Validation of the PTPI Scale for Technology Products Among Users with Disabilities.

The Perceptions of Technology Product Inclusivity (PTPI) Scale was previously validated to assess perceptions of inclusivity with a wide variety of technology products and users. This study explores the use of the PTPI with a specific population, technology product users with disabilities, to determine if the scale appropriately assesses their perceptions of technology product inclusivity. The PTPI was administered via Qualtrics to 201 participants who self-reported having a disability. The technology products evaluated in this study covered 23 categories and contained a variety of products within those categories. A confirmatory factor analysis (CFA) was conducted to assess model fit. The CFA results indicated that the PTPI has acceptable model fit for all five subscales: Personal Connection, Product Challenges, Confidence in Usage, Meets Expectations, and Company Empathy. Thus, the PTPI is appropriate to use with technology product users with disabilities. Future research can be done to show how the validated 5-factor PTPI varies across technology products targeted to disabled users to identify design characteristics contributing to perceptions of inclusivity.
