使用多维多分类项目反应模型评估蔬菜育儿实践量表的心理测量学特性，该模型能够评估项目与潜在变量的匹配程度以及项目与受访者的分布特征。我们还测试了儿童的性别、种族、年龄和家庭收入群体在项目功能方式(称为差异项目功能)方面的差异。3-5岁儿童的父母在网上完成了一份自我报告的蔬菜育儿实践量表。蔬菜育儿实践包括14个有效的蔬菜育儿实践和12个无效的蔬菜育儿实践项目，每个项目都有三个子量表(反应性、结构和控制)。分别对有效的蔬菜育儿行为和无效的蔬菜育儿行为进行多维多分类项目反应建模。一个有效的蔬菜育儿实践项目在全样本或跨人口群体中不适合该模型，另一个项目在不同性别的项目功能分析中不匹配。在儿童年龄和种族群体中发现了显著的项目功能差异，有效的蔬菜养育实践比无效的蔬菜养育实践项目更具差异性。赖特的地图显示，项目只覆盖了潜在特征分布的一部分。有效的蔬菜育儿做法和无效的蔬菜育儿做法分别没有涵盖结构中较难和较容易回答的末端。一些有效的蔬菜育儿实践和无效的蔬菜育儿实践量表条目因儿童的人口学特征而有不同的作用，因此，研究者在使用这些蔬菜育儿实践量表时应谨慎。项目反应模型应纳入育儿实践问卷的分析，以更好地评估不同人口统计特征的差异。
To evaluate the psychometric properties of a vegetable parenting practices scale using multidimensional polytomous item response modeling which enables assessing item fit to latent variables and the distributional characteristics of the items in comparison to the respondents. We also tested for differences in the ways item function (called differential item functioning) across child’s gender, ethnicity, age, and household income groups. Parents of 3–5 year old children completed a self-reported vegetable parenting practices scale online. Vegetable parenting practices consisted of 14 effective vegetable parenting practices and 12 ineffective vegetable parenting practices items, each with three subscales (responsiveness, structure, and control). Multidimensional polytomous item response modeling was conducted separately on effective vegetable parenting practices and ineffective vegetable parenting practices. One effective vegetable parenting practice item did not fit the model well in the full sample or across demographic groups, and another was a misfit in differential item functioning analyses across child’s gender. Significant differential item functioning was detected across children’s age and ethnicity groups, and more among effective vegetable parenting practices than ineffective vegetable parenting practices items. Wright maps showed items only covered parts of the latent trait distribution. The harder- and easier-to-respond ends of the construct were not covered by items for effective vegetable parenting practices and ineffective vegetable parenting practices, respectively. Several effective vegetable parenting practices and ineffective vegetable parenting practices scale items functioned differently on the basis of child’s demographic characteristics; therefore, researchers should use these vegetable parenting practices scales with caution. Item response modeling should be incorporated in analyses of parenting practice questionnaires to better assess differences across demographic characteristics.
