If older adults with moderate hearing loss wear hearing aids for three months, they often feel like their daily life gets better and listening to people becomes less tiring.

Appropriate Language Strength
association
Can only show association/correlation
Assessment Explanation
The claim uses 'associated with,' which correctly reflects a correlational relationship observed in observational or interventional studies. It does not claim causation (e.g., 'hearing aids cause improvement'), which is appropriate given that even randomized trials may have confounders. The outcome measures (HHIE, SF36, VAS) are validated tools, and the population and duration are specific enough to be testable. No overstatement is present.

Cognition and benefit obtained with hearing aids: a study in elderly people.
The study gave hearing aids to older adults with hearing loss for three months and found they felt better, had less trouble listening, and enjoyed life more—exactly what the claim says.
