Uitkomstmaten
Primaire uitkomstmaten
The primary endpoint with respect to the efficacy of CPI, is the between-group difference in weight change (kg) measured as weight after 2 years follow-up minus weight at week 12 (directly after intervention).
Achtergrond van het onderzoek
In this randomized controlled trial we investigate the effectiviness of adding a Combined Psychological Intervention to a very low calorie diet, as compared to usual care, in maintaining weight loss and improving glycaemic, cardiovascular and psychological parameters in patients with type 2 diabetes and overweight.
Doel van het onderzoek
Adding a Combined Psychological Intervention to a very low calorie diet is more effective then a very low calorie diet followed by usual care in maintaining weight loss and improving glycaemic control, cardiovascular risk score, psychological variables and quality of life in patients with diabetes type 2.
Onderzoeksopzet
Outcome measurments at baseline, week 23 (after intervention), 1 year, 1,5 years and 2 years.
Onderzoeksproduct en/of interventie
1. Very low calorie diet + usual care;
2. very low calorie diet + usual care + Combined Psychological Intervention (CPI).
The first 8 weeks, a very low calorie diet will be given, consisting of 750 calories a day. After these 8 weeks, the diet will become less low, building up to 1300 calories a day in 2x 8 weeks.
After the first 8 weeks, randomisation will take place. Only participants who lost more than 5% of their body weight will be randomised.
CPI: An integrated multimodel group treatment, consists of cognitive restructuring, Problem Solving Therapy and Proactive Coping. During the first 10 weeks there will be a weekly session of 1,5 hours. After those 10 weeks, the session will become less frequent. A total of 17 sessions is planned.
