Health Behavior Change: Transtheoretical Model

Limitations

Vivian Ogbonnaya

HE 750-Behavioral and Social Foundations

  • Pre-contemplation stage and behavior change in young adults
  • Focuses mainly on the individual and their own decision-making skills
  • TTM research applied to reducing risks vs preventing risks

Self-efficacy

Confidence- that one can engage in health behavior across different challenging situations

Additional Components

What is the Transtheoretical Model ?

Temptation- to engage in unhealthy behavior across different challenging situations

Benefits of changing

Pros

Cons

Costs of changing

An integration of multiple processes and principles of major theories of intervention using stages of change

History

Developed by Prochaska et al (1977)

Theoretical Framework

  • Emerged from a comparative analysis of leading theories of psychotherapy and behavior change
  • Identified 10 processes that were predictive of successful quitting (DiClemente and Prochaska, 1982)

Initial Studies

  • Smoking
  • HIV/AIDS prevention
  • Alcohol/ substance abuse
  • Anxiety/ panic disorders
  • Mammography
  • Medication compliance

Critical Analysis

  • No one theory works for all complexities
  • Behavior change is a process that unfolds over time
  • Stages are stable and open to change
  • At-risk populations not prepared to take action
  • Emphasis of specific processes to increase effectiveness

Precontemplation- no intention to take action within the next 6 months

Contemplation- intend to take action within the next 6 months

Preparation- intends to take action within the next 30 days and has begun

Action- changed overt behavior for <6 months

Maintenance- changed overt behavior for more than 6 months

Termination- no temptation to relapse and 100% confidence
