Note:
Separate models was run for each predictor. The main effect model for baseline covariates and AIS without predictors is shown.
The effect of the level 1 predictor on abstinence when pre-quit experiential avoidance is at its overall mean (pre-quit AIS mean = 42.91).
Interaction terms evaluated in a subsequent model for each predictor variable. All other terms are derived from the main effects models. Intercept was specified as random and all other predictors were treated as fixed. FTND: Fagerstrom Test for Nicotine Dependence; CES-D: Center for Epidemiological Studies-Depression scale; AIS: Avoidance and Inflexibility Scale. All within-subject predictors and moderators were assessed at the same as smoking status.
