Note. N = 1365. For each outcome, combined models were conducted including all six simultaneous predictors. Significant effects (p < .05) are bolded.

^aIncludes only individuals who achieved initial abstinence (n = 1205).

^bIncludes only individuals who lapsed (n = 892).

^cLogistic regression model.

^dCox proportional hazards regression survival model.

^eModels adjusted for only treatment (dummy coded to categorize all six conditions).

^fStandardized Multidimensional Personality Questionnaire—Brief Form scores (M = 0, SD = 1).

^gModels adjusted for treatment (dummy coded to categorize all six conditions), age, gender, ethnicity and Fagerström Test of Nicotine Dependence score.

^hEffect significant after holm correction within the family of tests for that predictor.
