Optimising the validity and completion of adherence diaries: a multiple case study and randomised crossover trial.

ABSTRACT:

Background

Diaries are the most commonly used adherence measurement method in home-based rehabilitation trials, yet their completion and validity varies widely between trials. We aimed to: (1) generate theory to explain this variation, (2) create an optimised diary and (3) evaluate the optimised diary's validity.

Methods

Stage 1.

Development

using a multiple case study approach, we collected trialist interviews (n = 7), trial publications (n = 16) and diaries (n = 7) from seven purposively sampled UK rehabilitation trials. We explored return rates, diary designs and trialists' ideas as to what affected diary completion and validity. Using explanatory case study analysis, we developed a diary optimisation model. Stage 2.

Evaluation

we compared a diary optimised
