Implication

Randomized trial observes higher response rates with theory-informed cover letters in diabetic foot ulcer participants, suggesting modest retention gains.

Key Points

Higher response rates occurred among participants receiving cover letters designed using behaviour-change theory across all postal survey timepoints.
Response rates reached 70.3% with enhanced letters compared to 55.6% for standard mailings of the mailed questionnaire during annual follow-up.
Randomised controlled trial embedded within a diabetic foot ulcer study evaluated two cover letters, though limited recruitment constrained precision.
