Self-Directed Search Response Project

Many of the Holland-based interest assessments differ in the number of answer options they present to clients, with some providing clients more sensitivity with which they can indicate their level of interest. Following anecdotal client comments, a study was developed to determine whether significant changes in inventory results occurred based on the number of answer options presented, while test items remain consistent. Two versions of the Self-Directed Search (SDS)-Fifth Edition were presented to 553 participants across two subsamples (312 Mechanical Turk and 241 college students). The published version of the SDS that presents clients with two response options was used as well as an altered version presenting clients with five-answer options. The internal consistency and profile stability across versions were explored. Statistically significant differences in internal consistency were found. Moderate-to-high profile stability for individuals and across test versions was detected. Implications for future research and practice are discussed.
