Objective: To (i) assess the delivery, accessibility, usability, acceptability, and adherence, and (ii) identify suitable outcome measures, for a mobile-enhanced multimedia educational programme (m2Hear) in firsttime hearing aid users. Design: A prospective, single-centre feasibility study. Study sample: First-time hearing aid users (n ¼ 59), recruited at their initial hearing assessment. Evaluations were made at 1-week and at 10-12 weeks post-hearing aid fitting. Results: m2Hear was most commonly accessed via tablets (42.3%). Usability was high for the System Usability Scale (88.5%), and the uMARS, particularly for the Information (M ¼ 4.7), Functionality (M ¼ 4.5) and Aesthetics (M ¼ 4.2) subscales (maximum score ¼ 5). Participant feedback was positive, with a high percent agreeing that m2Hear aided understanding of hearing aids (98%), held their interest (86%), improved confidence to use hearing aids and communicate (84%), and provided additional information to audiologist's advice (82%). Learnings about practical hearing aid handling/maintenance skills and how to communicate with others were reportedly used equally in participant's everyday lives. m2Hear was convenient to use, clear, concise and comprehensive. Outcome measures of social participation resulted in large effect sizes (Cohen's d > 1.6). Conclusions: A theoretically-driven, personalised and co-designed educational m-health intervention is feasible and beneficial for use in the self-management of hearing loss and hearing aids.
