Implication

Prospective cohort study demonstrates that readiness stages predict quitting success in smokers, highlighting the value of tailored cessation interventions.

Key Points

  • To test the transtheoretical model of change by evaluating how precontemplation, contemplation, and preparation stages relate to psychological characteristics and smoking cessation outcomes.
  • Categorized smokers into precontemplation (n = 166), contemplation (n = 794), and preparation (n = 506) stages of change.
  • Assessed baseline smoking history, 10 processes of change, pretest self-efficacy, and decisional balance.
  • Evaluated quit attempts and cessation success at 1-month and 6-month follow-up intervals.
  • Participants across all three stages demonstrated comparable smoking histories but differed substantially on current cessation activity.
  • Baseline stage of change significantly predicted subsequent quit attempts and successful smoking cessation at both 1-month and 6-month follow-up.
