Other studies have found that youth are far less likely to become daily smokers if neither parent smokes and if there is a smokefree policy in the home. While this study found that children of nonsmoking parents were far less likely to begin smoking, to increase smoking, and to become daily smokers (than children of smoking parents), the study's authors failed to report the results of this singularly important finding, but rather combined it with an vague classification dubbed "positive family management". The authors only cited 2 of the 14 questions used to assess "famiy management" skills, and failed to indicate if they considered (i.e. inquired about) a smokefree home policy. Perhaps the most important finding of this study (which wasn't reported in the abstract) was that the Raising Healthy Children program had very little if any impact on youth smoking behaviors, which is consistent with other studies on the impact of substance abuse prevention programs on youth.
