Footnotes

Table 1. Summary of important theories of behavioural change

Theory

Summary

Theory of reasoned action   

Human behaviour is under voluntary control. Intention to act is the most immediate determinant of behaviour and all other factors influencing behaviour will be mediated through this. Behavioural intentions are thought to be influenced by two factors, namely attitude and subjective norm.

Theory of planned behaviour

An extension of the theory of reasoned action that includes measures of control belief and perceived behavioural control, considered as being a third influence on behavioural intentions.

Trans‐theoretical model

Behaviour change is a process rather than a single event. People do not change all at once, rather they move through a series of five stages: pre‐contemplation, contemplation, preparation, action and maintenance.

Social cognitive theory

Health choices people make are related to outcome expectancies (whether an action will lead to a particular outcome) and self‐efficacy (whether they believe that they can change).
