How do we measure adherence?
Adherence was measured using a continuous scale rather than as a dichotomous division into adherent/nonadherent categories. Participants were asked to rate the frequency with which they engaged in each of the adherence‐related behaviours on a five‐point scale, where 5 = never, 4 = rarely, 3 = sometimes, 2 = often and 1 = always.
