Behavioural and cognitive-behavioural theories in oral health research: Current state and future directions.

OBJECTIVES: Behavioural and cognitive-behavioural theories, models and frameworks have been incorporated for decades in behavioural and social oral health sciences, oral health care, and education of dentists, hygienists, and other oral healthcare professionals.

METHODS: While a myriad of these conceptualizations have been incorporated in this work, there are six of them that have had the greatest impact in the oral health arena: (a) Health Belief Model; (b) Theory of Reasoned Action, Theory of Planned Behavior and Integrated Behavioral Model, which are considered in unison; (c) Social Learning Theory and Social Cognitive Theory which are considered together; (d) Transtheoretical Model/Stages of Change Model; (e) Salutogenesis Model/Theory and Sense of Coherence Framework; and the (f) Behavior Change Wheel, Capability-Opportunity-Motivation-Behavior Model and Theoretical Domains Framework, which are categorized together.

RESULTS: An analysis of nomenclature (i.e. theories, models, frameworks and conceptualizations) is provided in the context of a description of each of these theories and models, with discussion about their aspects that particularly relate to oral health. Additionally, a quantitative, longitudinal view is provided of the frequency of use of these theories and models in the oral health arena. Given the benefits of theory-based intervention development, dissemination and implementation, it is important to consider these theories and models in a collective context.

CONCLUSIONS: At a basic level, these theories and models help in identifying and acting on mechanisms, both of behaviour itself and behaviour change. Future directions are discussed in terms of need for theory evolution and development.
