Convergent and discriminant validity of five interest inventories

This study investigated whether interest inventories that purport to measure the same constructs actually yield scores that correspond. The study examined the empirical relation of scores for similarly and same-named scales on five widely used interest inventories: the Campbell Interest and Skills Survey, the Kuder Occupational Interest Survey-Form DD, the Self-Directed Search, the Strong Interest Inventoty-Skills Confidence Edition, and the Revised Unisex Edition of the, ACT Interest lnventory. Comparisons were made among scores for (a) vocational interests measured by homogeneous, rationally based scales; (b) occupational interests measured by heterogeneous, criterion-based scales; and (c) self-efficacy for RIASEC tasks. The participants consisted of 80 women and 38 men employed as career counseling practitioners and professors. Results from analyses of multitrait-multimethod matrices indicated that similarly and same-named scales correlated moderately and that, with few exceptions, these matched scales demonstrated convergent and discriminant validity. These conclusions were interpreted by distinguishing between the linguistic explication and operational definition of constructs in theories of vocational and occupational interests. The implications of these interpretations were considered for both the science of vocational psychology and the practice of career counseling. Future research should investigate both the profile validity and the interpretive validity of interest inventories that yield scale scores derived from different scaling strategies.

The career development inventory in review: Psychometric and research findings
choice; guidance; identity; model; Psychology; Self-Directed Search; students; validity; vocational maturity; work
First published over 15 years ago, the Career Development Inventory (CDI; Super, Thompson, Lindeman, Jordaan, & Myers, 1979) measures readiness for making educational and vocational choices and operationally defines Super's structural model of adolescent career maturity. The present article systematically analyzes the body of literature that has evaluated and explicated the psychometric characteristics and uses of the CDI. This review examines empirical findings pertinent to the reliability, factor structure, and validity of the CDI; evaluates the instrument's present status; and identifies topics for future research.
