Applied Psychological Measurement, 15, 99-101. doi:10.1177/014662169101500112doi:10.1177/014662169101500112https://hdl.handle.net/11299/114154Some practicality clarifications for use of the composite-reliability formula developed in Rozeboom (1989) are described. A microcomputer program is announced to implement the calculations, and a prior source of related work is identified. Index terms: composite reliability, item weighting, nonequivalent subtests, non-homogeneous item composites.enArticle
