The Transtheoretical Model was developed by Prochaska and DiClemente in the 1970s, it took shape after studies were analyzed that observed the experiences of smokers who quit without intervention versus those needing treatment. It was concluded that individuals stopped smoking only when they were ready to. Following this observation, the Transtheoretical Model (TTM) centers on the decision-making of the individual person and is a model of intentional change. The TTM works on the assumption that individuals don’t alter behaviors abruptly and conclusively. Instead a change in behavior, particularly habitual behavior, happens continuously via a cyclical process. The TTM is a model, as opposed to a theory; therefore different behavioral theories and constructs can be applied to various phases of the model where they can be effective (Glanz et al., 2008).The TTM also incorporates a list of outcome variables: decisional balance, self-efficacy, behaviors and any other psychosocial or biological variables that might help to describe the specific area of change.
The TTM suggests that individuals go through six stages of behavior change: precontemplation, contemplation, proposes preparation, action, maintenance, and termination. Termination wasn’t originally part of the model and is used less often in presentation of the stages of change for health-related behaviors.
Precontemplation - Where there is no intent to change-- in this stage, the individual does not intend to take any action within the next 6 months. People are often not aware that their behavior produces damaging consequences. In this stage, people may underestimate the pros of changing behavior and place a much larger emphasis on the cons of changing behavior.

...h use a continuum—they both see behavior change as a fluid, rebounding endeavor with thought and intent put in at various points. They both also mistakenly assume that individuals always put coherent and logical thought into their behaviors.
Possible Efficacy in Dietary Change. TTM is a model, a description of behavior, and is good for assessing an individual’s current stage of behavior change. SCT is a theory and blends ideas from cognitive, behavioral and emotional descriptions of behavior and can be applied to counseling. Therefore, combing the two in order to facilitate dietary change may be a beneficial plan. SCT has been shown to be a good fit with data with regards to dietary change (Anderson, et al., 2007). Results may be improved my deciphering where an individual is in the TTM continuum and tailoring their counseling according to the constructs of SCT
