A study reanalyzed the 1977 original form of the Self-Directed Learning Readiness Scale (SDLRS) developed by Guglielmino. It questioned whether there is an intracultural and intercultural factorial consistency, whether raters would reconfirm the eight-factor solution, and whether raters would reconfirm the main characteristics of a "highly self-directed learner." To answer the first question, the 41 items of the SDLRS were translated into German and administered to a German sample (n=460). Simultaneously, the original instrument was completed by a U.S. sample (n=226). The Guglielmino sample consisted of 307 respondents. The second question was answered by 10 persons trained in empirical research methods, and the third by 20 adult education practitioners. Findings indicated that the factor solutions were not stable, even for the U.S. sample. Twenty-one of the 41 of the factor solution for the U.S. sample were multistructured. Only 2 of 41 items were structurally loading on corresponding factors over all samples. Ten raters were asked to assign the 41 items of the original instrument to Guglielmino's 8 factors. Eleven items were assigned to the same original eight factors. Results indicated the raters had problems in revalidating the original factor structure. Twenty adult education practitioners were asked to assign the 41 items to 14 characteristics. Eleven or more of them distinctly assigned six items to one characteristic.
