Methods
A parallel randomized control trial was designed to assess the
effectiveness of a 4-week intervention based on the integrated
theoretical model in adults with T2D. The factors and underlying beliefs
identified for intervention focus were based on an initial, formative
qualitative study among 30 T2D participants. Ethical approval was
obtained from the Ethics Committee of “Blinded for Review”. Given
there are no national dietary or educational guidelines for diabetes in
Iran, target behaviours were adapted from international guidelines such
as the American Diabetes Associations (ADA,
2017), Diabetes Australia (Diabetes
Australia, 2015), and the Joslin Diabetes Center
(Joslin Diabetes Center, 2019). The study
was registered with the Iranian Registry of Clinical Trials
(IRCT2013040912961N1).
