Note: For the ease of this table, responses to the single-item psychosocial mediators measures were dichotomized, where “completely disagree”, “disagree” and “neither agree nor disagree” responses were coded as “not endorsed” and “agree” and “completely agree” were coded as “endorsed”.
†
Logistic regression models were run for each mediator, where ABSTINENCE = GROUP MEDIATOR GROUP*MEDIATOR; the p-values for the GROUP*MEDIATOR term is provided here
