TL;DR: In view of certain psychometric deficiencies of the original psychoticism scale, an attempt was made to improve the scale by adding new items as discussed by the authors, which was attempted to increase the internal reliability of the scale, improve the shape of the distribution and increase the mean and variance score.

TL;DR: This paper argued that the chi-square exact-fit test is the only substantive test of fit for structural equation model, but, its sensitivity to discrepancies from expected values at increasing sample sizes can be highly problematic if those discrepancies are considered trivial from an explanatory-theory perspective.

TL;DR: In this paper, the means for each scale score from the Eysenck Personality Questionnaire were compared individually and conjointly across 25 countries, using coded difference scores, Pearson correlations, Euclidean distances, cluster analyses and non-metric multidimensional scaling.

TL;DR: In this article, three coefficients of factor similarity were examined with regard to their behaviour within four sets of data, and it was concluded that using the three coefficients simultaneously as a multiple indicator yielded the best solution to the problem.

TL;DR: The results demonstrate that triplefin species have diversified considerably in habitat and microposition use, resulting in species occupying different patches in the same general location and suggest that habitat use has been important in the diversification of New Zealand triplefin fishes.
