Objective To explore the antecedents of adolescent psychological capital and its influencing mechanism.Methods A total of 312 middle school students aged 11-17 years were measured with the Chinese version of emotional stability scale(ESS),inventory of parent and peer attachment(IPPA)sub-questionnaire of mother-child attachment,the Chinese version of positive psycap questionnaire(PPQ),and family socioeconomic status scale.The relevant data were statistically analyzed.Results Maternal emotional stability had a significantly positive predictive effect on adolescent psychological capital(P<0.001).Mother-child attachment partially mediated the relationship between the emotional stability of mothers and the psychological capital of adolescents.The family socioeconomic status played a regulatory role between the emotional stability of mothers and the psychological capital of adolescents.When the family socioeconomic status was high,the emotional stability of mothers had a strong role in promoting the psychological capital of adolescents.Conclusion The emotional stability of mothers can not only directly affect the psychological capital of adolescents,but also indirectly affect the psychological capital of adolescents through mother-child attachment.Family socioeconomic status regulates the direct effect of emotional stability of mothers on the psychological capital of adolescents.

目的 探讨青少年心理资本的前因变量及其影响机制。方法 采用情绪稳定性量表、父母与同伴依恋问卷中的母子依恋分问卷、积极心理资本问卷及家庭社会经济地位量表对312名11～17岁中学生进行测量，对相关数据进行统计学分析。结果 母亲情绪稳定性对青少年心理资本有显著的正向预测作用（P<0.001）。母子依恋在母亲情绪稳定性与青少年心理资本之间起部分中介作用。家庭社会经济地位在母亲情绪稳定性与青少年心理资本之间起调节作用；当家庭社会经济地位高时，母亲情绪稳定性对青少年心理资本的促进作用较强。结论 母亲情绪稳定性既可以直接作用于青少年心理资本，也可以通过母子依恋间接作用于青少年心理资本；家庭社会经济地位调节了母亲情绪稳定性对青少年心理资本的直接效应。
