Abstract
BackgroundMeta-analyses have identified promising behavior change techniques (BCTs) in changing obesity-related behaviors from intervention descriptions. However, it is unclear whether these BCTs are used by intervention participants and are related to outcomes.PurposeThe purpose of this study is to investigate BCT use by participants of an intervention targeting physical activity and diet and whether BCT use was related to behavior change and weight loss.MethodsIntervention participants (N = 239; 40–69 years) with recently diagnosed type 2 diabetes in the ADDITION-Plus trial received a theory-based intervention which taught them a range of BCTs. BCT usage was reported at 1 year.ResultsThirty-six percent of the participants reported using all 16 intervention BCTs. Use of a higher number of BCTs and specific BCTs (e.g., goal setting) were associated with a reduction in body mass index (BMI).ConclusionsBCT use was associated with weight loss. Future research should identify strategies to promote BCT use in daily life.

Highlights
Meta-analyses have identified promising behavior change techniques (BCTs) in changing obesity-related behaviors from intervention descriptions
The current study focuses on the association between enactment of BCTs and behavioral and clinical outcomes among participants in the intervention arm of the ADDITION-Plus trial [15] who were recently diagnosed with type 2 diabetes
The aim of this study is to investigate whether reported use of behavior change techniques (BCTs) taught in a theory-based behavioral intervention is associated with change in objectively measured and self-reported physical activity (PA) and dietary behaviors and weight loss
