Self-determination theory and motivational interviewing interventions for type 2 diabetes prevention and treatment: A systematic review:

Treatment of those with obesity, prediabetes, and type 2 diabetes often yields initial health improvements, but gains erode over time. A systematic search of self-determination theory and motivational interviewing papers for the above populations was conducted, yielding 54 publications and 42 independent samples. Interventions to treat overweight and obesity (n = 15), prediabetes (n = 4), and type 2 diabetes (n = 23) are summarized and evaluated using the Quality Rating Scale. While the results of these studies are mixed, the majority of the interventions resulted in health benefits. Suggestions for future research are discussed.
