Jangle Fallacy: Is Grit Distinct From Other Psychological Constructs?, Natasha Godkin
Jangle Fallacy: Is Grit Distinct From Other Psychological Constructs?, Natasha Godkin
Electronic Theses and Dissertations
This paper assessed the redundancy of the construct of grit (Crede, Tynan, Harms, 2017) compared to other similar constructs using structural equation modeling to remove the effect of measurement error. A series of models regressed grit and its subdomains (passion and perseverance of effort) on self-control, conscientiousness, achievement striving, and resilience. The R-squared values for these models ranged from 0.62 to 0.89. It is concluded that the concept of grit is mostly redundant with other constructs and is therefore an example of a Jangle fallacy (Kelley, 1927). The unique aspect of grit is mostly related to its passion …
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 …
Internal Consistency Of The Self-Perception Profile For Children: Using Covariance Structure Modeling To Overcome The Limitations Of Cronbach's Α, Ian Cero
All Graduate Theses, Dissertations, and Other Capstone Projects
Self-perception is linked to a variety of psychosocial outcomes and its measurement has become a priority across a several disciplines. The Self-Perception Profile for Children (SPP-C) is commonly utilized to measure both global self worth and several important sub-domains of self-perception. Although much research has suggested this instrument possesses good internal consistency, previous investigations have primarily employed Cronbach's α; to estimate the stability of responding across items. This represents an important limitation, as α; is vulnerable to mis-estimation in the presence of correlated errors and non-τ-equivalent indicators, neither of which have been ruled out for the SPP-C. The present investigation …
Methods Of Detecting Differential Item Functioning: A Comparison Of Confirmatory Factor Analysis Methods, Jenny Chia Yi Kuang
Methods Of Detecting Differential Item Functioning: A Comparison Of Confirmatory Factor Analysis Methods, Jenny Chia Yi Kuang
Psychology Theses & Dissertations
The present Monte Carlo study compared four confirmatory factor analysis (CFA) methods for detecting differential item functioning (DIF). The four methods were the noniterative and iterative mean and covariance structure analysis (MACS) methods, the modification index (MI) method, and the modification index-divided sample (MI-divided) method. Reference and focal groups responded to 12 items with 3 of the 12 items designed to exhibit DIF. Sample sizes of 250 and 500 were examined. In addition, three types of DIF were examined: DIF on loadings, DIF on thresholds, and DIF on both loadings and thresholds. Results indicated that for sample size 250, all …
