Skidmore, Susan Troncoso; Thompson, Bruce – Educational Researcher, 2012
In this article, the authors examine the interconnections among education researchers' misconceptions about the quality of the education research literature. Specifically, the authors catalog the sequence of events that, when taken together with a series of contradictory graphs presented by influential scholars in prominent settings, may have…

Zientek, Linda Reichwein; Thompson, Bruce – Research in the Schools, 2010
Self-efficacy and mathematics anxiety have been identified as predictors of mathematics achievement. In the present study, secondary analyses on matrix summaries available from prior published studies were utilized to investigate the contribution that self-efficacy and mathematics anxiety made in mathematics performance. Commonality analyses were…

Wang, Zhongmiao; Thompson, Bruce – Journal of Experimental Education, 2007
In this study the authors investigated the use of 5 (i.e., Claudy, Ezekiel, Olkin-Pratt, Pratt, and Smith) R[squared] correction formulas with the Pearson r[squared]. The authors estimated adjustment bias and precision under 6 x 3 x 6 conditions (i.e., population [rho] values of 0.0, 0.1, 0.3, 0.5, 0.7, and 0.9; population shapes normal, skewness…

Thompson, Bruce; Cook, Colleen; Kyrillidou, Martha – portal: Libraries and the Academy, 2006
The LibQUAL+[TM] protocol solicits open-ended comments from users with regard to library service quality, gathers data on 22 core items, and, at the option of individual libraries, also garners ratings on five items drawn from a pool of more than 100 choices selected by libraries. In this article, the relationship of scores on these locally…

Thompson, Bruce – Counseling and Values, 2006
Effect sizes (e.g., Cohen's d, Glass's [delta], [[eta] [squared]], adjusted [R [squared]], [[omega] [squared]]) quantify the extent to which sample results diverge from the expectations specified in the null hypothesis. The present article addresses 5 related questions, First, is the advocacy for reporting and interpreting effect sizes part of the…

Wei, Youhua; Thompson, Bruce; Cook, C. Colleen – portal: Libraries and the Academy, 2005
LibQUAL+[TM] data to date have not been subjected to the modern measurement theory called polytomous item response theory (IRT). The data interpreted here were collected from 42,090 participants who completed the "American English" version of the 22 core LibQUAL+[TM] items, and 12,552 participants from Australia and Europe who…

Courville, Troy; Thompson, Bruce – Educational and Psychological Measurement, 2001
Reviewed articles published in the "Journal of Applied Psychology" (JAP) to determine how interpretations might have differed if standardized regression coefficients and structure coefficients (or bivariate "r"s of predictors with the criterion) had been interpreted. Summarizes some dramatic misinterpretations or incomplete…

Kieffer, Kevin M.; Reese, Robert J.; Thompson, Bruce – Journal of Experimental Education, 2001
Investigated the patterns of statistical usage and reporting in 756 articles published in the "American Educational Research Journal" (AERJ) and the "Journal of Counseling Psychology" (JCP) over 10 years. Evaluated the analytic practices used. Also discusses changes that may be necessary to improve statistics in behavioral…

Vacha-Haase, Tammi; Kogan, Lori R.; Thompson, Bruce – Educational and Psychological Measurement, 2000
Investigated how dissimilar in composition and variability samples inducting reliability coefficients from prior studies were from the cited prior samples from which coefficients were generalized. Results from 20 articles show that citing reliability coefficients from prior studies as the basis for concluding new scores are reliable is only…

Thompson, Bruce; Crowley, Susan – 1994
Most training programs in education and psychology focus on classical test theory techniques for assessing score dependability. This paper discusses generalizability theory and explores its concepts using a small heuristic data set. Generalizability theory subsumes and extends classical test score theory. It is able to estimate the magnitude of…

Thompson, Bruce; Snyder, Patricia A. – Journal of Counseling & Development, 1998
Investigates two aspects of research analyses in quantitative research studies reported in the 1996 issues of "Journal of Counseling & Development" (JCD). Acceptable methodological practice regarding significance testing and evaluation of score reliability has evolved considerably. Contemporary thinking on these issues is described; practice as…

Thompson, Bruce – 1996
A general linear model (GLM) framework is used to suggest that structure coefficients ought to be interpreted in structural equation modeling confirmatory factor analysis (CFA) studies in which factors are correlated. The computation of structure coefficients in explanatory factor analysis and CFA is explained. Two heuristic data sets are used to…

Thompson, Bruce; Melancon, Janet G. – 1996
This study investigated the benefits of creating item "testlets" or "parcels" in the context of structural equation modeling confirmatory factor analysis (CFA). Testlets are defined as groups of items related to a single content area that is developed as a unit. The strategy is illustrated using data from the administration of…

Chongruksa, Jiratha; Thompson, Bruce – 1996
Attachment styles have been shown to be enduring and influential, and studies of attachment phenomena require scores that are reliable and valid. The present study investigated the psychometric integrity of scores on the Adult Attachment Scale using data from 283 college students. This instrument is an 18-item Likert scale that is an expansion of…

Kieffer, Kevin M.; Thompson, Bruce – 1999
As the 1994 publication manual of the American Psychological Association emphasized, "p" values are affected by sample size. As a result, it can be helpful to interpret the results of statistical significant tests in a sample size context by conducting so-called "what if" analyses. However, these methods can be inaccurate…
