Notes. Standardized estimates are shown (i.e., using rescaled mediators). “a path” = effect of treatment on mediator; “b path” = effect of mediator on abstinence, controlling for treatment; “indirect effect” = indirect effect of treatment on abstinence through mediator; “direct effect” = effect of treatment on abstinence, controlling for mediator. Mindfulness-Based Addiction Treatment (MBAT) coded as 1, Usual Care (UC) as 0. Models controlled for demographics and baseline smoking. Variables in bold represent significant indirect effects based on alpha = .05.
