To identify risk and protective factors during early and later adolescence that predict future regular smoking and multiple problem behavior among at-risk youth, defined as those who tried smoking by grade 7.
At grades 7, 10, and 12, data were collected from 2,000 early smokers drawn from California and Oregon. Multivariate regression analyses tested predictors of the two grade 12 outcomes in separate models using data from grades 7 and 10. Gender interactions and buffering of risk factors by protective factors were assessed.
For at-risk youth, consistent protective factors against future smoking and problem behavior included living in an intact nuclear family (all four models) plus getting good grades and parental disapproval of smoking/drug use (three of four models). Consistent risk factors included exposure to substance-using peers (four models) and problems in school (three of four models). Adult substance use was a predictor during early, but not later, adolescence; pro-smoking/drug use beliefs were significant predictors during later adolescence. There were few differences across gender and no significant buffers against risk.
At-risk youth would likely benefit from peer resistance training, parental involvement in prevention efforts, and efforts to improve educational performance during both middle school and high school. Changing pro-drug beliefs may be more effective among older adolescents.
确定青春期早期和后期的风险因素与保护因素,这些因素可预测高危青少年(定义为在7年级前尝试吸烟的青少年)未来的经常吸烟行为和多种问题行为。
在7、10和12年级时,从加利福尼亚州和俄勒冈州抽取的2000名早期吸烟者中收集数据。多变量回归分析使用7年级和10年级的数据,在单独的模型中测试12年级两个结果的预测因素。评估了性别交互作用以及保护因素对风险因素的缓冲作用。
对于高危青少年,预防未来吸烟和问题行为的一致保护因素包括生活在完整的核心家庭(所有四个模型),以及取得好成绩和父母不赞成吸烟/吸毒(四个模型中的三个)。一致的风险因素包括接触使用物质的同龄人(四个模型)和学校问题(四个模型中的三个)。成人使用物质是青春期早期而非后期的预测因素;支持吸烟/吸毒的信念是青春期后期的重要预测因素。性别差异很少,且没有显著的风险缓冲因素。
高危青少年可能会从同伴抵制训练、父母参与预防工作以及在初中和高中期间提高学业成绩的努力中受益。改变支持吸毒的信念在年龄较大的青少年中可能更有效。
