This measurement study reports on the results of statistical analyses of scores generated by the Kambara (1982, 1987) Locus of Control Scale (K-LoCS). The scale has two versions: the short form, K-LoC18 (18 items, 1982) and the long form, K-LoC43 (43 items, 1987). A data set (N=1125) was collected from Japanese high school students, and four models were tested a priori; two were the originally hypothesized models for the short and long forms, and two were based on EFA derived models present in the literature. The purpose of this study was to evaluate the plausibility of these models for an instrument which has been widely used in the Japanese research context; thus far in the absence of such a priori testing. The background rationale for this is also that measuring locus of control might serve as a viable proxy for measuring learner autonomy, given that the two are notionally related. The results of this study indicated that all models represented unsatisfactory fit to the dimensionality of the data. This has implications for past and future research, which relies upon structurally valid measurement, and also has implications for the practitioner.
