Attempts to validate the Brief Wisconsin Inventory of Smoking Dependence Motives (WISDM) have produced mixed results. The objectives for the current research were to (1) evaluate the test-retest reliability, internal consistency, and concurrent validity for each of the motive scales (2) evaluate three models to determine fit based on previous research: (i) 11-factor model, (ii) 11-factor model with four error covariances specified by previous research, and (iii) 11-factor model with two higher order primary and secondary dependence motive factors, and (3) evaluate the discriminant and convergent validity of the Brief WISDM scales.
Smoking adults aged 18-65 completed a survey about their smoking behaviors and nicotine dependence with a web-based instrument that was administered at a 3-month test-retest interval. Psychometric properties and test-retest reliability were evaluated for each instrument. The 11-factor Brief WISDM was evaluated with confirmatory factor analyses; the scales were evaluated for convergent and discriminant validity.
The Brief WISDM demonstrated good to excellent test-retest reliability. Confirmatory factor analysis showed the model with the second order primary and secondary dependence motive factors demonstrated the best fit for the data at both administrations. Discriminant validity issues were present for most of the primary dependence motive scales.
To date, the theoretically derived smoking motives for the Brief WISDM have demonstrated mixed support when submitted to confirmatory factor analysis. While these scales tap critical motives of nicotine dependence, further refinement of primary dependence motives is necessary to ensure each latent variable assesses a unique construct.
验证《威斯康星吸烟依赖动机简表》（WISDM）的尝试产生了喜忧参半的结果。本研究的目的是：（1）评估每个动机量表的重测信度、内部一致性和同时效度；（2）根据先前研究评估三种模型以确定拟合度：（i）11因素模型，（ii）具有先前研究指定的四个误差协方差的11因素模型，以及（iii）具有两个高阶主要和次要依赖动机因素的11因素模型；（3）评估简版WISDM量表的区分效度和聚合效度。
18至65岁的吸烟成年人通过基于网络的工具完成了一项关于其吸烟行为和尼古丁依赖的调查，该工具以3个月的重测间隔进行施测。对每个工具的心理测量特性和重测信度进行了评估。使用验证性因素分析对11因素简版WISDM进行评估；对量表的聚合效度和区分效度进行了评估。
简版WISDM表现出良好至优秀的重测信度。验证性因素分析表明，具有二阶主要和次要依赖动机因素的模型在两次施测中对数据的拟合度最佳。大多数主要依赖动机量表存在区分效度问题。
迄今为止，简版WISDM从理论上推导出来的吸烟动机在进行验证性因素分析时得到的支持喜忧参半。虽然这些量表挖掘了尼古丁依赖的关键动机，但有必要进一步完善主要依赖动机，以确保每个潜在变量评估一个独特的结构。
