Reflections on the Continued Popularity of the Transtheoretical Model

Sometimes in health behavior research, purportedly novel theoretical models are offered that may help move thinking about behavior change forward, and may be well-received by clinicians, but over time end up being a subject of continual scientific disconfirmation. The transtheoretical model is one rather popular example. The five stages of change and associated 10 processes of change are well-known (e.g., DiClemente et al., 2008; DiClemente et al., 2004). Yet, the model has been discredited to a large extent by several in the health behavior research community. In the present editorial, we briefly summarize the transtheoretical model, mention its current ongoing popularity, identify the critiques of this model, and suggest how one might best consider the model in future health behavior research and practice.
