N1 - Funding Information:
AN received financial support for predoctoral training from a National Science Foundation Innovation Corps Sites Program Award from the Missouri University of Science and Technology and a Spencer T and Ann W Olin Fellowship from the Washington University in St Louis. The authors would like to thank Tiffany Dill, Kelly Monroy, and members of the HMOTA for their assistance in identifying OTs for inclusion in the mobile directory. The authors would also like to thank the older adults and OTs who participated in the study for their time to provide valuable feedback.

N2 - Background: Home modifications provided by occupational therapists (OTs) are effective in improving daily activity performance and reducing fall risk among community-dwelling older adults. However, the prevalence of home modification is low. One reason is the lack of a centralized database of OTs who provide home modifications. Objective: This study aimed to develop and test the usability of a mobile app directory of OTs who provide home modifications in the United States. Methods: In phase 1, a prototype was developed by identifying OTs who provide home modifications through keyword Web searches. Referral information was confirmed by phone or email. In phase 2, community-dwelling older adults aged older than 65 years and OTs currently working in the United States were purposefully recruited to participate in a single usability test of the mobile app, Home Modifications for Aging and Disability Directory of Referrals (Home Maddirs). Participants completed the System Usability Scale (SUS) and semistructured interview questions. Interview data were coded, and themes were derived using a grounded theory approach. Results: In phase 1, referral information for 101 OTs across 49 states was confirmed. In phase 2, 6 OTs (mean clinical experience 4.3 years, SD 1.6 years) and 6 older adults (mean age 72.8 years, SD 5.0 years) participated. The mean SUS score for OTs was 91.7 (SD 8.0; out of 100), indicating good usability. The mean SUS score for older adults was 71.7 (SD 27.1), indicating considerable variability in usability. In addition, the SUS scores indicated that the app is acceptable to OTs and may be acceptable to some older adults. For OTs, self-reported barriers to acceptability and usability included the need for more information on the scope of referral services. For older adults, barriers included high cognitive load, lack of operational skills, and the need to accommodate sensory changes. For both groups, facilitators of acceptability and usability included perceived usefulness, social support, and multiple options to access information. Conclusions: Home Maddirs demonstrates good preliminary acceptability and usability to OTs. Older adults' perceptions regarding acceptability and usability varied considerably, partly based on prior experience using mobile apps. Results will be used to make improvements to this promising new tool for increasing older adults' access to home modifications.
