  • Note: Models are adjusted for clinic- and provider-level clustering effects and all other variables in the column.

  • a “As a practitioner, how would you describe the importance you place personally on helping your patients quit smoking?” (Responses: 1–5 Likert scale, 1 = not important, 5 = extremely important)

  • b “Do you have... heart disease/ stroke/ heart failure/ cancer/ chronic obstructive pulmonary disease (COPD)?” (1 = yes, 0 = no for each condition)

  • c “Which of the following best describes your feelings about smoking right now?” (Responses: 1 = Ready to quit in next 30 days, 0 = Ready to quit in next 6 months or not ready to quit.)

  • d “On a scale of 1 to 10, how confident are you that you would be able to quit smoking at this time?” (1 = Not at all confident, 10 = Extremely confident.)
