Objective: The research-oriented objective of this study was to document the effectiveness of online support for hearing aid (HA) users compared with traditional support. Design: This study is a randomised controlled trial with parallel group design. The research-oriented objectives were evaluated using the Hearing Handicap Inventory for the Elderly (HHIE) and the Communication Strategies Scale (CSS) at baseline and immediately postintervention. Study sample: Selected clients at five different clinics were randomised to an intervention group (n = 78) that took part in online hearing support and a control group (n = 58) that received standard care. Results: The analyses (intention-to-treat) showed statistically significant improvements in the HHIE-total and Emotional subscale scores for the intervention group compared with the control group. The intervention group also showed significantly greater improvement in the CSS-total and Verbal and Nonverbal subscale scores. A subgroup analysis was performed including two groups: HA use and HA use >1 year. A statistically significant improvement was found for the HA users >1 year compared with HA use Conclusions: It is effective to clinically include online hearing support for HA users when addressing self-perceived hearing difficulties and to sharpen communication strategy skills.
