Posterior Predictive Model Checking Of Local Misfit For Bayesian Confirmatory Factor Analysis, Chi Hang Au
Posterior Predictive Model Checking Of Local Misfit For Bayesian Confirmatory Factor Analysis, Chi Hang Au
Masters Theses, 2010-2019
Posterior predictive model checks (PPMC) are one Bayesian model-data fit approach. Thus far, PPMC for Confirmatory Factor Analytic applications focused primarily on global fit evaluation, ignoring the nuanced information in local misfit diagnostics. This study developed a PPMC approach for local misfit and applied it to a test-taking motivation scale. If the PPMC approach is effective, fit conclusions derived from the PPMC approach should be congruent with the fit conclusions derived from the Frequentist approach. Number of item-pairs flagged as misfitting and number of disagreements were computed to evaluate congruence. Congruence is achieved if the number of item-pairs flagged as …
The Effect Of Anchoring Vignettes On Factor Structures: Student Effort As An Example, Carolyn A. Miesen
The Effect Of Anchoring Vignettes On Factor Structures: Student Effort As An Example, Carolyn A. Miesen
Masters Theses, 2010-2019
Anchoring vignettes are used as a methodological technique for removing differential interpretation of response categories (DIRC) from scores on subjective self-report measures (King, Murray, Slomon, & Tandon, 2004). This technique requires participants to read one or more short scenarios, or vignettes, designed to represent various levels of a construct. Vignette ratings are used as an indication of DIRC, which is a source of differential item functioning (DIF). Prior research primarily used indirect methods for evaluating vignette quality. In response, the present set of studies proposes using invariance testing as a more direct evaluation of how the use of anchoring vignettes …
Addressing Serial-Order And Negative-Keying Effects: A Mixed-Methods Study, Jerusha J. Gerstner
Addressing Serial-Order And Negative-Keying Effects: A Mixed-Methods Study, Jerusha J. Gerstner
Dissertations, 2014-2019
Researchers have studied item serial-order effects on attitudinal instruments by considering how item-total correlations differ based on the item’s placement within a scale (e.g., Hamilton & Shuminsky, 1990). In addition, other researchers have focused on item negative-keying effects on attitudinal instruments (e.g., Marsh, 1996). Researchers consistently have found that negatively-keyed items relate to one another above and beyond their relationship to the construct intended to be measured. However, only one study (i.e., Bandalos & Coleman, 2012) investigated the combined effects of serial-order and negative-keying on attitudinal instruments. Their brief study found some improvements in fit when attitudinal items were presented …
