Readiness to change smoking behavior in adolescents with psychiatric disorders.

There has been recent increased interest in utilizing motivational interviewing (MI) to increase adolescent readiness to quit smoking, but attempts to impact quit rates have thus far been discouraging. A better understanding of factors associated with adolescent readiness to quit smoking prior to receiving any intervention may provide guidance when tailoring future MI interventions in order to increase their effectiveness with this population. Adolescent smokers (N=191) who had been admitted to a psychiatric hospital and enrolled in a clinical trial evaluating MI completed questionnaires that assessed smoking behavior and variables thought to be related to smoking. Confidence to quit smoking and negative beliefs about smoking were significant predictors of adolescents' baseline readiness to quit smoking. The failure to demonstrate relationships between health consequences and readiness suggest that caution may be warranted in the use of feedback, a common component of MI-based interventions. Such feedback tends to focus on health consequences, which was unrelated to adolescent baseline readiness to change smoking behavior in the current study. Parallels between current results and the Theory of Planned Behavior are discussed in consideration of developing more effective MI-based interventions for adolescent smokers.
