Child maltreatment is a complex and multifaceted construct in need of advanced statistical techniques to improve its measurement. The current study compared the predictive utility of a cumulative index to a factor analytic approach for constructing a measure of maltreatment. Data were from Waves III and IV of the National Longitudinal Study of Adolescent to Adult Health (Wave III: n = 14,800; Wave IV: n = 12,288). As adults, participants retrospectively reported on their childhood experiences of physical abuse, sexual abuse, emotional abuse, physical neglect, supervisory neglect, and social services investigations. Both the cumulative index and a two-factor solution showed evidence of convergent validity, predicting lifetime incidence of homelessness, being paid for sex, and various measures of running away or living apart from biological parents, and prospectively predicting depression, substance use, and criminal behavior. The latent variables, derived from a factor analytic approach, had greater explanatory power for many outcomes compared to the cumulative index, even when controlling for sociodemographic variables. Results suggest that factor analysis is a better methodology than a cumulative index for measuring maltreatment in large datasets when explanatory power for external outcomes is of greatest concern. 相似文献

文章基于2010—2018年中国31个省(未包括香港、澳门特别行政区和台湾地区)的面板数据进行探索性分析,并构建空间计量模型以检验公共图书馆机构数、藏书量以及人均占有量在空间分布上存在明显差异。最后,在"全民阅读"国家发展战略指导下,根据我国公共图书馆的空间分布特征,建议从四种维度创设新型公共图书馆。 相似文献

有序结构在Web2.0中有着新的表现形式,它包含了由他组织过程所生成的静态有序结构以及由自组织过程所生成的动态有序结构两种类型,这些结构的表现形式都是由其对应的控制规则所决定的。一种结构的有序程度,是以用户体验的感受程度为标准的。通过对已有的可用的有序性测度方法的比较分析,笔者指出了其各自的适应范围,并阐述了作为有序度测度发展趋势的用户体验测试方法。 相似文献

英语不定冠词在英语中使用率很高,英语名词中的可数和不可数特点使中国的英语初学者难以掌握不定冠词的用法。英语的不可数名词不能冠以不定冠词,但当不可数名词受到形容词或介词短语的修饰或限定时却变成可数名词,因而可以受到不定冠词的修饰,表示某种个别的或特殊的情况。 相似文献

Comparing self-perceived quality of teaching to students’ perception can be used in higher education to improve the quality of teaching of pre-service teachers in teacher education. However, comparing these measurements from different perspectives is only meaningful if the same constructs are being measured. To shed light on this comparison’s meaningfulness, we scrutinised whether aspects of quality of teaching are measured in the same way across pre-service teachers and their students by means of measurement invariance analyses. To do so, 272 pre-service teachers in teacher education rated aspects of their quality of teaching, and were rated by their 4851 students. Measurement invariance across these perspectives was tested in multilevel structural equation models. Strong measurement invariance held for two aspects of quality of teaching; for the third, one item lacked weak measurement invariance. Pre-service teachers perceived their quality of teaching lower than their students. In conclusion, aspects of quality of teaching can be compared across perspectives, and teacher education should encourage pre-service teachers to use students’ feedback as a valuable resource for improving their quality of teaching. 相似文献

Despite agreement about the importance of executive function (EF) for children’s early math achievement, its treatment in correlational studies reflects a lack of agreement about the theoretical connection between the two. It remains unclear whether the association between EF and math operates through a latent EF construct or specific EF components. Specifying the correct measurement model has important theoretical implications for the predicted effects of EF interventions on children’s math achievement. In the current study, we tested whether associations between EF and math operate via a latent EF factor, or via specific EF components using data from a large, nationally representative sample. We then replicated these same analyses with a meta-analytic database drawn from ten studies that collected measures of children’s EF and math achievement. Our results lend support to explanations that a single EF factor accounts for most of the EF component-specific associations with math achievement. We discuss theoretical and methodological implications of these findings for future work. 相似文献
