Notes: Time is centered at assessment 1 (i.e., quit day). The other continuous predictors were centered at their mean. LMM = linear mixed-effects models; crav. = craving; irrit. = irritability; frust. = frustration; anx. = anxiety; conc. = concentration; restl. = restlessness; appet. = appetite; depress. = depression; insom. = insomnia; FTND = Fagerström Test for Nicotine Dependence; ASI = Anxiety Sensitivity Index; MASQ-AD = Mood and Anxiety Symptom Questionnaire–anhedonic depression subscale.
