Psychosocial stress and impulsivity are each associated with smoking in adolescents. There is also evidence that stress can increase impulsive responding, and impulsive adolescent smokers attempting cessation are at greater risk of relapse. We performed a pilot investigation to examine stress-induced changes in response inhibition, inattention, and risk taking as related to smoking status and posttreatment smoking abstinence.
Twelve adolescent smokers participating in a smoking cessation intervention and 15 adolescent nonsmokers completed a 2-session protocol assessing stress-related change in response inhibition and inattention (on the Conners' Continuous Performance Test-II), risk taking (on the Balloon Analogue Risk Task), nicotine withdrawal symptoms, and self-reported stress.
At baseline, smokers had greater inattentive responding and risk taking when compared with nonsmokers. Stress exposure led to significant increases in stress, anger, and depression in all participants and also increased nicotine craving (on the Minnesota Nicotine Withdrawal Scale item) and impulsive responding in smokers. After covarying for baseline differences in impulsivity/risk taking, smokers who were not abstinent at the end of treatment experienced greater stress-induced risk taking when compared with those who were abstinent.
In all, it appears that response inhibition and risk taking may be differentially altered by stress exposure in adolescent smokers and nonsmokers and that adolescent smoking cessation success may be associated with less risk taking in the face of stress.
心理社会压力和冲动性与青少年吸烟有关。有证据表明,压力会增加冲动反应,而试图戒烟的冲动性青少年吸烟者复发的风险更高。我们进行了一项初步研究,以检查与吸烟状况和治疗后戒烟相关的应激诱导的反应抑制、注意力不集中和冒险行为的变化。
12 名参加戒烟干预的青少年吸烟者和 15 名青少年非吸烟者完成了一个 2 次会议的方案,评估了应激相关的反应抑制和注意力不集中(康纳斯连续性能测试 II)、冒险行为(气球模拟风险任务)、尼古丁戒断症状和自我报告的应激变化。
在基线时,吸烟者的注意力不集中和冒险行为比非吸烟者更大。在所有参与者中,应激暴露导致应激、愤怒和抑郁显著增加,并且在吸烟者中还增加了尼古丁渴望(在明尼苏达州尼古丁戒断量表项目上)和冲动反应。在对冲动性/冒险行为的基线差异进行协方差分析后,治疗结束时未戒烟的吸烟者与戒烟者相比,应激诱导的冒险行为增加。
总之,应激暴露似乎会对青少年吸烟者和非吸烟者的反应抑制和冒险行为产生不同的影响,而青少年戒烟成功可能与面对应激时的冒险行为减少有关。
