Each behavioural change theory or model focuses on different factors in attempting to explain behaviour change. Of the many that exist, the most prevalent are learning theories, social cognitive theory, theories of reasoned action and planned behaviour, transtheoretical model of behavior change, the health action process approach, and the BJ Fogg model of behavior change.
Behavior change, in context of public health, refers to efforts put in place to change people's personal habits and attitudes, to prevent disease. [1] Behavior change in public health can take place at several levels and is known as social and behavior change (SBC). [2]
Models that describe health behavior change can be distinguished in terms of the assumption whether they are continuum-based or stage-based. [7] A continuum (mediator) model claims that change is a continuous process that leads from lack of motivation via action readiness either to successful change or final disengagement.
The health belief model (HBM) is a social psychological health behavior change model developed to explain and predict health-related behaviors, particularly in regard to the uptake of health services. [1] [2] The health belief model also refers to an individual's beliefs about preventing diseases, maintaining health, and striving for well-being ...
The transtheoretical model is also known by the abbreviation "TTM" [2] and sometimes by the term "stages of change", [3] although this latter term is a synecdoche since the stages of change are only one part of the model along with processes of change, levels of change, etc. [1] [4] Several self-help books—Changing for Good (1994), [5 ...
Policy for population health "sets priorities" [2] and are a "guide to action to change what would otherwise occur". [2] Policies are based on "social sciences of sociology, economics, demography, public health, anthropology, and epidemiology" [4] and determine how outcomes can be accomplished are implemented at various levels. Such guides ...
These determinants are included in theories of behavior explanation such as the reasoned action approach and health belief model. Other theories explain how such determinants may be changed, such as the social cognitive theory (which is in fact also a theory to explain behavior), the elaboration likelihood model, and the extended parallel ...
In psychology, the I-change model [1] [2] or the integrated model, for explaining motivational and behavioral change, derives from the Attitude – Social Influence – Self-Efficacy Model, integrates ideas of Ajzen's Theory of Planned Behavior, [3] Bandura's Social Cognitive Theory, Prochaska's Transtheoretical Model, [4] the Health Belief Model, [5] and Goal setting [6] theories.
