Comparative fit indexes in structural models
TLDR
A new coefficient is proposed to summarize the relative reduction in the noncentrality parameters of two nested models and two estimators of the coefficient yield new normed (CFI) and nonnormed (FI) fit indexes.Abstract:
Normed and nonnormed fit indexes are frequently used as adjuncts to chi-square statistics for evaluating the fit of a structural model A drawback of existing indexes is that they estimate no known population parameters A new coefficient is proposed to summarize the relative reduction in the noncentrality parameters of two nested models Two estimators of the coefficient yield new normed (CFI) and nonnormed (FI) fit indexes CFI avoids the underestimation of fit often noted in small samples for Bentler and Bonett's (1980) normed fit index (NFI) FI is a linear function of Bentler and Bonett's non-normed fit index (NNFI) that avoids the extreme underestimation and overestimation often found in NNFI Asymptotically, CFI, FI, NFI, and a new index developed by Bollen are equivalent measures of comparative fit, whereas NNFI measures relative fit by comparing noncentrality per degree of freedom All of the indexes are generalized to permit use of Wald and Lagrange multiplier statistics An example illustrates the behavior of these indexes under conditions of correct specification and misspecification The new fit indexes perform very well at all sample sizesread more

Racial Battle Fatigue and the MisEducation of Black Men: Racial Microaggressions, Societal Problems, and Environmental Stress
TL;DR: This article examined the experiences of 661 Black men and found that as educational attainment increases toward college completion, both racial microaggressions and societal problems contribute to more than one third of the cause of MEES.

Toward a better understanding of psychological contract breach: a study of customer service employees.
TL;DR: The research found that psychological contract breach was related to lower organizational trust, which was associated with perceptions of less cooperative employment relations and higher levels of absenteeism, and perceptions of external market pressures moderated the effect of psychological contract Breach on absenteeism.

Parent and teacher ratings of attention-deficit/hyperactivity disorder symptoms: Factor structure and normative data.
George J. DuPaul,Robert Reid,Arthur D. Anastopoulos,Matthew C. Lambert,Marley W. Watkins,Thomas J. Power +5 more
TL;DR: The fit of a correlated, 2-factor structure of ADHD was examined and was confirmed for both parent and teacher ratings and was invariant across child gender, age, informant, informant gender, and language.

From Passive to Proactive Motivation: The Importance of Flexible Role Orientations and Role Breadth Self-efficacy
TL;DR: In this article, two potentially important precursors to proactive workforce are shown to have construct validity and to be distinct from related dispositional variables, but their discriminant validity in terms of outcome variables has not been demonstrated.

Significance tests and goodness of fit in the analysis of covariance structures
TL;DR: In this article, a general null model based on modified independence among variables is proposed to provide an additional reference point for the statistical and scientific evaluation of covariance structure models, and the importance of supplementing statistical evaluation with incremental fit indices associated with the comparison of hierarchical models.

A reliability coefficient for maximum likelihood factor analysis
Ledyard R Tucker,Charles Lewis +1 more
TL;DR: In this paper, a reliability coefficient is proposed to indicate quality of representation of interrelations among attributes in a battery by a maximum likelihood factor analysis, which can indicate that an otherwise acceptable factor model does not exactly represent the interrelations between the attributes for a population.

Model Selection and Akaike's Information Criterion (AIC): The General Theory and Its Analytical Extensions.
TL;DR: In this article, the entropy-based information criterion (AIC) has been extended in two ways without violating Akaike's main principles: CAIC and CAICF, which make AIC asymptotically consistent and penalize overparameterization more stringently.

Goodness-of-fit indexes in confirmatory factor analysis : The effect of sample size
TL;DR: In this paper, the influence of sample size on different goodness-of-fit indices used in confirmatory factor analysis (CFA) was examined and the results are consistent with the observation that the amount of random, unexplained variance varies inversely with sample size.
