Investigating the effect of an online self-compassion for weight management (SC4WM) intervention on self-compassion, eating behaviour, physical activity and body weight in adults seeking to manage weight: protocol for a randomised controlled trial.

Abstract

<h4>Introduction</h4>Individual weight management, defined as engaging in behaviours to maintain or lose weight, can improve health and well-being. However, numerous factors influence weight management outcomes, such as genetics, biology, stress, the social and physical environment. Consequently, weight management can be hard. Self-compassion, described as treating oneself kindly in times of failure or distress, has shown promise in improving weight management outcomes. The objectives of this study are twofold: (1) to examine the efficacy of an online self-compassion for weight management (SC4WM) intervention coupled with an online commercial weight management programme (WW Weight Watchers reimagined) with increasing self-compassion and improving weight management outcomes (eating behaviour, physical activity and body weight) in comparison with the WW programme only and (2) to explore whether improvements in weight management outcomes are moderated by eating restraint, weight self-stigma, perceived stress and psychological coping.<h4>Methods and analysis</h4>To achieve these objectives, 240 participants seeking to manage their weight were randomised to either an online behavioural commercial weight management programme (WW) or the online WW +SC4 WM intervention. Validated measures of self-compassion, stress, weight self-stigma, eating restraint, psychological coping and weight management outcomes were administered online at baseline, 4 weeks and at a 12-week follow-up.<h4>Ethics and dissemination</h4>Ethics has been granted by the University of Auckland Health Research Ethics committee. Results will be communicated in peer-review journals, conferences and a doctoral thesis. If effective in increasing self-compassion and improving weight management outcomes, the intervention could be made more widely available to supplement behavioural weight management programmes.<h4>Trial registration number</h4>ACTRN12621000580875; Pre-results.
