简介：尽管每天吸烟较少，但与白人吸烟者相比，非裔美国人吸烟者戒烟更困难。进一步阐明吸烟动机对吸烟行为的影响将有助于了解保持smoking.Aims的因素：本研究探讨了一个简短的评估因素结构，检查吸烟依赖的动机之间的一个样本的非裔美国人的轻smoking.Methods：数据从一个双盲，安慰剂对照的随机戒烟试验，涉及540名参与者。结果进行了分析，使用探索性因素分析（EFA）和随机分裂EFA.Results/调查结果：调查结果从最初的EFA分析产生了一个八因素模型，解释了69%的反应的变化。总体抽样准确度（MSA）为0.88，30个项目的项目水平MSA范围为0.68-0.94。随机分割的EFA的结果复制了原始EFA的发现;除了项目“我在早上醒来的前30分钟内吸烟”。这些发现支持了尼古丁依赖概念化的多维方法的假设，并提供有关非裔美国人轻度吸烟者尼古丁依赖特征的信息，这可能有助于确定在这一人群中戒烟。
Introduction: Despite smoking fewer cigarettes per day, African American smokers have greater difficulty quitting compared to Caucasian smokers. Further elucidating the impact of smoking motivations on smoking behaviour would contribute to understanding the factors that maintain smoking.Aims: This study examined the factor structure of a brief assessment examining smoking dependence motives among a sample of African American light smokers.Methods: Data from a double-blind, placebo-controlled randomised smoking cessation trial involving 540 participants. Results were analysed using an exploratory factor analysis (EFA) and a randomly split EFA.Results/Findings: Findings from the initial EFA analysis produced an eight-factor model, explaining 69% of the variation in responses. The overall Measure of Sampling Adequacy (MSA) was 0.88 with item level MSA ranging 0.68-0.94 across the 30 items. Results from the randomly split EFA replicated the findings of the original EFA; with the exception of the item 'I smoke within the first 30 minutes of awakening in the morning'.Conclusions: These findings support the hypothesis of a multidimensional approach to conceptualising nicotine dependence, and provide information regarding characteristics of nicotine dependence in African American light smokers which may be helpful in identifying targets for cessation treatment in this population of smokers.
