Comparison of Error Rates on the 1990 and 1994 Revised Self-Directed Search

Abstract

This study compared the error rates on the 1990 and 1994 versions of the Self-Directed Search for a sample of 91 high school students (44 boys, 47 girls) of junior and senior standing. The two versions are different primarily in the wording and inclusion or exclusion of specific items. However, because both versions appear to be straightforward and involve relatively few transformations of subscale scores by the user, it was hypothesized that no significant differences in error rates would be found between the two versions. Results of a z test confirmed the hypothesis.
