目的探讨中学生坚毅、自我同一性与自尊的关系,为中学生坚毅的研究提供依据。方法采用分层整群抽样法于2019年3月选取福建某市2所普通中学1 476名中学生作为研究对象,采用坚毅量表(Grit-12)、自我同一性量表(SIS)、自尊量表(SES)进行问卷调查。结果相关分析表明,中学生坚毅的坚持努力、兴趣一致与自我同一性和自尊均呈正相关(r值分别为0.40,0.31; 0.46,0.18,P值均<0.01),自我同一性与自尊呈正相关(r=0.67,P<0.01)。中介作用检验结果表明,自我同一性在坚毅的坚持努力与自尊之间起部分中介作用,中介效应占总效应的50.38%;自我同一性在坚毅的兴趣一致与自尊之间起完全中介作用。结论中学生自我同一性在坚毅的坚持努力对自尊的关系中具有部分中介效应,在坚毅的兴趣一致对自尊的关系中具有完全中介效应。
