Application of Social and Behavioral Theories in Public Health Interventions

4. Important Theories and Their Key Constructs

Exercise 2

This exercise asks the user to evaluate statements about the Transtheoretical/Stages of Change Model (TTM).

Instructions:
Decide whether each of the following statements about the Transtheoretical/Stages of Change Model (TTM) is true or false.

Statements:
1.  Anyone is ready to make changes in health behavior.
2.  The TTM can be used to explain or predict changes in health behavior.
3.  According to the TTM, the progression through the stages of change must be linear.

Answers:
1.  Anyone is ready to make changes in health behavior.
[False] This is not true.  According to the TTM, people are at varying stages of change; some people may not be ready to make changes, while others have already begun changes.

2.  The TTM can be used to explain or predict changes in health behavior.
[True] This is true.  TTM has been examined in health behavior research and found useful in explaining and predicting changes in behavior- for example: smoking, physical activity, and eating.

3.  According to the TTM, the progression through the stages of change must be linear.
[False] It is common for one to recycle through stages or revert back to an earlier stage throughout the process.  Although the stages themselves are linear, progression through them is not necessarily so.
