Measuring Confidence for Basic Domains of Vocational Activity in High School Students

These studies report the development and psychometric evaluation of a version of the Expanded Skills Inventory designed for use with high school students. The resulting inventory contains 14 eight-item scales measuring self-efficacy with respect to dimensions of vocational behavior comparable in specificity to the Basic Interest dimensions of the Strong Interest Inventory. The self-efficacy, or confidence, measures were internally consistent and were related to the appropriate Holland confidence theme and to parallel measures of vocational interest. Patterns of gender and ethnic group differences were generally consistent with previous research findings.
