This study developed an abbreviated form of Barron's (1953) Ego Strength Scale for use in research among college student samples. A version of Barron's scale was administered to 100 undergraduate college students. Using item-total score correlations and internal consistency, the scale was reduced to 18 items (Es18). The Es18 possessed adequate…

In a Monte Carlo simulation, a methodology was developed to investigate the existence of radex properties among objective test items. In an experiment with items covering four categories of Bloom's cognitive domain taxonomy, the items did not have the factorial properties of a radex with four levels of complexity. (Author/BW)

Despite the popularity of both multiple-choice (MC) and true-false (TF) items, most investigations comparing the two formats have done so to determine the optimum number of choices to be given to students within a given time period. The purpose of this investigation was to compare the reliabilities and the validities of both formats when the items…

The Rasch model for test analysis is a latent-trait model, which specifies the relationship between observable test performance and the unobservable traits or abilities assumed under test performance. In most cases, the test constructor has no clue as to whether the latent traits postulated by the model are indeed the abilities he wants to…

A comparison is presented of alternate-choice and true-false item forms used in an undergraduate natural science course. The alternate-choice item is a modified two-choice multiple-choice item in which the two responses are included within the question stem. This study (1) compared the difficulty level, discrimination level, reliability, and…
