The present study extended the results of previous research in applying the "stages of acquisition" model to the onset of smokeless tobacco as well as cigarette use. Three expert judges classified an initial pool of items as to whether they represented "precontemplation," "contemplation," "action," or "maintenance" stages of smokeless tobacco acquisition. Fifty items with adequate inter-rater reliability were combined with 21 previously developed items pertaining to cigarette smoking acquisition in an overall tobacco acquisition questionnaire, which in turn was administered to 358 junior and senior high public school students. Three distinct components labeled precontemplation, action, and maintenance were delineated through principal component analyses. Coefficient alphas and discriminant analyses according to self-reported use demonstrated adequate reliability and validity for the new smokeless tobacco- and previously developed smoking-acquisition scale.
本研究扩展了先前研究的结果，将“获取阶段”模型应用于无烟烟草以及香烟使用的起始阶段。三位专家评委将最初的一组项目分类，判断它们是否代表无烟烟草获取的“未考虑阶段”“考虑阶段”“行动阶段”或“维持阶段”。在一份总体烟草获取问卷中，将50个具有足够评分者间信度的项目与先前开发的21个与吸烟获取相关的项目相结合，该问卷随后被发放给358名初中和高中公立学校学生。通过主成分分析划分出了三个不同的成分，分别标记为未考虑阶段、行动阶段和维持阶段。根据自我报告的使用情况进行的系数阿尔法分析和判别分析表明，新的无烟烟草获取量表以及先前开发的吸烟获取量表具有足够的信度和效度。
