BACKGROUND The long-term impact and cost-effectiveness of weight management programmes depends on post-treatment weight maintenance. There is growing evidence that interventions based on third-wave cognitive behavioural therapy (3wCBT), specifically acceptance and commitment therapy (ACT), could improve long-term weight management however these interventions are typically delivered face-to-face by psychologists, which limits the scalability of this type of intervention. OBJECTIVE To use an evidence-, theory- and person-based approach to develop an ACT-based intervention for weight-loss maintenance that uses digital technology and non-specialist guidance to minimise resources needed for delivery at scale. METHODS Intervention development was guided by the Medical Research Council framework for the development of complex interventions in healthcare, Intervention Mapping Protocol, and the person-based approach for enhancing the acceptability and feasibility of interventions. Two phases of work were conducted: phase one consisted of collating and analysing existing and new primary evidence, and phase two consisted of theoretical modelling and intervention development. Phase one included a synthesis of existing evidence on weight-loss maintenance from previous research, a systematic review and network meta-analysis of 3wCBT interventions for weight management, a qualitative interview study of experiences of weight-loss maintenance, and the modelling of a justifiable cost for a weight-loss maintenance programme. Phase two included iterative development of guiding principles, a logic model and the intervention design and content. Target user and stakeholder panels were established to inform each phase of development and user-testing of successive iterations of the prototype intervention were conducted. RESULTS This process resulted in a guided self-help ACT-based intervention called SWiM (Supporting Weight Management). SWiM is a 4-month programme, consisting of weekly web-based sessions for 13 consecutive weeks, followed by a 4-week break for participants to reflect and practice their new skills, and a final session at week 17. Each session consists of psychoeducational content, reflective exercises, and behavioural experiments. SWiM includes specific sessions on key determinants of weight-loss maintenance, including developing skills to manage high-risk situations for lapses, creating new helpful habits, breaking old unhelpful habits, and learning to manage interpersonal relationships and their impact on weight-management. A trained, non-specialist coach provides guidance for participants through the programme with four scheduled 30-minute telephone calls and three further optional calls. CONCLUSIONS This comprehensive approach facilitated the development of an intervention that is based on scientific theory and evidence of how to support people with weight-loss maintenance, and is grounded in the experiences of the target users and the context in which it is intended to be delivered. The intervention will be refined based on findings of a planned pilot randomised controlled trial.

AbstractOverweight and obesity may increase risk of disease progression in men with prostate cancer, but there have been few studies of weight loss interventions in this patient group. In this study overweight or obese men treated for prostate cancer were randomised to a self-help diet and activity intervention with telephone-based dietitian support or a wait-list mini-intervention group. The intervention group had an initial group meeting, a supporting letter from their urological consultant, three telephone dietitian consultations at 4-week intervals, a pedometer and access to web-based diet and physical activity resources. At 12 weeks, men in both groups were given digital scales for providing follow-up weight measurements, and the wait-list group received a mini-intervention of the supporting letter, a pedometer and access to the web-based resources. Sixty-two men were randomised; fifty-four completed baseline and 12-week measurements, and fifty-one and twenty-seven provided measurements at 6 and 12 months, respectively. In a repeated-measures model, mean difference in weight change between groups (wait-list mini-intervention minus intervention) at 12 weeks was −2·13 (95 % CI −3·44, −0·82) kg (P = 0·002). At 12 months the corresponding value was −2·43 (95 % CI −4·50, −0·37) kg (P = 0·022). Mean difference in global quality of life score change between groups at 12 weeks was 12·3 (95 % CI 4·93, 19·7) (P = 0·002); at 12 months there were no significant differences between groups. Results suggest the potential of self-help diet and physical activity intervention with trained support for modest but sustained weight loss in this patient group.

Objective. Purely web-based weight loss and weight-loss maintenance interventions show promise to influence behavior change. Yet, little is known about user engagement with features of web-based interventions that predict clinically meaningful weight loss (≥5% bodyweight loss). This study examines level of website feature engagement with the likelihood of attaining ≥5% bodyweight loss after 6 and 18 months participation in a web-based intervention, among rural women at high risk of obesity-related diseases and disability. Methods. In this secondary analysis of clinical trial data of 201 rural women, we examined weight change and user engagement, measured as clicks on specific web-based intervention features (messaging and self-tracking), as associated with clinically meaningful weight loss (baseline to 6 months) and weight-loss maintenance (6 to 18 months). Results. Generalized estimating equations, adjusted for age, intervention group, and intervention phase, revealed high engagement with messaging predicted whether women achieved ≥5% weight loss at 6 months and at 18 months. There was no effect of self-tracking. Conclusions. Being engaged with messages was associated with attaining clinically meaningful short-term and longer-term weight loss. This trial is registered with NCT01307644.

BACKGROUND Many weight loss programs show short-term effectiveness, but subsequent weight loss maintenance is difficult to achieve. Digital technologies offer promising means to delivering behaviour change approaches at low cost and on a wide scale. The NoHoW project was a European Commission H2020-funded project aimed to develop, test, and evaluate a digital Toolkit designed to promote successful long-term weight management. The Toolkit was tested in an 18-month large-scale international 2 x 2 factorial (motivation and self-regulation versus emotion regulation) randomised controlled trial, conducted in overweight/obese adults who lost ≥5% of their body weight in the preceding twelve months before enrolment into the intervention. OBJECTIVE This paper describes the development of the NoHoW Toolkit focusing on the logic models, content and specifications, and results from user testing. METHODS The Toolkit was developed using a systematic approach including (1) development of the theory-based logic models, (2) selection of behaviour change techniques, (3) translation of these techniques into a digital web-based app (NoHoW Toolkit components), (4) technical development, (5) user evaluation and refinement of the Toolkit. RESULTS The Toolkit included a set of web-based tools and inputs from digital tracking devices (smart scales and activity trackers), with modules targeting weight, physical activity, and dietary behaviours. The final Toolkit was comprised of 34 sessions, distributed through 15 modules, providing active content over a 4-month period. The motivation and self-regulation arm consisted of 8 modules (17 sessions), the emotion regulation arm was presented with 7 modules (17 sessions), and the combined arm received the full Toolkit (15 modules, 34 sessions). The sessions included a range of implementations, such as videos, testimonies, and questionnaires. Further, the Toolkit contained 5 specific data tiles for monitoring weight, steps, healthy eating, mood and sleep. CONCLUSIONS A systematic approach to the development of digital solutions based on theory, evidence, and user testing, may significantly contribute to the advancement of the science of behaviour change and improve current solutions for sustained weight management. Testing the Toolkit using a 2x2 design provided a unique opportunity to examine the effect of motivation and self-regulation and emotion regulation separately, as well as the effect of their interaction in weight loss maintenance.
