PURPOSE/OBJECTIVE This work provides comprehensive analyses targeting the factor structure and dimensionality of the Disability Identity Development Scale (DIDS). In Forber-Pratt et al., 2020, disability was defined broadly to include individuals with visible or hidden disabilities across many disability groups (i.e., physical, intellectual, learning, or chronic illness). RESEARCH METHOD/DESIGN Retained items from previous exploratory factor analysis were administered to a sample of adults with disabilities (n = 1,126) ranging in age from 18-78 years. Confirmatory factor analytics (CFA) including traditional CFA, and bifactor confirmatory analyses were used to examine the dimensionality and structure of the DIDS. RESULTS Traditional CFA provided lack of evidence in support of the oblique four-factor structure previously reported. Bifactor confirmatory analysis revealed items on the DIDS are consistent with unidimensional, and to a lesser degree multidimensional solutions (i.e., items lacked a level of content diversity to substantiate a complex, reliable multifactor structure). DISCUSSION/CONCLUSION Analytic results on the DIDS revealed reasonable psychometric properties as a measure of disability identity. Our results support using a sum or total score of disability identity. Results of this work are an important contribution to a growing body of literature supporting, and investigating, disability identity development. Furthermore, the DIDS measure with its resulting composite score of disability identity has the potential to inform clinicians in the field of rehabilitation psychology as well as informing future targeted interventions.

残疾身份发展量表的心理测量特性：确认因素和双因素分析。

目的/目标 这项工作提供了针对残疾身份发展量表 (DIDS) 的因素结构和维度的综合分析。Forber-Pratt 等人在 2020 年对残疾进行了广泛定义，包括许多残疾群体（即身体、智力、学习或慢性病）中具有明显或隐藏残疾的个人。研究方法/设计 对年龄在 18-78 岁之间的残疾成人样本 (n = 1,126) 进行先前探索性因素分析的保留项目。包括传统 CFA 在内的验证性因素分析 (CFA) 和双因素验证性分析用于检查 DIDS 的维度和结构。结果 传统 CFA 缺乏证据支持先前报道的倾斜四因素结构。双因素验证分析显示 DIDS 上的项目与一维一致，并且在较小程度上与多维解决方案一致（即，项目缺乏一定程度的内容多样性来证实复杂、可靠的多因素结构）。讨论/结论 DIDS 的分析结果揭示了合理的心理测量特性作为残疾身份的衡量标准。我们的结果支持使用残疾身份的总分或总分。这项工作的结果对越来越多的支持和调查残疾认同发展的文献做出了重要贡献。此外，DIDS 测量及其产生的残疾身份综合评分有可能为康复心理学领域的临床医生提供信息，并为未来的针对性干预提供信息。
