Abstract
Forber-Pratt and colleagues' Disability Identity Development Scale (DIDS) is the only disability identity measure that meets all the criteria for rigorous scale development. Little is known however about item fit for the DIDS.
Purpose/objective: (a) To investigate the construct validity of the DIDS scores at the item and factor level using item response theory (IRT) and confirmatory factor analysis (CFA); (b) to investigate convergent validity of the DIDS scores with related constructs; and (c) to determine the reliability of each DIDS factor.
Research method/design: A convenience sample of 210 undergraduate college students with disabilities enrolled in a west coast 4-year public university participated in this study. Measures included the DIDS, the University Belongingness Questionnaire, and the College Self-Efficacy Inventory. Data were analyzed using the Rasch IRT framework, CFA, Omega reliability, and correlational analyses.
Results: IRT and CFA results revealed the data fit a 36-item, four-factor DIDS structure. Three items in the factor measuring adoption of disability community values items were easier, and four items in the factor measuring contribution to the disability community were difficult as compared with other DIDS items. Omega reliability analyses showed strong reliability for each DIDS factor. Correlation analyses found convergent and discriminant validity evidence for the DIDS with correlations with the University Belongingness Questionnaire and College Self-Efficacy Inventory in the hypothesized direction and magnitude.
Conclusion/implications: Findings provide evidence for Forber-Pratt and colleagues' theoretically and empirically derived DIDS, advancing the research, measurement, and practical application of disability identity development. Results are aligned with Forber-Pratt's psychosocial model of disability identity theoretical framework. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
