Engaging Parents Who Quit Smoking in Antismoking Socialization of Children: A Novel Approach to Relapse Prevention.

INTRODUCTION
Data from a randomized controlled trial designed primarily to test the effect of an antismoking socialization parenting program on child initiation of smoking were used to test the subsidiary hypothesis that providing antismoking socialization to children would lower the odds of relapse within a sub-sample of parents who had recently quit smoking.


METHODS
Over 13 months, 11 state Quitlines provided contact information for callers who were parents of 8- to 10-year-old children. Of 1604 parents enrolled in the trial, 689 (344 treatment; 345 control) had quit smoking cigarettes for at least 24 hours after calling a Quitline. Their data were used to test for group differences in 30-day abstinence measured using telephone interviews conducted 7 and 12 months post-baseline. Analyses of parents with complete follow-up data and intent-to-treat analyses incorporating parents lost to follow-up are presented.


RESULTS
Among 465 parents with complete follow-up data, treatment group parents had twice the odds of being abstinent 12 months post-baseline (adjusted OR = 2.01; P = .001) relative to controls. Intent-to-treat analysis with all 689 parents, in which those lost to follow-up were coded as having relapsed, showed a smaller though significant treatment effect on 30-day abstinence at 12 months (adjusted OR = 1.58; P = .017).


CONCLUSIONS
This study is the first to observe that engaging parents who have quit smoking in antismoking socialization of children can lower their odds of relapse. Additional research is needed to replicate this finding and to identify the psychological mechanisms underlying the observed effect.


IMPLICATIONS
There is a clear the need for research to develop new relapse prevention strategies. This study is the first to observe that engaging parents who have quit smoking in antismoking socialization of children can lower their odds of relapse.
