Indirect Effects for Longitudinal Mediation Analyses

	(T1)	(T1)	(T2)	Indirect Effect		Total Effect
				Effect Size	BC Bootstrap CI	Effect Size
H2a	Exposure	→ Talk about quitting	→ Sought help	.013	−.001 – .031	.122
H2b	Exposure	→ Talk about quitting	→ Tried to quit	.010	−.004 – .028	.077
H3a	Talk about ads	→ Talk about quitting	→ Sought help	.037	.013 – .070	.095
H3b	Talk about ads	→ Talk about quitting	→ Tried to quit	.037	.008 – .072	.074

Note. n = 608–802 (varies across analyses due to missing data on confounders and talk about ads variable). T1 = variable measured at first interview; T2 = variable measured at three-month follow-up interview; BC Bootstrap CI = bias-corrected bootstrap confidence intervals. Indirect and total effect sizes are standardized. Non-zero indirect effects are bolded. These analyses report the effects of the compound path from the first named variable to the last named variable through the mediator, adjusting for the effects of the prior level of the outcome and all confounders. Behavioral outcomes occurred within the past three months.
