The Impact of Peer Relationship on Prosocial Risk-Taking Behavior among High School Students: A Moderated Chain Mediation Model

为探讨同伴关系对高中生亲社会冒险行为的影响及作用机制，本研究选取儿童青少年同伴关系量表、自尊量表、公正世界信念量表、父母自主支持量表和青少年亲社会冒险行为量表，通过整群抽样的方式对1102名高中生进行施测。结果表明：(1) 同伴关系显著负向预测高中生亲社会冒险行为；(2) 同伴关系可通过自尊与公正世界信念的单独中介作用以及“自尊→公正世界信念”的链式中介作用影响高中生亲社会冒险行为；(3) 父母自主支持调节“同伴关系→自尊→公正世界信念→亲社会冒险行为”链式中介模型。研究提供了理论基础和实证支持以便引导和干预高中生的亲社会冒险行为。To explore the impact and mechanism of peer relationship on high school students’ prosocial risk-taking behavior, this study selected the children and adolescent peer relationship scale, self-esteem scale, belief in a just world scale, parental autonomy support scale, and adolescent prosocial risk-taking behavior scale. A total of 1102 high school students were tested through cluster sampling. The results indicate that: (1) Peer relationship significantly negatively predicts high school students’ prosocial risk-taking behavior; (2) Peer relationships can influence high school students’ prosocial risk-taking behavior through the individual mediating effect of self-esteem and belief in a just world, as well as the chain mediating effect of “self-esteem→belief in a just world”; (3) The chain mediation model of parental self-directed support regulating “peer relationships→self-esteem→belief in a just world→prosocial risk-taking behavior”. The study provides a theoretical foundation and empirical support to guide and intervene in high school students’ prosocial risk-taking behavior.
