Dagens #fsvoversigt:
The effectiveness of financial incentives for health behaviour change:
systematic review and meta-analysis.
PLoS One. 2014;9(3):e90347
Authors: Giles EL, Robalino S, McColl E, Sniehotta FF, Adams J
Abstract
BACKGROUND: Financial incentive interventions have been suggested as one method
of promoting healthy behaviour change.
OBJECTIVES: To conduct a systematic review of the effectiveness of financial
incentive interventions for encouraging healthy behaviour change; to explore
whether effects vary according to the type of behaviour incentivised,
post-intervention follow-up time, or incentive value.
DATA SOURCES: Searches were of relevant electronic databases, research
registers, www.google.com, and the reference lists of previous reviews; and
requests for information sent to relevant mailing lists.
ELIGIBILITY CRITERIA: Controlled evaluations of the effectiveness of financial
incentive interventions, compared to no intervention or usual care, to
encourage healthy behaviour change, in non-clinical adult populations, living
in high-income countries, were included.
STUDY APPRAISAL AND SYNTHESIS: The Cochrane Risk of Bias tool was used to
assess all included studies. Meta-analysis was used to explore the effect of
financial incentive interventions within groups of similar behaviours and
overall. Meta-regression was used to determine if effect varied according to
post-intervention follow up time, or incentive value.
RESULTS: Seventeen papers reporting on 16 studies on smoking cessation (n =
10), attendance for vaccination or screening (n = 5), and physical activity (n
= 1) were included. In meta-analyses, the average effect of incentive
interventions was greater than control for short-term (≤ six months) smoking
cessation (relative risk (95% confidence intervals): 2.48 (1.77 to 3.46);
long-term (>six months) smoking cessation (1.50 (1.05 to 2.14)); attendance for
vaccination or screening (1.92 (1.46 to 2.53)); and for all behaviours combined
(1.62 (1.38 to 1.91)). There was not convincing evidence that effects were
different between different groups of behaviours. Meta-regression found some,
limited, evidence that effect sizes decreased as post-intervention follow-up
period and incentive value increased. However, the latter effect may be
confounded by the former.
CONCLUSIONS: The available evidence suggests that financial incentive
interventions are more effective than usual care or no intervention for
encouraging healthy behaviour change.
