Theories of Behaviour Change

Understanding Theories of Behaviour Change

• Theories of behaviour change aim to understand, predict and influence behaviour change, especially relating to health.
• These theories seek to pinpoint the factors and processes that encourage or discourage changes in health behaviour.
• They often focus on concepts such as motivation, self-efficacy, social influence, and the benefits and costs of change.
• Applying these theories can help design effective interventions to promote healthier behaviours.

Key Theories of Behaviour Change

• Social Learning Theory (SLT): Proposed by Bandura, this theory suggests that people learn from others through observing, imitating, and modelling behaviour. This theory emphasises reciprocal determinism, where the individual, the behaviour, and the environment interact and influence one another.
• Health Belief Model (HBM): This model suggests that behaviour change is influenced by perceived susceptibility to a health problem, perceived severity of the problem, perceived benefits of action, and barriers to taking that action.
• Theory of Reasoned Action (TRA) and Theory of Planned Behaviour (TPB): Both theories propose that individual behaviour is driven by behavioural intentions. TRA focuses on attitudes and subjective norms, while TPB adds the role of perceived behavioural control.
• Transtheoretical Model (TTM): This model views behaviour change as a process that occurs in stages - precontemplation, contemplation, preparation, action, maintenance, and termination. It incorporates strategies and processes to move between stages.

Implications of Behaviour Change Theories in Health and Social Care

• Behaviour change theories can form the basis for health promotion interventions, by understanding and influencing factors that drive behaviour change.
• They can be used to tailor interventions to individuals or groups, considering their motivations, perceived barriers, self-efficacy, and readiness to change.
• These theories can support the development of strategies to enhance adherence to recommended health behaviours such as medication use, physical activity, or diet.
• They can contribute to the training of health and social care professionals by equipping them with a psychological understanding of behaviour change.

Remember: Theories of Behaviour Change are crucial frameworks in understanding and promoting the transition from unhealthy to healthy behaviours. They acknowledge the complexity of behaviour change and propose a multifaceted approach to promoting health and preventing illness.
