A qualitative data-prompted study of weight loss maintenance experiences using individual ecological data

Abstract

Background: This study aimed to advance understanding of psychological and contextual variables associated with weight loss maintenance (WLM). Methods: Semi-structured, data prompted interviews were conducted with people who lost over 5% of their body weight in the previous year. For two months participants gathered WLM relevant data through ecological momentary assessment using online delivered surveys, WiFi connected activity monitors and scales, and through experience sampling. During the interview, participants were presented with reports based on their own data including weight and activity graphs; correlations of psychological factors; self-generated real time notes; and pictures. The data was analysed using the Framework method. Findings: Twelve participants were interviewed after 2 months (mean age 50.58, SD=9.92; 3M, 9F). Five main themes associated with successful WLM emerged from the data: (1) change in motivation, (2) shift from effortful self-regulation towards (3) habit formation, (4) relying on plentiful cognitive resources, and (5) supportive environment. Discussion: This study used mobile and wireless devices to obtain data that was used to stimulate narratives and to explore WLM.
