Background

Despite copious information on the hazards of nicotine and cannabis, many adolescents report vaping nicotine and cannabis. To advance knowledge on the precursors of vaping behaviors, this study examined the association of behavioral inhibition system (BIS) and behavioral activation system (BAS) sensitivities with nicotine and cannabis vaping among adolescents.

Methods

Data were part of a longitudinal survey on substance use and mental health among adolescents and included 2,467 11th grade students from 10 public high schools in California. Participants completed a 20-item scale assessing BIS (one aspect) and BAS (three aspects: drive, fun-seeking, reward responsiveness) sensitivities at baseline and reported their past 30-day nicotine and cannabis vaping at baseline and again at 6-month follow-up. Unadjusted and adjusted (controlled for demographic characteristics and product-specific baseline vaping) regression models estimated vaping risk at follow-up by BIS/BAS scores at baseline.

Results

Bivariate analyses showed participants who vaped nicotine had significantly higher drive and fun-seeking scores (p < 0.05); and cannabis vapers had lower BIS and reward responsiveness scores (p < 0.05) compared to non-users. Higher fun seeking scores was associated with increased odds (OR = 1.15, 95 %CI = 1.03–1.29) of nicotine vaping and higher reward responsiveness scores reduced odds (OR = 0.89, 95 %CI = 0.79–0.99) of nicotine vaping. Higher scores on BIS was associated with decreased the odds (OR = 0.91, 95 %CI = 0.84–0.99) of cannabis vaping.

Conclusion

Different behavioral motivations should be targeted when developing interventions designed to reduce nicotine and cannabis vaping among diverse adolescents.

Vaping 动机：行为抑制和行为激活系统与青少年吸食尼古丁和大麻的关联

背景

尽管有大量关于尼古丁和大麻危害的信息，但许多青少年报告吸食尼古丁和大麻电子烟。为了推进对电子烟行为前兆的了解，本研究调查了行为抑制系统 (BIS) 和行为激活系统 (BAS) 敏感性与青少年吸食尼古丁和大麻电子烟之间的关联。

方法

数据是关于青少年药物使用和心理健康的纵向调查的一部分，包括来自加利福尼亚州 10 所公立高中的 2,467 名 11 年级学生。参与者完成了一个包含 20 个项目的量表，评估基线时的 BIS（一个方面）和 BAS（三个方面：驱动、寻求乐趣、奖赏反应）敏感性，并报告他们过去 30 天在基线和 6 个月时吸食尼古丁和大麻的情况跟进。未调整和调整（针对人口统计特征和产品特定基线吸电子烟进行控制）回归模型根据基线时的 BIS/BAS 分数估计后续的吸电子烟风险。

结果

双变量分析显示吸食尼古丁的参与者有更高的动力和寻求乐趣的分数（p < 0.05）；与非吸食者相比，大麻吸食者的 BIS 和奖赏反应得分较低 (p < 0.05)。较高的寻求乐趣分数与尼古丁电子烟的几率增加 (OR = 1.15, 95 %CI = 1.03–1.29) 相关，而较高的奖赏反应分数与尼古丁电子烟的几率降低 (OR = 0.89, 95%CI = 0.79–0.99) 相关。BIS 得分较高与吸食大麻的几率降低相关（OR = 0.91，95%CI = 0.84–0.99）。

结论

在制定旨在减少不同青少年吸食尼古丁和大麻电子烟的干预措施时，应针对不同的行为动机。
