Transtheoretical (staircase) Model conceptualizes which of the following?

• A. An integrated biomedical model of disease progression
• B. A theory of environmental modification only
• C. A stepwise, integrated model of intentional behavioral change
• D. A model for random behavior change

Answer: (C)

Change is viewed as a progression through distinct stages of readiness, with the person actively planning and applying strategies to move forward. The Transtheoretical Model presents a stepwise, integrated framework that ties together where someone is in their willingness to change with the processes they use to advance—cognitive, behavioral, and experiential techniques—along with factors like self-efficacy and the pros and cons of changing. This makes behavior change appear as a purposeful, gradual journey, not a random occurrence or something driven solely by the environment. The model also accommodates relapse and recycling through stages, reflecting real-world process of maintaining new behaviors. That’s why it best describes a stepwise, integrated model of intentional behavioral change. It isn’t a biomedical disease progression model, nor is it solely about environmental modification, nor is change represented as random.
