Peer reviewedHenson, Robin K.; Thompson, Bruce – Measurement and Evaluation in Counseling and Development, 2002
T. Vacha-Haase (1998) proposed her "reliability generalization" methodology to characterize (a) typical score reliability for a measure across studies, (b) the variability of score reliabilities, and (c) what measurement protocol features predict the variability in score reliabilities across administration. The present article provides…

Peer reviewedThompson, Bruce; Cook, Collen – Educational and Psychological Measurement, 2002
Conducted a reliability generalization meta-analysis of subscale and total scale scores on the Web-administered LibQUAL+ (tm) (Cook and others, 2002), a measure of library service quality. Data for 18,161 participants from 43 universities show that score reliabilities are remarkably invariant across campuses and different over groups. (SLD)
