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 ]
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 ...
[8] [9] The model focuses on the analysis of a behavior and then synthesizes the action to support the original behavior. [10] The model was changed after Richard J. Herrnstein studied the matching law of choice behavior developed by studying of reinforcement in the natural environment. More recently, the model has focused more on behavior over ...
A positivistic approach to behavior research, TRA attempts to predict and explain one's intention of performing a certain behavior.The theory requires that behavior be clearly defined in terms of the four following concepts: Action (e.g. to go, get), Target (e.g. a mammogram), Context (e.g. at the breast screening center), and Time (e.g. in the 12 months). [7]
The Information-Motivation-Behavioral Skills (IMB) model is a theoretical framework developed by Jeffrey D. Fisher and William A. Fisher in 1992. [1] Initially designed to understand and promote HIV -preventive behaviors, the IMB model has since been applied to various health-related behaviors and interventions.
By following 204 overweight men over the course of a three-month weight loss program, researchers applied a longitudinal, latent variable structural equation model to test SCT-related constructs including self-efficacy, outcome expectations, intention and social support as they apply toward self-reported changes in physical activity level.
