In this article, we report the results of 3 studies evaluating the psychometric properties of scores generated using the Erikson Psychosocial Stage Inventory (EPSI; Rosenthal, Gurney, & Moore, 1981) with emerging adults. In Study 1, a hybrid bifactor solution, consisting of an overall identity factor as well as of "method effects" factors for identity synthesis and identity confusion, provided a better fit to the data than did either one or two-factor solutions. This bifactor solution was largely invariant across gender and across Whites, Blacks, and Hispanics. In Study 2, the overall identity, identity synthesis, and identity confusion scores were shown to possess convergent validity with another Eriksonian measure and with measures of identity status. In Study 3, the EPSI subscale scores were shown to possess construct validity vis-a-vis self-esteem, purpose in life, internal locus of control, ego strength, anxiety, and depression. We discuss implications for the measurement of identity.
在本文中，我们报告了3项研究的结果，这些研究评估了使用埃里克森社会心理发展阶段量表（EPSI；罗森塔尔、格尼和摩尔，1981年）对新兴成年人所产生分数的心理测量特性。在研究1中，一种混合双因素解决方案，由一个整体同一性因素以及同一性整合和同一性混乱的“方法效应”因素组成，比单因素或双因素解决方案更能拟合数据。这种双因素解决方案在性别以及白人、黑人和西班牙裔群体中基本保持不变。在研究2中，整体同一性、同一性整合和同一性混乱分数与另一项埃里克森测量方法以及同一性状态测量方法具有收敛效度。在研究3中，EPSI分量表分数相对于自尊、生活目的、内控点、自我力量、焦虑和抑郁具有结构效度。我们讨论了这些结果对同一性测量的意义。
