Note. Analyses were conducted with full maximum likelihood estimation using PROC MIXED in SAS. Time-varying abstinence refers to seven-day point-prevalence smoking abstinence versus nonabstinence at the assessment concurrent with the assessment of depressive symptoms (CES-D). Analyses included all participants with any data on the CES-D; one participant was not included due to missing data on MDD history. CES-D = Center for Epidemiologic Studies Depression Scale; FTND = Fagerström Test for Nicotine Dependence; MDD = major depressive disorder; ST = standard treatment; ST-BI = standard treatment plus brief alcohol intervention.
