Effectiveness of cCBT-Based Ecological Momentary Intervention vs. Diet-Only for Obesity

Importantly, it should be noted that ethical approval was obtained from the standing ethical committee of the Faculty of Psychology and Neuroscience (FPN) of Maastricht University. The METC of the Maastricht Academic hospital and FPN have an agreement on which research proposals can be evaluated by the faculty ethical committee and which ones have to be forwarded to the METC.



This trial will investigate the effectiveness of a momentary assessment-based intervention (Think Slim) that includes a cCBT for obesity protocol delivered via the internet and smartphone. Of particular interest is the effectiveness of Think Slim to reduce post-intervention weight regain.

Relative to a diet-only wait-list control condition, cCBT-Based Ecological Momentary Intervention is more effective at...



(1) ...achieving (sustained) weight loss, also at a 3-month and 1-year follow-up.

(2) ...reducing eating-related dysfunctional cognitions.

(3) ...establishing healthier eating patterns.

6 Weeks of cCBT preceded and followed by 1 week of Ecological Momentary Assessment

(1) Computerized Cognitive Behavioural Therapy (cCBT) for Obesity provided as an Ecological Momentary Intervention (EMI), with no therapist involvement + Calorie-restricting diet

(2) Calorie-restricting diet only
