WhatsApp AI Support vs Paper Support for First-Time Hearing Aid Users

The purpose of this study is to advance hearing care in low- and middle-income countries (LMICs) through the rigorous evaluation and optimization of innovative interventions and technologies. This study encompasses the following key aim: This study aims to evaluate the effectiveness of a WhatsApp-delivered AI-enabled support and acclimatization programme for adults receiving preset hearing aids in low-resource community settings. The AI-enabled programme combines two complementary components delivered through the same WhatsApp channel: (i) a structured push programme of 16 voice notes and images delivered over four weeks, and (ii) an on-demand artificial-intelligence (AI) conversational support agent available throughout the four-week intervention period. The primary objective is to determine whether this WhatsApp-delivered AI-enabled programme results in superior hearing aid self-efficacy compared to receiving the equivalent core information in a paper-based pamphlet at the time of fitting. By comparing hearing aid self-efficacy, hearing aid outcomes, and user engagement between the intervention (WhatsApp AI-enabled) and control (paper-based) groups, this study seeks to establish whether AI-enabled digital delivery provides superior support and leads to better self-efficacy for first-time hearing aid users compared to traditional paper-based methods.
