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.
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 Andersen healthcare utilization model is a conceptual model aimed at demonstrating the factors that lead to the use of health services. According to the model, the usage of health services (including inpatient care, physician visits, dental care etc.) is determined by three dynamics: predisposing factors, enabling factors, and need.
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 ...
Models of abnormality are general hypotheses as to the nature of psychological abnormalities. The four main models to explain psychological abnormality are the biological, behavioural, cognitive, and psychodynamic models. They all attempt to explain the causes and treatments for all psychological illnesses, and all from a different approach.
Recent advances in psychological, medical, and physiological research have led to a new way of thinking about health and illness. This conceptualization, which has been labeled the biopsychosocial model, views health and illness as the product of a combination of factors including biological characteristics (e.g., genetic predisposition), behavioral factors (e.g., lifestyle, stress, health ...
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.
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.
