Adolescent reasons for quitting smoking: initial psychometric evaluation.

Most adolescent smokers report intentions to quit, and the majority attempt cessation. However, little is known regarding the relationship between adolescent motives for cessation and smoking cessation efforts. To this end, the present study describes an initial evaluation of the psychometric characteristics of the Adolescent Reasons for Quitting scale (ARFQ), a measure of adolescent motives for smoking cessation. Participants were 109 current smoking high school students assessed at baseline and 6-month follow-up. The ARFQ item content and format was developed in a separate qualitative study with 36 high school students who had previously attempted to quit smoking. Exploratory factor analyses of ARFQ items yielded 3 subscales: Short-Term Consequences, Social Disapproval, and Long-Term Concerns. Validation analyses were conducted in relation to concurrent intentions to stop smoking and prospective smoking cessation attempts, providing evidence of concurrent, predictive, and discriminant validity. In particular, the Social Disapproval and Long-Term Concerns subscales significantly predicted subsequent cessation attempts. As such, the ARFQ may prove valuable for informing interventions to encourage adolescent smoking cessation.
