The effect of commitment-making on weight loss and behaviour change in
adults with obesity/overweight; a systematic review.
BMC Public Health. 2019 Jun 24;19(1):816

Abstract
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.
