This study provides evidence concerning the construct validity of the Task-Specific Self-Efficacy Scale (TSOSS) and the Skills Confidence Inventory (SCI), both measures of self-efficacy with respect to basic domains of vocational behavior. Relationships between similarly named scales, that is, TSOSS-Verbal/interpersonal with SCI-Social, TSOSS-Quantitative with SCI-Investigative, TSOSS-Physical with SCI-Realistic, and TSOSS-Aesthetic with SCI-Artistic, were high, ranging from r = .50 to .80. Negligible relationships of self-efficacy to measured ability and significant relationships of self-efficacy with respect to Verbal/interpersonal and Social dimensions to career indecision were also reported and discussed.
