威斯康辛州吸烟依赖动机量表（WISDM-68）共有68个条目，是一种从理论上推导出来的烟草依赖量表，由13个测量各种吸烟动机的分量表组成。WISDM-68量表显示了良好的心理测量特征，具有阐明多种尼古丁依赖因素和机制的潜力。本研究的目的是在保持或增强其心理测量特性的同时，缩短量表的长度以减轻量表的评估负担。来自三个独立样本（一个纵向观察研究和两个随机临床试验）的数据被用来选择亚量表和减少的项目集，以开发和测试WISDM-68的简短版本。然后在三个独立样本中比较WISDM的完整项目和减少项目版本的信度，效度和模型拟合（通过验证性因子分析）。从WISDM中删除了31个条目，删除了行为选择-改善子量表，整合了负强化和正强化子量表。这产生了一个新的WISDM简短表格（简短WISDM），包括37个项目，加载到11个子量表上。在内部一致性、长期稳定性、并发效度、预测效度和模型拟合方面，减条目WISDM子量表的心理测量特性与完整条目子量表具有可比性。这些分析提供了很好的证据表明，如果研究人员希望减轻参与者的评估负担，37项简要WISDM可以取代原来的68项WISDM。
The 68-item Wisconsin Inventory of Smoking Dependence Motives (WISDM-68) is a theoretically derived measure of tobacco dependence consisting of 13 subscales measuring a variety of smoking motives. The WISDM-68 subscales have demonstrated good psychometric characteristics and have the potential to elucidate diverse nicotine dependence factors and mechanisms. The present research aimed to shorten the WISDM to reduce assessment burden while maintaining or enhancing its psychometric properties.Data from three independent samples (one longitudinal observational study and two randomized clinical trials) were used to select subscales and reduced sets of items in order to develop and test a brief version of the WISDM-68. The full-item and reduced-item versions of the WISDM were then compared in terms of reliability, validity, and model fit (via confirmatory factor analysis) in the three independent samples.Thirty-one items were dropped from the WISDM, the Behavioral Choice-Melioration subscale was dropped, and the Negative and Positive Reinforcement subscales were consolidated. This resulted in a new WISDM short form (Brief WISDM) comprising 37 items that load onto 11 subscales. The psychometric properties of the reduced-item WISDM subscales were found to be comparable with the full-item subscales in terms of internal consistency, long-term stability, concurrent validity, predictive validity, and model fit.These analyses provide good evidence that the 37-item Brief WISDM can be used in place of the original 68-item WISDM if researchers desire to reduce participant assessment burden.
