Overview of the
overview of the Transtheoretical Model
The Transtheoretical model is currently conceptualized in terms of
several major dimensions. The core constructs, around which the other dimensions are
organized, is the stages of change. These represent
ordered categories along a continuum of motivational readiness to change a problem
behavior. Transitions between the stages of change are effected by a set of independent
variables known as the processes of change. The
model also incorporates a series of intervening or outcome variables. These include decisional balance (the pros and cons of change), self-efficacy (confidence in the ability to change across
problem situations), situational temptations to engage in the problem behavior, and
behaviors which are specific to the problem area. Also included among these intermediate
or dependent variables would be any other psychological, environmental, cultural,
socioeconomic, physiological, biochemical, or even genetic variables or behavior specific
to the problem being studied.
