METHODS: Phase I involves three steps: (a) translating the intervention manual into Malay, (b) systematically adapting its content for cultural relevance, and (c) piloting the intervention. Phase II is a 4-month randomized controlled feasibility trial involving chronic tinnitus patients (n = 20), stratified by severity and randomly assigned to either (a) the adapted intervention delivered by a trained provider or (b) standard care. Feasibility outcomes include a 10% recruitment rate among eligible patients, a 65% eligibility rate within the target population, and 80% retention. Primary outcomes assess tinnitus severity via the Tinnitus Functional Index, while secondary outcomes measure psychological distress using the Depression Anxiety Stress Scale-42. Assessments occur at baseline, post-intervention (1 month), and at a 3-month follow-up. At follow-up, semi-structured interviews guided by the Theoretical Framework of Acceptability will explore participants' perceptions of the intervention.

DISCUSSION: This feasibility trial evaluates the practicality and acceptability of a culturally adapted, audiologist-delivered psychological intervention for chronic tinnitus patients in Malaysia. Unlike direct translations, it incorporates systematic cultural adaptation to ensure relevance for the target population. Findings will inform the viability of a future large-scale trial and the potential for expanding psychologically informed tinnitus care in audiology settings.
