Identity resilience is conceptualized in Identity Process Theory as a relatively stable self-schema, akin to a trait. Identity resilience is said to be high when individuals perceive their identity to be characterized by a high overall combined rating of their self-efficacy, self-esteem, continuity and distinctiveness. People reporting higher identity resilience respond more favorably to, and cope more effectively with, events and situations that question or threaten their identity. The Identity Resilience Index (IRI) is a 16-item self-report measure of identity resilience. Confirmatory factor analysis was performed on data from 465 participants in two studies in the United Kingdom who completed the IRI and the Positive Affect Scale. Results revealed a second-order factor model in which every item loaded onto one of four first-order identity dimensions (self-esteem, self-efficacy, continuity and distinctiveness) and indicated these four first-order dimensions loaded onto a higher-order identity factor (identity resilience). Overall, we found no statistically significant differences on the IRI by population (general vs. gay men). The IRI correlated positively with the Positive Affect Scale, suggesting good concurrent validity.

身份弹性指数：两个英国样本的开发和验证

身份复原力在身份过程理论中被概念化为一种相对稳定的自我图式，类似于特征。当个人认为他们的身份以他们的自我效能、自尊、连续性和独特性的高综合评价为特征时，身份复原力就被认为是高的。报告具有较高身份复原力的人对质疑或威胁其身份的事件和情况反应更积极，也更有效地应对。身份复原力指数 (IRI) 是一项包含 16 项自我报告的身份复原力指标。对英国两项研究中完成 IRI 和积极影响量表的 465 名参与者的数据进行了验证性因素分析。结果揭示了一个二阶因子模型，其中每个项目加载到四个一阶身份维度（自尊、自我效能、连续性和独特性）中的一个，并表明这四个一阶维度加载到更高阶身份因素（身份弹性）。总体而言，我们发现 IRI 按人群（一般与男同性恋者）没有统计学上的显着差异。IRI 与积极影响量表呈正相关，表明良好的同时效度。
