• The SOUND programme is built on a sequential causal chain integrating Family Social Support theory, the Technology Acceptance Model, and Self-Determination Theory. — Family-supported hearing aid use behaviour intervention to improve outcomes in older adults at high risk for dementia (SOUND): study protocol for a randomised controlled trial
• Self-Determination Theory distinguishes controlled motivation, driven by external pressure, from autonomous motivation, driven by genuine personal valuation. — Family-supported hearing aid use behaviour intervention to improve outcomes in older adults at high risk for dementia (SOUND): study protocol for a randomised controlled trial
• The three TAM constructs targeted in the SOUND intervention are perceived ease of use, perceived compatibility, and perceived observability. — Family-supported hearing aid use behaviour intervention to improve outcomes in older adults at high risk for dementia (SOUND): study protocol for a randomised controlled trial
• TAM-related constructs are not measured with dedicated validated instruments, so the trial cannot formally test the underlying theoretical mechanism. — Family-supported hearing aid use behaviour intervention to improve outcomes in older adults at high risk for dementia (SOUND): study protocol for a randomised controlled trial
• Family support mediated through TAM perceptions is hypothesised to promote identification regulation and integration regulation, converting external prompts into durable internal motivation. — Family-supported hearing aid use behaviour intervention to improve outcomes in older adults at high risk for dementia (SOUND): study protocol for a randomised controlled trial
