This study aimed to develop a 12-item version of the Erikson Psychosocial Stage Inventory (the 5th stage) (EPSI (5th)) and examine its reliability and validity. University students (N = 545) participated in this study. Confirmatory factor analyses revealed that a two-factor model provided a better fit than alternative one-factor models. An analysis of Cronbach's α coefficients and the test-retest method showed acceptable scale reliability. In accordance with our hypotheses, correlation analyses revealed that the EPSI (5th) subscale scores (i.e., synthesis and confusion) were significantly related to measures of self-esteem, life satisfaction with life, and identity confusion. Implications and suggestions for future research are discussed.
本研究旨在开发一个12项版的埃里克森社会心理发展阶段量表（第5阶段）（EPSI(5)），并检验其信效度。545名大学生参与了本研究。验证性因素分析表明，两因素模型比其他单因素模型拟合度更好。对克朗巴哈α系数的分析以及重测法显示该量表具有可接受的信度。与我们的假设一致，相关性分析表明EPSI(5)分量表得分（即整合和混乱）与自尊、生活满意度和身份认同混乱的测量指标显著相关。文中还讨论了对未来研究的启示和建议。
