NC: Maintenance of Health/Behavior Change Following Short-term CBT (2008)
What is the evidence that cognitive-behavioral therapy of short-term duration (less than six months) targeted to weight management results in long-term maintenance of health or food behavior change in adults counseled in an outpatient or clinic setting?
One positive quality meta-analysis (29 RCTs), four neutral quality RCTs and three observational studies (one positive, one neutral, one negative quality) provide strong evidence that weight management treatment with diet and cognitive-behavioral therapy given in a six-month initial intervention period, results in modest weight loss after follow-up of at least 18 months post-treatment. Attrition rates increased the longer the follow-up was conducted. This is a common weakness of these studies that may result in outcome bias.
- Grade I means there is Good/Strong evidence supporting the statement;
- Grade II is Fair;
- Grade III is Limited/Weak;
- Grade IV is Expert Opinion Only;
- Grade V is Not Assignable.
- High (A) means we are very confident that the true effect lies close to that of the estimate of the effect;
- Moderate (B) means we are moderately confident in the effect estimate;
- Low (C) means our confidence in the effect estimate is limited;
- Very Low (D) means we have very little confidence in the effect estimate.
- Ungraded means a grade is not assignable.
