Which model is described as the one that conceptualizes the process of intentional behavioral change?

• A. Health Promotion Model
• B. Health Promoting Behavior
• C. Social Cognitive Theory
• D. Transtheoretical (staircase) Model

Answer: (D)

This item tests understanding that intentional change unfolds in stages. The Transtheoretical (staircase) Model describes a stepwise progression through readiness to change: precontemplation, contemplation, preparation, action, and maintenance, with relapse as part of cycles. Change is seen as a deliberate, planned process, not a one-time act. It also highlights processes of change—cognitive and behavioral strategies people use to move from one stage to the next.

This is the best fit because it directly models how people progress toward adopting new behaviors over time, tailoring interventions to a person’s current stage and the strategies that help them advance. In contrast, other models focus more on overall motivation and determinants of health-promoting behavior (not the staged change process) or on reciprocal influences and self-efficacy without delineating a stage-based path of change. The Transtheoretical Model is especially useful for guiding stepwise interventions in practices like smoking cessation or starting an exercise routine.
