risk-taking.Junior high school students are at a critical stage of prosocial risk-taking.How to guide the development of prosocial risk-taking behavior and promote the development of positive qualities of junior high school students is one of the key issues in basic education.Previous studies have found that both family factors and personal cognition are important factors affecting prosocial risk-taking behavior.Therefore,based on ecosystem theory,human-environment interaction theory and social cognition theory,this study explores the relationship between parenting style,just world belief,gender and prosocial risk-taking behavior of junior high school students.The prosocial Risk-taking Behavior Scale,Parenting style Scale and Just World Belief Scale were used to investigate junior middle school students in a middle school in Northwest China.The study was carried out in two steps.In the first study,770 junior high school students were surveyed.The influence of parenting style and belief in a just world on prosocial risk-taking behavior and its mechanism are discussed horizontally.In the second study,337 junior high school students were surveyed twice,6 months apart.The longitudinal study verifies the stability of the mechanism that parental rearing style influences prosocial risk-taking behavior of junior middle school students through belief in a just world.The main results of this study are as follows:(1)There were significant differences in middle school students’ pro-social risk-taking behaviors by gender,grade level,whether they were only children,and family location,specifically,more boys than girls,more seventh graders than eighth graders,more only children than non-only children,and more middle school students living in urban areas than those living in non-urban areas.(2)Parental emotional warmth was positively correlated with just world belief and prosocial risk-taking behavior,while parental rejection and overprotection were negatively correlated with just world belief and prosocial risk-taking behavior.(3)In both cross-sectional and longitudinal studies,just world belief plays a mediating role between parental emotional warmth and prosocial risk-taking behavior of junior high school students.In the cross-sectional study,just world belief plays a mediating role in parental rejection and prosocial risk-taking behavior of junior high school students,while in the longitudinal study,the mediating effect is not significant.Just world belief has no mediating effect between parents’ overprotection and junior high school students’ prosocial risk-taking behavior.Through cross-validation of transverse and longitudinal studies,Parents’ emotional warmth can not only directly affect the prosocial risk-taking behavior of junior middle school students,but also influence their prosocial risk-taking behavior through belief in a just world.This mechanism is stable.Just world belief masked the negative predictive effect of parental rejection on prosocial risk-taking behavior of junior middle school students,but this mechanism did not predict prosocial risk-taking behavior 6 months later. |
