The objective of this study was to determine whether perceived accessibility predicted future smoking among youths. METHODS: This study used data from the second Development and Assessment of Nicotine Dependence in Youth (DANDY-2) study, a 4-year (2002-2006) cohort study that began with 1,246 sixth-grade students in 6 Massachusetts communities. DANDY-2 comprised 11 waves of in-person interviews. A total of 1,195 students who were aged 11 to 14 years at the …

Perceptions about the accessibility of cigarettes assesses availability from all potential sources and has been found to predict future smoking. This study examines the determinants of perceived accessibility from the perspective of a longitudinal study. METHODS: Data were derived from the second Development and Assessment of Nicotine Dependence in Youth study, a 4-year longitudinal study of 1246 sixth-grade students who underwent up to 11 in-person interviews from 2002 to 2006. Perceived accessibility was assessed prospectively by asking students whether they agreed …
