Confirmatory Factor Analysis of the Test of English as a Foreign Language. TOEFL Research Reports, Report 32.
Hale, Gordon A.; And Others
Previous studies found inconsistent results about the factor structure of the Test of English as a Foreign Language (TOEFL), with one study finding a two-factor structure and the other, a three-factor solution. This study investigated those inconsistencies and provided further information about the TOEFL factor structure. It was hypothesized that the inconsistency between studies was related to the populations under investigation, as the earlier study used TOEFL examinees in both domestic and overseas test centers, whereas the more recent study used domestic examinees only. The present data did not support this hypothesis, however. Confirmatory factor analyses were conducted for each of several language groups, using data from a 1984 TOEFL. These analyses yielded essentially similar results for domestic and overseas populations, as well as for the combined population. In all cases, the data supported a two-factor interpretation, with the two factors related to the Listening Comprehension section and the nonlistening sections. Additional study indicated that the use of different factor analytic methodology in the two previous studies undoubtedly contributed to the inconsistency, although further study would be needed to determine exactly what aspects of the methodology played a role. Findings also indicated that the basic factor structure of the test did not change substantially between 1976 and 1984 and that a two-factor structure was in evidence for examinees in high- and low-proficiency groups. Appendixes give the factor loadings for the two-factor solution and correlations between factors in two-factor confirmatory factor analyses. (Contains 15 tables and 22 references.) (SLD)
