"Background: The aim of this study was to explore the psychometric properties of the Motiva.Diaf-DM2 questionnaire, which assesses adherence to a healthy diet and physical activity in patients with Type 2 Diabetes (T2D). Method: Participants were 206 patients who attended primary care services, with a mean age of 69.63 years (SD = 11.05), with 39.3% of the participants being women. To assess the test-retest reliability of the measure, a random subsample (n = 40) of patients who had another appointment scheduled was selected to fill in the questionnaire once again two weeks after the initial administration. Results: The reliability of the scores was found to be appropriate both in terms of internal consistency (α first factor = .756; α second factor = .821) and temporal stability (r first factor = .604; r second factor = .638). The structure of the test is two-dimensional. The scores for the second dimension (adherence to physical activity) are in agreement with the scores for basic psychological needs (r physical activity = .281), resilience (r = .216), and glycated haemoglobin (r = -.182). Conclusions: The Motiva.Diaf-DM2 test was shown to have the appropriate reliability and validity to assess adherence to a healthy diet and physical activity in patients diagnosed with T2D."
