Abstract
The association between patients' dietary nonadherence and spouses' involvement in patients' diabetes diet was examined, with spouses' anxiety about nonadherence considered as a mediator of this association. Daily diary data from 128 older adult patients with type 2 diabetes and their spouses were analyzed using multilevel models. Results revealed that on days when patients reported less adherence to their diabetes diet than usual, spouses reported greater anxiety about patients' diabetes management, which, in turn, was related to greater spousal persuasion and pressure the same day. The association between patients' nonadherence and diet‐related support on the same day was not mediated, however, through spouses' anxiety. The findings contribute to an understanding of spouses' responses to patients' nonadherence to their diabetes regimen.
