Effectiveness of behaviour change techniques in lifestyle interventions for non-communicable diseases: an umbrella review

Objective

To identify the most commonly reviewed behaviour change techniques (BCTs) and their effectiveness based on consistency across reviews for lifestyle interventions of non-communicable diseases.

Design

Umbrella review of systematic reviews.

Data sources

PubMed, Embase, PsycINFO, Cochrane CENTRAL, Global Health.

Data extraction and synthesis

A narrative synthesis of extracted findings was conducted. The Behaviour Change Technique v1 Taxonomy was used to identify and code behaviour change techniques (e.g., goal setting) in a standardised manner, which were independently assessed by two reviewers. Study quality was independently assessed by two reviewers using the assessment of multiple systematic review tools.

Results

26 reviews were included with a total of 72 BCT labels evaluated across the different lifestyle interventions and non-communicable diseases. A total of 13 BCT clusters were identified to be reported as effective. The most commonly reviewed BCTs and their effectiveness/ineffectiveness were as follows: ‘Goals and Planning’ (12 effective/1 ineffective), ‘Feedback and monitoring’ (9 effective/3 ineffective), ‘Social support’ (9 effective/1 ineffective), ‘Shaping knowledge’ (11 effective/1 ineffective), and ‘Natural consequences’ (6 effectiveness/ 2 ineffective). The vast majority of the studies were conducted in high-income and a few in upper middle-income countries, with hardly any studies from lower middle-income and lower income studies.

Conclusion

The most common BCTs were ‘Goals and Planning’, ‘Feedback and Monitoring’, ‘Shaping Knowledge’, ‘Social Support’, and ‘Natural Consequence’. Based on consistency across reviews, several BCTs such as ‘Goals and Planning’, Feedback and Monitoring’, ‘Shaping Knowledge’, and ‘Social Support’ have demonstrated effectiveness (Recommendation Grade A) in improving health behaviours across a limited range of NCDs. The evidence is less clear for other BCT techniques. It is also likely that not all BCTs will be transferable across different settings. There is a need for more research in this area, especially in low-middle-income countries.
