Comparison Study of the Paper, Personal Computer (PC), and Internet Versions of Holland’s Self-Directed Search

The equivalence of three different modes of administration of the Self-Directed Search (SDS) was studied with 93 college students. Scale scores and congruence were compared for the paper, personal computer (PC), and Internet versions of the SDS. Student preferences for different versions were also examined. Results showed significant positive correlations between the Internet, PC, and paper versions of the SDS on both scale scores and a measure of congruence. Overall, students preferred a computer format (either PC or Internet) to the paper version, but there was no strong preference when comparing PC and Internet versions.
