Investigation of the 3 x 2 Achievement Goal Framework in Two University Band Contexts: Scale Development and Model Fit of a Six-Factor Structure describing University Band Students’ Goal Orientations Toward Personal and Ensemble Music Performance
… the extent to which the 3 x 2 achievement goal model fits to two contexts of university band performance. Results from a pilot study informed establishment of a 19-item 3 x 2 AGQ – MP. The resulting questionnaire featured matching items with contrasting prompts in order to measure student goal …

VALIDATING THE NURSING PRACTICE READINESS SCALE IN NEW GRADUATE NURSES IN THE UNITED STATES
… Practice Readiness Scale demonstrated poor model fit, resulting in Exploratory Factor Analysis, which led to a refined 17-item version. The revised instrument comprises three factors: Clinical Judgment and Nursing Performance, Professional Attitude, and Patient-Centeredness. A final …

The Unified Approach for Model Evaluation in Structural Equation Modeling
Practical fit indices have been widely used for model fit evaluation in Structural Equation Modeling. This dissertation discusses the properties of the fit indices including their influencing factors. These properties prevent researchers from deriving one-size-fit-all cutoffs for the fit indices. …

Validity Of The Educator Evaluation Instrument In The State Of West Virginia
… year. The data were not normal, nor was good model fit established based on the current model. Because good model fit could not be established, an exploratory factor analysis was conducted, which through principal component analysis, four components were extracted and utilized as the …

Make Some Noise: Methods for Generating Data from Imperfect Factor Models
… studies involving covariance structure models (e.g., the common factor model) have increasingly recognized the importance of incorporating error due to model misfit in simulated data. Incorporating this model error acknowledges that all models are literally false, and no covariance …

Confirmatory factor analysis of the narcissistic personality inventory (NPI) and the self-report of psychopathy scale (SRPII)
… confirmatory factor analysis (n=581). Competing models were obtained from published literature associated with each scale and also through exploratory factor analysis. From the literature, Raskin and Terry (1988) provided a seven factor NPI model, whereas Emmons (1984; 1987) suggests a four …

Evaluating Statistical Models for Baseline Characterization and Measuring Change in Environmental Monitoring Data
In Before-After monitoring studies, statistical models are used to characterize baseline (i.e., pre-disturbance) conditions, and to detect, quantify, and forecast change during operational monitoring (i.e., post-disturbance). To establish best practices for analyzing monitoring data, a model …

The application of a cognitive diagnostic model on the test of practical Chinese
Cognitive Diagnostic Models (CDMs) are frequently used in the second language proficiency exams to analyze test takers’ strengths and weaknesses. This study retrofits a CDM known as the Fusion model onto a non-diagnostic test data from the reading comprehension test of the Test of Practical Chinese …

A Psychometric Evaluation of the PBSS-20 Among Sexual and Non-sexual Minority College Students
… factor analysis was used to evaluate the model fit with this sample, invariance testing was used to compare the model among sexual and non-sexual minority students, and construct validity was evaluated. Participants included college students (<em>N</em> = 1,730; <em>M</em><sub>age</sub> = …

Antecedents to turnover intention : examining organizational learning culture and leader member exchange.
… management literature. I found an existing model of turnover intention which examined organizational learning culture, leader member exchange, and organizational commitment. The extant model had been created and previously validated with populations from Korea and Malaysia. Using path …

Investigation of Trends and Predictive Effectiveness of Crash Severity Models
… partial proportional odds (PPO) as a statistical modeling technique to compromise between ordinal and multinomial modeling techniques and to avoid violating the key assumptions in the behavior of crash severity inherent in these two alternatives. The PPO technique is compared to ordinal and …

Fast EM Based Posterior Approximation for IRT Item Parameters
… of the parameters in item response theory (IRT) models is routinely accomplished using marginalized Bayes modal estimation (MBME) as implemented through standard IRT software, such as BILOG-MG. However, checking IRT model fit is an on-going area of research, with no one method in wide use. One …

Age, Growth, and Reproduction of Vermilion Snapper (<i>Rhomboplites aurorubens</i>) in the North-Central Gulf of Mexico
… history is limited spatially. Non-linear curve fitting was used to estimate growth parameters and Akaike information criteria (AIC) was used to determine relative model fit. The 2-parameter von Bertalanffy growth function provided the best model fit and lowest AIC score. Histological examination …

An application of item response theory to language testing: Model-data fit studies
… has recently attracted much attention, no model-data fit research has been conducted to explore the appropriateness of IRT modeling in language testing. The tenability of the strong assumption of unidimensionality has not been studied systematically, and little is known concerning the …
