“…Coefficient alphas based on both samples are in bold on the diagonal. The reliability estimate for the composite performance measure is based on the formula for a stratified alpha (Rajaratnam, Cronbach, & Gleser, 1965).…”

Organizational climate as a moderator of safety knowledge–safety performance relationships

SummaryUsing training history data and supervisory ratings of 133 hazardous waste workers' safety performance collected within two organizations in the U.S. nuclear waste industry, this study examined organizational climate for the transfer of safety training as a moderator of relationships between safety knowledge and safety performance. The trend in the results was consistent with the hypothesis that these relationships would be stronger in the less restrictive (more supportive) organizational climate. The implications of these findings for promoting safe work behaviors through the creation of a positive and strategically focused organizational climate for the transfer of safety training are discussed.

“…The assumption that all items are equally discriminating may be very stringent for the entire test, but it may well fit a specific content area. This is similar to the idea of stratified coefficient alpha (Cronbach, Schoenemann, & Mckie, 1965;Rajaratnam, Cronbach, & Gleser, 1965). The original coefficient alpha (Cronbach, 1951) only holds when all items in the test are tau-equivalent.…”

Standard Error of Ability Estimates and the Classification Accuracy and Consistency of Binary Decisions

While estimation bias is a primary concern in psychological and educational measurement, the standard error is of equal importance in linking key aspects of the assessment structure, especially when the assessment goal concerns the classification of individuals into categories (e.g., master/non-mastery). In this paper, we show analytically how standard error of ability estimates affects expected classification accuracy and consistency when the decision is binary. When standard error decreases, the conditional classification accuracy and consistency increase. Given an examinee population and a cut score, smaller standard error over the entire latent trait continuum guarantees higher overall expected classification accuracy and consistency. We were also able to show the interrelationship between standard error, the expected classification consistency, and reliability. Utilizing the relationship between standard error and expected classification accuracy and consistency, we derive the upper bounds of the overall expected classification accuracy and consistency of a fixed-length computerized adaptive test. The lower bound of the expected classification accuracy and consistency is also derived given a number of stopping rules of variable-length computerized adaptive testing. Implications of these analytical results on operational tests are discussed.

“…The refinement resulted from the segmentation of factor II parallels that of going from coefficient alpha to stratified coefficient alpha (Feldt & Brennan 1989, pp. 117;Cronbach, Schonemann & McKie, 1965;Rajaratnam, Cronbach & Gleser, 1965). Similarly, model (12) is suitable for the situations as described in Li, Rosenthal and Rubin (1996) and Li (1997).…”
