Note. n=1340 individuals, n=2680 observations. HWLs – Health warning labels. The cut off point for low DS versus elevated DS was ≥ 7 at both waves using the CES-D7 scale. All main effect and interaction models adjust for age, sex, educational attainment, monthly household income, cigarettes per day, quit intention, quit attempt, and time in sample.
