Thirty-nine first time hearing aid users with mild to moderate hearing losses were randomly assigned to a pre-fitting intervention group (N=19) or a control group (N=20). The pre-fitting intervention consisted of three weekly visits, where the user adjusted the amplification of an experimental hearing aid to preferred settings, and wore the aid between the visits. After the pre-fitting intervention phase, both groups received conventional hearing aid fitting. Standardized questionnaires (IOI-HA, HHIE, ECHO, SADL, HADS) were administered before and after pre-fitting intervention, after conventional hearing aid fitting, and at one-year follow-up. Hearing aid success was evaluated by an independent audiologist at the one- year follow-up appointment. The pre-fitting intervention phase showed positive effects for the intervention group but not for the control group on activity limitation and participation restriction, and expectations. However, the intervention in its current version had no lasting effects beyond the control group after conventional hearing aid fitting or after a year. Furthermore, both groups showed mostly successful hearing aid fittings, improved psychosocial well-being, quality of life, and reduced participation restriction.
