目的：使用多维多分类项目反应模型(MPIRM)来评估电视(TV)育儿实践(PP)工具的心理测量学特性。进行差异项目功能(DIF)分析，以检验项目参数估计是否在教育、语言或年龄组之间存在差异。方法：对德克萨斯州休斯敦358名3至12岁儿童的三项研究数据进行二次分析。电视节目计划包括15个项目，包括三个子量表：社会共同观看、指导性父母调解和限制性父母教养。使用多维部分信用模型对绩效进行评估。结果：经典测验理论分析显示出可接受的内部一致性信度(Cronbach‘sα：0.72~0.83)。在儿童年龄组中，比起父母教育或语言组，更多的项目显示出显著的DIF。Wright地图显示，项目只覆盖了分布的有限范围，在更容易回答的一端。结论：电视PP量表在父母教育、父母语言和儿童年龄的基础上发挥不同的作用，后者中DIF最高。需要更多的研究来修改量表，以最大限度地减少这些缓和的影响。有些项目可能与年龄有关。
Purposes: Use multidimensional polytomous item response modeling (MPIRM) to evaluate the psychometric properties of a television (TV) parenting practices (PP) instrument. Perform differential item functioning (DIF) analysis to test whether item parameter estimates differed across education, language, or age groups.Methods: Secondary analyses of data from three studies that included 358 children between the ages of 3 and 12 years old in Houston, Texas. TV PP included 15 items with three subscales: social co-viewing, instructive parental mediation, and restrictive parenting. The multidimensional partial credit model was used to assess the performance. DIF was used to investigate the differences in psychometric properties across subgroups.Results: Classical test theory analyses revealed acceptable internal consistency reliability (Cronbach's alpha: 0.72 to 0.83). More items displaying significant DIF were found across children's age groups than parental education or language groups. A Wright map revealed that items covered only a restricted range of the distribution, at the easier to respond end of the trait.Conclusions: TV PP scales functioned differently on the basis of parental education, parental language, and child age, with the highest DIF among the latter. Additional research is needed to modify the scales to minimize these moderating influences. Some items may be age specific.
