*p < .05 **p < .01 ***p < .001; data is effect (se) or effect (95% CI).
a-path is treatment group→ mediator, b- path is mediator→ CPD, direct effect is treatment group→ outcome, controlling for indirect effect.
Intraclass coefficients computed from intercept only models: craving (0.51); negative affect (0.61); satisfaction (0.79); reward (0.80); aversion (0.63); cigarettes per day (0.84).
Output reflects results of multi-level 1-1-1 within-person moderated mediation model with slope coefficients depicted at each level of the moderator for a-path and b-path.
Index of moderated mediation represents the difference between the indirect effect at each value of each moderator.
Each mediator was assessed in a separate model.
Bolded cells are significant below the .05 level. Italicized b-path reflects that b-path remained significant after controlling for same-day smoking.
