BACKGROUND No long-term impact has yet been observed with the use of the social-influences approach to school-based smoking prevention for youth. However, whether this lack of impact is due to methodologic problems with the studies or to the failure of the interventions is unclear. The Hutchinson Smoking Prevention Project (HSPP), conducted from September(More)
AIMS The first prospective investigation of the extent to which parental smoking cessation predicts their children's daily smoking. DESIGN Parental smoking status was assessed when children were aged 8/9 years and children's smoking status was assessed at age 17/18 years. SETTING Twenty Washington State school districts in the control group of the(More)
Two popular censored data rank tests were used to compare cancer incidence rates between dogs receiving bone marrow transplantation and control dogs. The logrank test gave a significance level of 0.01. In contrast, Gehan's generalized Wilcoxon test gave a significance level of 0.76. The statistics are displayed in a manner that shows how such contrasting(More)
For scientific and public health reasons, it is important to identify the role of family influences on child smoking acquisition. Using a well-followed (>90%) cohort of 3,012 children and their parents, this study prospectively investigated the influence of smoking by 0 vs. 1 vs. 2 parents when the children were young (3rd grade), on whether the children(More)
BACKGROUND The effects of mothers' attitudes and concerns about tobacco use on whether their children take up smoking are largely unknown. This study examined the predictive effects of mothers' attitudes about tobacco and concerns about their children smoking. METHODS Self-reported data from a large number of 12th-grade students (2,736) and their mothers(More)
BACKGROUND The Hutchinson Study of High School Smoking randomized trial was designed to rigorously evaluate a proactive, personalized telephone counseling intervention for adolescent smoking cessation. METHODS Fifty randomly selected Washington State high schools were randomized to the experimental or control condition. High school junior smokers were(More)
Only one prior study has examined why adolescent smoking cessation interventions are effective. To address this understudied and important issue, we examined whether a large adolescent smoking cessation intervention trial's outcomes were mediated by social cognitive theory processes. In a randomized trial (N = 2,151), counselors proactively delivered a(More)
Nonadherence to accepted design principles for randomized trials has been a limitation of school-based intervention research. Designed to overcome these limitations, the Hutchinson Smoking Prevention Project (HSPP) is a 15-year randomized trial to determine the extent to which a school-based (grades 3-12) tobacco use prevention intervention can deter youth(More)
Participant recruitment and retention have been identified as challenging aspects of adolescent smoking cessation interventions. Problems associated with low recruitment and retention include identifying smokers, obtaining active parental consent, protecting participants' privacy, respecting participants' autonomy, and making participation relevant and(More)
BACKGROUND Quitline smoking cessation counseling results in a mere 12% success rate. Testing of new telephone-delivered cessation counseling approaches is needed. OBJECTIVE Determine the feasibility of the first telephone-delivered Acceptance and Commitment Therapy (ACT) intervention for smoking cessation. DESIGN Fourteen adults (57% racial/ethnic(More)
