Note. CPD = average cigarettes smoked per day—Smoking History Questionnaire (SHQ; Brown et al., 2002); diagnosis = current Axis I diagnosis, dummy coded (no = 0; yes = 1), per Structured Clinical Interview-Non-Patient Version for DSM-IV (SCID-I-NP; First et al., 1994); sex = dummy coded (1 = males; 2 = females); PA Hx = two-year history of panic attacks, dummy-coded (no = 1, yes = 2), per SCID-I-NP (First et al., 1994); ASI-III = Anxiety Sensitivity Index-III-Total Score (Taylor et al., 2007); SCQ-NR = Smoking Consequences Questionnaire-Negative Reinforcement/Negative Affect Reduction Subscale (Brandon & Baker, 1991); RFS-AD = Reasons for Smoking-Addictive Subscale (Ikard et al., 1969); RFS-NA = Reasons for Smoking-Negative Affect Subscale (Ikard et al.,1969); BCS = Barriers to Cessation Scale-Total Score (Macnee & Talsma, 1995a); Quit probs = composite score of problematic symptoms experienced during quitting—SHQ (Brown et al., 2002).
