Abstract
Objectives
Theoretical models have informed the understanding of pregnancy as a ‘teachable moment’ for health behaviour change. However, these models have not been developed specifically for, nor widely tested, in this population. Currently, no pregnancy-specific model of behaviour change exists, which is important given it is a unique yet common health event. This study aimed to assess the extent to which factors influencing antenatal behaviour change are accounted for by the COM-B model and Teachable Moments (TM) model and to identify which model is best used to understand behaviour change during pregnancy.
Design
Theoretical mapping exercise.
Methods
A deductive approach was adopted; nine sub-themes identified in a previous thematic synthesis of 92 studies were mapped to the constructs of the TM and COM-B models. The sub-themes reflected factors influencing antenatal health behaviour.
Findings
All sub-themes mapped to the COM-B model constructs, whereas the TM model failed to incorporate three sub-themes. Missed factors were non-psychological, including practical and environmental factors, social influences, and physical pregnancy symptoms. In contrast to the COM-B model, the TM model provided an enhanced conceptual understanding of pregnancy as a teachable moment for behaviour change, however, neither model accounted for the changeable salience of influencing factors throughout the pregnancy experience.
Conclusions
The TM and COM-B models are both limited when applied within the context of pregnancy. Nevertheless, both models offer valuable insight that should be drawn upon when developing a pregnancy-specific model of behaviour change.
