INTERPRETATION In type 2 diabetes , there are improvements in long-term glycaemic control and psychological distress but not in weight control or blood glucose concentration in people who receive psychological therapies
BACKGROUND Adherence difficulties and psychological problems are associated with poor glycaemic control  in diabetes .
We undertook a systematic review and meta- analysis of psychological therapies to assess their effectiveness in improving glycaemic control in type 2 diabetes .
A Randomized Clinical Trial Comparing Behavior Modification and Individual Counseling in the Nutritional Therapy of Non-insulin-dependent Diabetes Mellitus: Comparison of the Effect on Blood Sugar, Body Weight, and Serum Lipids
To determine whether a group behavior modification approach might be preferable to individual counseling in the nutritional therapy of non-insulin-dependent diabetes mellitus , 40 adults younger than 65 yr of age with diabetes mellitus who were not receiving insulin were r and omized to either a program of individualized dietary review and recommendations or a program of group meetings aim ed at controlling the signals leading to overeating and noncompliance with a diabetic dietary regimen . Statistically significant ( P < 0.05 ) decreases in body weight , sum skin-fold thickness , fasting serum glucose , and serum triglycerides but not LDL-C or HDL-C were observed . The individual counseling group had a greater amount of weight loss than the behavior modification group . There were no significant ( P < 0.05 ) differences between the two groups with respect to the biochemical outcome variables . Patient characteristics assessed at entry — namely anxiety , internal versus external locus of control and perceived disease severity , and compliance with advice — were significantly associated with weight loss in the behavior modification group while only the latter index was of value in the individual counseling group . Thus , our use of these programs does not identify a clear advantage of either approach in the nutritional therapy of non-insulin-dependent diabetic patients
