Transtheoretical Model/Stages of Change Model

Precontemplation

No considering change. Unaware or resistant to change.

Contemplation

Thinking about change. Ambivalent but aware.

Preparation

Getting ready to change. Making small changes.

Action

Actively changing behavior within the past 6 months.

Maintenance

Sustaining behavioral change beyond 6 months

Termination

No temptation tp relapse; full confidence in ability to stick with change. Often omitted in PA contexts.

Key Stimuli for Precontemplation to Contemplation

• Consequences become unavoidable

• External pressure or feedback from others

• Unpleasant emotions (dissatisfaction or feeling stuck)

• Exposure to new information or role models

• A moment of clarity or turning point that often carries emotional weight

Decisional Balance

Weighing pros and cons of changing behavior. Change is more likely when pros of change outweigh the cons.

Relapse

Behavior change is not linear; people relapse and re-enter earlier stages. Normalize relapse as apart of the process.
