SWiM (Supporting Weight Management) Feasibility Study
After weight loss, people often find it difficult to maintain their new weight and many regain the weight that they lost. Growing evidence suggests that interventions based on acceptance and commitment therapy (ACT) may be more effective than standard treatments for longer-term weight control.
The SWiM (Supporting Weight Management) feasibility study is testing a new online acceptance-based intervention to investigate whether this helps people to maintain their weight loss, and improve their physical and mental health, compared to standard treatment.
Starting in April 2021, we will recruit 60 adults who have recently completed a weight loss programme. Two thirds of participants (40 adults) will receive a new online weight loss maintenance intervention called SWiM (“Supporting Weight Management”), which includes telephone support from a coach. SWiM is a guided self-help programme based on ACT and will teach new skills and strategies to help people maintain their new weight over the long term.
One third of participants (20 adults) will receive a booklet designed to help create a personalised weight maintenance plan, with helpful hints and tips for keeping the weight off.
All participants will be asked to complete online questionnaires at the beginning of the study and 6 months later. At the end of the study, we will compare changes in weight and other outcomes between the two groups. A small sample of participants will also be invited to take part in interviews with researchers online or over the telephone to help us learn about their experiences of the interventions.
