Previous research suggests that females may be more motivated to smoke for negative reinforcement (NR) than males. However, it remains unclear whether gender differences in smoking outcome expectancies for negative smoking reinforcement-an important theoretical and clinical target defined as beliefs that smoking alleviates negative affect-exist above and beyond gender differences in depression and/or other outcome expectancies.
Relations between gender and negative smoking reinforcement expectancies were examined in two independent samples. Sample 1 consisted of non-treatment seeking daily smokers (Male n = 188; Female n = 91) recruited from Southern California (49.5% Black, 32.2% Caucasian, and 18.3% other race/ethnicity). Sample 2 consisted of treatment seeking daily smokers (Male n = 257; Female n = 237) in Northern Florida and Vermont (10.7% Black, 82.9% Caucasian, and 6.4% other).
Females (vs. males) reported stronger NR smoking expectancies with and without statistically controlling for nicotine dependence, other smoking expectancies, and anxiety and depression in both samples (βs = .06 to .14, ps = .06 to < .001).
Beliefs that smoking alleviates negative affect may reflect a gender-specific etiological process disproportionately prominent in women. Enhancing ability to cope with negative affect without smoking or challenge NR expectancies may be particularly important for cessation treatment in women.
先前的研究表明,女性可能比男性更倾向于为了负性强化(NR)而吸烟。然而,尚不清楚在负性吸烟强化的吸烟结果预期方面的性别差异——一个重要的理论和临床目标,被定义为认为吸烟能减轻负面影响的信念——是否存在于抑郁和/或其他结果预期的性别差异之上及之外。
在两个独立样本中研究了性别与负性吸烟强化预期之间的关系。样本1由从南加州招募的不寻求治疗的每日吸烟者组成(男性n = 188;女性n = 91)(49.5%为黑人,32.2%为白种人,18.3%为其他种族/族裔)。样本2由在佛罗里达州北部和佛蒙特州寻求治疗的每日吸烟者组成(男性n = 257;女性n = 237)(10.7%为黑人,82.9%为白种人,6.4%为其他)。
在两个样本中,无论是否对尼古丁依赖、其他吸烟预期以及焦虑和抑郁进行统计学控制,女性(与男性相比)报告的负性吸烟预期都更强(β值 = 0.06至0.14,p值 = 0.06至<0.001)。
认为吸烟能减轻负面影响的信念可能反映了一种在女性中尤为突出的性别特异性病因过程。提高不吸烟应对负面影响的能力或挑战负性强化预期对于女性戒烟治疗可能尤为重要。
