This article compares a variety of imputation strategies for ordinal missing data on Likert scale variables (number of categories = 2, 3, 5, or 7) in recovering reliability coefficients, mean scale scores, and regression coefficients of predicting one scale score from another. The examined strategies include imputing using normal data models with naïve rounding/without rounding, using latent variable models, and using categorical data models such as discriminant analysis and binary logistic regression (for dichotomous data only), multinomial and proportional odds logistic regression (for polytomous data only). The result suggests that both the normal model approach without rounding and the latent variable model approach perform well for either dichotomous or polytomous data regardless of sample size, missing data proportion, and asymmetry of item distributions. The discriminant analysis approach also performs well for dichotomous data. Naïvely rounding normal imputations or using logistic regression models to impute ordinal data are not recommended as they can potentially lead to substantial bias in all or some of the parameters. 相似文献

This study has established a relationship model encompassing such aspects as consumer values, consumer involvement, purchase behavior, and consumer satisfaction. Furthermore, taking counterfeit goods as an example, this study employs factor analysis, reliability analysis, and the structural equation model to verify the relationship between the research aspects. Another major discovery of this study was that teenagers' behavioral purchasing mentality is graphic, hyperlinked, and is geared toward useful situations and functional needs. When they consider their degree of need, they inevitably incorporate many emotional needs. However, their attitude toward counterfeit goods is rational, which is confirmed by the fact that Hypothesis 1 was not supported. 相似文献

Engagement in behavioral parent training programs continues to be a barrier to service delivery. Parental readiness is an important construct for understanding parental engagement in parent training services, as these programs place a high level of action-oriented demands on caregivers. The present study examines the performance of one parental readiness measure, the Readiness, Efficacy, Attributions, Defensiveness, and Importance Scale—Short Form (READI-SF) in a community-based sample. Participants included 103 families of children ages three to seven recruited from an urban charter school. Mothers completed an abbreviated version of the READI as well as indices of child disruptive behavior and a second measure of parental readiness. The psychometric properties and factor structure of the READI-SF are explored as well as indices of reliability and validity. Exploratory factor analysis revealed a three-factor model of readiness to change, treatment readiness, and perceived importance of the problem. Analyses also supported the validity and clinical utility of the measure, as READI-SF scores were found to predict attendance at a one-time parenting group. Lastly, the study examines the relationship between parental readiness and child disruptive behavior. Limitations and future directions are discussed. 相似文献

采用现场研究的方法,对来自16个组织的1195名参加应聘的应聘者与招募者之间进行互动评价。结果验证了招募者对应聘者内隐匹配评价的二阶四维度模型,同时还验证了ASD成长模型的"A"阶段的作用机制,即在现实人事选拔过程中,招募者匹配评价和胜任力评价对雇佣推荐都有显著作用,且P-J匹配评价和基本管理特质的影响效果要大于其他。 相似文献

因子的确证问题关系到因子分析中保留几个因子,甚至关系到心理测量学的未来发展。历史上曾出现过三种取向:数理取向、哲理取向和心理取向。数理取向认为因子的确证应在与别的因子的数理关系中进行;哲理取向认为因子的确证应在逻辑关系中进行的;心理取向则认为因子的确证需要有心理基础。对于心理取向的漠视阻碍了研究者对因子实质的深入思考,造成研究难以深入,研究未整合等诸多问题。整合三种取向有利于建立正确的因子分析的研究观念。 相似文献

信息显示板(IDB)实验在消费行为研究中的应用 总被引:2,自引:0,他引:2
信息显示板(Information Display Board, IDB)实验是一种过程跟踪技术,以m×n矩阵方式呈现信息阵列,通过观测被试信息检索和浏览的一系列行为,来研究被试问题解决和决策中的信息获得(information acquisition)过程。Mouselab是常用的IDB计算机化程序。消费者是有限理性的问题解决者,因此IDB实验被用于消费行为领域的研究。应用不同的IDB实验设置,研究者探索了消费决策中消费者信息获得的模式和影响因素。 相似文献
