简介：怀孕期间吸烟对胎儿和婴儿的发育构成已知的风险。怀孕期间继续吸烟的妇女比戒烟的妇女表现出更高的尼古丁依赖性。增加对怀孕吸烟者尼古丁依赖结构的了解可能有助于开发有效的治疗方法。研究表明，尼古丁依赖是一个多方面的结构，不仅受戒断和耐受过程的驱动，还受强化，感觉和上下文过程的驱动。吸烟依赖动机（WISDM-68）的威斯康星州库存评估13个不同的吸烟动机，以评估过程中，可能导致尼古丁dependence.Methods：的因素结构的WISDM-68探讨了使用种族多样性的294名孕妇谁已被筛选和/或参加了戒烟治疗研究。用先前发表的模型进行了验证性分析。探索性因素分析和探索性结构方程模型（ESEM）进行开发和验证测量模型的WISDM-68在这个sample.Results：以前建立的模型是不是一个很好的适合目前的数据。使用环境扫描电镜，一个9因素模型，表现出预测和并发效度出现。两个因素预测戒烟6个月后治疗。有几个因素与吸烟的沉重，Fagerstrom测试香烟依赖性和时间第一cigaretts.Conclusions：在以前发表的研究相比，一个9因素模型最好的特点WISDM在本样本。这些发现可能反映了年轻孕妇在怀孕期间继续吸烟的独特吸烟动机。
Introduction: Smoking during pregnancy poses known risks to fetal and infant development. Women who continue to smoke during pregnancy exhibit higher levels of nicotine dependence than women who quit. Increased understanding of the construct of nicotine dependence in pregnant smokers may aid in the development of effective treatments. Research has suggested that nicotine dependence is a multifaceted construct, driven not only by withdrawal and tolerance processes, but also by reinforcement, sensory, and contextual processes. The Wisconsin inventory of smoking dependence motives (WISDM-68) assesses 13 varied smoking motives in order to assess processes that may lead to nicotine dependence.Methods: The factor structure of the WISDM-68 was explored using an ethnically diverse sample of 294 pregnant women who had been screened and/or enrolled in a smoking cessation treatment study. Confirmatory analyses were conducted with previously published models. An exploratory factor analysis and exploratory structural equation modeling (ESEM) were conducted to develop and validate a measurement model for the WISDM-68 in this sample.Results: Previously established models were not a good fit for the present data. Using ESEM, a 9-factor model exhibiting both predictive and concurrent validity emerged. Two factors predicted abstinence 6 months posttreatment. Several factors were associated with smoking heaviness, the Fagerstrom test for cigarette dependence and time to first cigarette.Conclusions: In contrast to previously published studies, a 9-factor model best characterizes the WISDM in the present sample. These findings may reflect smoking motivations unique to young, pregnant women who continue to smoke during pregnancy.
