“…Studies were published between 1980 and 2017 (five in 1980s, one in 90s and four since 2010) in the USA ( n = 7), Denmark [38], India [39] and Japan [40], with a total of 1320 participants (see Table 1). Seven studies took place within community settings, two took place in the workplace [38, 40] and one home intervention [41]. Six studies reported mean age, ranging from 30 to 59 years [36, 38, 40–43].…”

“…All but one study [44] reported gender: of the 1214 participants, 1041 (86%) were female. Four studies exclusively recruited women [39, 41, 43, 45], one recruited only men [40]. In terms of commitment device type, eight studies reported the use of behavioural contracts (1.8 BCTTv1), one specified the use of verbal commitments (1.9) by male spouses of female participants in addition to the contracts [43], one described an online/app based pledge [38], and one reported a public commitment to an outcome (rather than a behaviour) [39].…”

The effect of commitment-making on weight loss and behaviour change in adults with obesity/overweight; a systematic review

Background Adherence to weight loss interventions is crucial to successful outcomes, yet little is known about how best to improve it. This suggests a need for developing and improving adherence strategies, such as formal commitments. This review aims to identify the effect of including a commitment device alongside lifestyle interventions on weight loss, and identify the most appropriate delivery mechanisms and target behaviours. Methods We searched five databases and hand-searched reference lists for trials of behavioural interventions to achieve weight loss among adults with excess weight or obesity. Interventions incorporating commitment devices were included in a narrative review and meta-analysis where appropriate. Commitment devices with financial incentives were excluded. Results Of 2675 unique studies, ten met the inclusion criteria. Data from three randomised trials including 409 participants suggests that commitment interventions increases short-term weight loss by a mean of 1.5 kg (95% CI: 0.7, 2.4). Data from two randomised trials including 302 patients suggests that benefits were sustained at 12 months (mean difference 1.7 kg; 95% CI: 0.0, 3.4). Commitment devices appeared most successful when made publicly, and targeting diet rather than physical activity. Conclusions Using commitment devices, such as behavioural contracts, as part of a weight loss intervention may be useful in improving weight loss outcomes and dietary changes, at least in the short-term. However, evidence is limited and of variable quality so results must be interpreted with caution. Poor reporting of intervention details may have limited the number of identified studies. More rigorous methodology and longer term follow-ups are required to determine the effectiveness of behavioural contracts given their potential for use in public health interventions.

Background: The United States Department of Health and Human Services (USDHHS)recommends that adults achieve 150 minutes per week of moderate-intensity aerobic activity.Most African American women do not meet these guidelines. The purpose of this study was to determine the efficacy of an intervention based on the fourth generation, multi-theory model (MTM) of health behavior change for initiating and sustaining physical activity among African American women when compared to a first generation, knowledge-based intervention. Methods: The randomized controlled trial (RCT) utilized a pre-test, post-test and 6-week followup evaluation with an experimental (n=25) group and a comparison group (n=23). Process evaluation for satisfaction and program fidelity was conducted along with impact evaluation for changes in MTM constructs, intent to initiate and sustain physical activity, minutes of physical activity, body mass index (BMI), waist circumference and blood pressure in hypertensives. Results:The MTM-based intervention proved significantly efficacious in increasing the minutes of physical activity from pre-test mean of 37 minutes to 172 minutes at follow-up (mean difference135.08 minutes, 95% CI: 106.04 to 164.13, P<0.0001), reducing waist circumference from pretest mean of 39 inches to 38 inches at follow-up (mean difference -1.12 inches, 95% CI: -1.70 to-0.545, P<0.001) and modifying the MTM construct of changes in physical environment from a mean of 7 units at pre-test to 9 units at follow-up (mean difference 2.08 units, 95% CI: 0.73 to 3.43, P<0.004) when compared to the knowledge-based intervention over time. Conclusion: There were directional improvements in the mean scores for most of the study variables over time for the MTM intervention group and statistically significant improvement in minutes of physical activity and waist circumference.

“…Mechanization of industries, like agriculture, has led to less physical activity among rural men. Poor food quality, excessive calorie consumption, eating while doing other activities, and culturally rooted community characteristics contribute to unhealthy rural diets (Chrisman, Nothwehr, Yang, & Oleson, ; Kegler et al., ). Rural men have chronicled health disparities (e.g., environmental‐structural barriers, lack of preventive services, high obesity prevalence) that serve as public health threats to this hard‐to‐reach population (Meit et al., ).…”
