Limitations of the transtheoretical model
-The theory ignores the social context in which change occurs, such as income..
-The lines between the stages can be arbitrary with no set criteria of how to determine a person's stage of change. The questionnaires that have been developed to assign a person to a stage of change are not always standardized or validated.
-There is no clear sense for how much time is needed for each stage, or how long a person can remain in a stage.
-The model assumes that individuals make coherent and logical plans in their decision-making process when this is not always true.
-The Transtheoretical Model makes no assumption about how ready individuals are to change. (uri.edu)
-The Transtheoretical Model is applicable to only a single unhealthy behavior and does not consider the impact of other confounding health behaviors.
-The Model is applicable only as an enhancement for thinking about change
-The Transtheoretical Model does not address the biological, environmental, or social issues related to change in health behaviors
-The Model does not differentiate between patients who are able to make lifelong change and those who are not.
