Abstract

This study examined the effectiveness of two cancer prevention interventions in improving balanced diet among French children aged 12-14 years. The educational techniques used were taken from the taxonomy of behaviour change techniques (BCTs; Abraham & Michie, 2008). Allocation to intervention group (intervention versus control) was randomised at the school-level, the intervention group received two interventions, each of 1-h duration, containing BCTs including advocated attitude, anticipated success/regret, behaviour modelling and barrier identification. Self-reported diet was assessed pre- and post-interventions. The resulting data were coded by a nutritionist and transformed into a novel measure representing the extent to which the participant achieved a balanced diet. Multilevel modelling indicated that, having taken into account the clustered nature of the data, gender and the differing socio-economic status of the participants, balanced diet decreased over time, b=-1.23, t(1830)=-2.79, p=0.005, but this was qualified by a significant interaction effect with intervention, b=1.42, t(1830)=1.98, p=0.047. Separate models for each intervention group revealed that balanced diet decreased over time in the control group, b=-1.25, t(1195)=-2.47, p=0.014, but did not in the intervention group, b=0.19, t(635)=0.44, p=0.66, suggesting a buffering effect of the interventions on balanced diet over time. These findings demonstrate the effectiveness of educational interventions using established behaviour change techniques, to change behaviour.
