A large number of approaches have been proposed for estimating and testing the significance of indirect effects in mediation models. In this study, four sets of Monte Carlo simulations involving full latent variable structural equation models were run in order to contrast the effectiveness of the currently popular bias-corrected bootstrapping…

Extensive research has examined the effectiveness of admissions tests for use in higher education. What has gone unexamined is the extent to which tests are similarly effective for predicting performance at both the master's and doctoral levels. This study empirically synthesizes previous studies to investigate whether or not the Graduate Record…

Kaminsky and Nelson's method for estimating the times of future "success" from the times of earlier "successes" in the same sample is discussed in terms of its potential applications to long term psychological treatment, research, or training programs. (Author/JKS)

A quantitative way of measuring peer tutor training programs and peer tutor effectiveness is presented. The evaluation of a peer group training course at Baruch College (City University of New York), for which this questionnaire was developed, is described. This measure is adaptable to most higher education peer tutoring programs. (Author/BS)

This article reports a study that investigated the effects of Q-matrix misspecifications on parameter estimates and misclassification rates for the deterministic-input, noisy "and" gate (DINA) model, which is a restricted latent class model for multiple classifications of respondents that can be useful for cognitively motivated diagnostic…

Significant correlations were obtained between student ratings of the effectiveness of the guidance program and Personal Orientation Inventory scales of Time Competence and Spontaneity. Thus, the more actualizing the counselor as measured by POI, the more likely the students were to assign high ratings to the school guidance program. (Author/DEP)

A study with 206 federal government employees reveals that degree of voluntary participation in quality circles is positively related to following quality circle guidelines and that following such guidelines is positively related to economic gain. Implications of voluntary and nonvoluntary participation on cost-benefit outcomes is discussed. (SLD)
