Research indicates that negative affect and/or depression is associated with increased prevalence for smoking and higher levels of nicotine dependence in adults and adolescents. A previous study with adult smokers attempting to quit indicated that low levels of self-efficacy partially mediated depression's adverse effect on posttreatment cessation.
The current study attempted to test self-efficacy as a potential mediator between depressive symptoms and smoking susceptibility in adolescents. One thousand and ninety-three nonsmoking high-school students who were part of a large clinical trial evaluating an interactive CD-ROM-based smoking prevention/cessation curriculum (project ASPIRE) were included in this analysis. These students completed an extensive battery before treatment and 18 months after treatment, which included measures of depression, self-efficacy, smoking status, and smoking susceptibility.
Results indicated that self-efficacy partially mediated the positive relationship between baseline depressive symptoms and susceptibility to smoke at 18 months, accounting for approximately 27% of the variance.
Perhaps future interventions to prevent smoking in adolescents can target self-efficacy potentially resulting in more effective outcomes, particularly in adolescents with current depressive symptoms or who may be at risk for future depression.
研究表明，消极情绪和/或抑郁与成年人和青少年吸烟率增加和尼古丁依赖程度更高有关。一项针对试图戒烟的成年吸烟者的先前研究表明，自我效能感水平较低部分中介了抑郁对治疗后戒烟的不利影响。
本研究试图检验自我效能感是否是青少年抑郁症状与吸烟易感性之间的潜在中介因素。共有 1093 名不吸烟的高中生参与了一项大型临床试验，该试验评估了一种基于交互式 CD-ROM 的吸烟预防/戒烟课程（ASPIRE 项目），他们在治疗前和治疗后 18 个月完成了一系列广泛的测试，包括抑郁、自我效能、吸烟状况和吸烟易感性的测量。
结果表明，自我效能感部分中介了基线抑郁症状与 18 个月时吸烟易感性之间的正相关关系，解释了大约 27%的变异。
也许未来预防青少年吸烟的干预措施可以针对自我效能感，从而获得更有效的结果，特别是针对当前有抑郁症状或可能有未来抑郁风险的青少年。
