Longitudinal Invariance Of The Scale Of Ethnocultural Empathy, Jerusha Joy Gerstner May 2012

Longitudinal Invariance Of The Scale Of Ethnocultural Empathy, Jerusha Joy Gerstner

Masters Theses, 2010-2019

The Scale of Ethnocultural Empathy (SEE; Wang et al., 2003) was developed to measure ethnocultural empathy and is a promising tool for assessing change in the construct over time. However, no prior study examines the functioning of the SEE over time. The purpose of the study was to examine the invariance of the SEE utilizing a modified factor model that included a negative wording effect. The SEE was found to exhibit longitudinal measurement invariance over a two-year time span in a sample of undergraduate students. Change over time was examined at the error-free, latent level and only one subscale (EPT) …


Should We Change The Way We Model Change? Comparing Traditional And Modern Techniques In Modeling Change In Sense Of Identity Over Time, Kelli Marie Samonte May 2012

Should We Change The Way We Model Change? Comparing Traditional And Modern Techniques In Modeling Change In Sense Of Identity Over Time, Kelli Marie Samonte

Masters Theses, 2010-2019

Repeated measures analysis of variance (ANOVA) and multivariate analysis of variance (MANOVA) are two of the most common techniques employed in longitudinal data analysis. These methods, however, are extremely limited in the type of data permitted in analysis, the residual covariance matrices employed in analysis, as well as in the focus of the research questions. There are, however, modern techniques for analyzing longitudinal data that do not have the same limitations of repeated measures ANOVA and MANOVA. This study aims to compare traditional methods of analyzing longitudinal data with more modern techniques, including alternative covariance structure (ACS) modeling and multilevel …
