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

The construct validity of an alternative measure of burnout: Investigating the English translation of the Oldenburg Burnout Inventory
TL;DR: In this article, the authors developed evidence for the validity and reliability of an English-language translation of the Oldenburg Burnout Inventory (OLBI) and assessed the characteristics of the OLBI using data from 2599 employees across two samples from the United States.

Perceived security and World Wide Web purchase intention
TL;DR: The creation of a scale to measure perceived Web security is described and the favorable psychometric properties of the scale are indicated, and the causal analysis indicates that security is a greater influence on intent to purchase using the Web than is the ease and utility of purchasing products.

Self-concordance, goal attainment, and the pursuit of happiness : Can there be an upward spiral?
TL;DR: The self-concordance model of healthy goal striving was used to examine the motivational processes by which people can increase their level of well-being during a period of time and then maintain the gain or perhaps increase it even further during the next period oftime.

Interactivity and vividness effects on social presence and involvement with a web-based advertisement
TL;DR: In this paper, the effects of various levels of interactivity and vividness of a message on attitudes and behavioral intentions within a web-based advertisement were measured by means of individual analysis of covariance procedures.

Religion's role in adjustment to a negative life event: coping with the loss of a child.
TL;DR: Religious participation and importance were indirectly related to greater well-being and less distress among parents 18 months after their infants' deaths and suggest that further study of the social and cognitive aspects of religion would be profitable.

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.
