Self-efficacy beliefs and self-rated abilities are conceptually overlapping
constructs that have emerged from two parallel literatures in career psych
ology. The present investigation employed three different analytic strategi
es to assess empirically whether they represent unique constructs. In the f
irst analysis, confirmatory factor analyses of measures of each of these tw
o constructs revealed that a two-factor model fit the data better than did
a one-factor model. Second, it was found that LISREL estimates of self-effi
cacy beliefs were more highly related to vocational interests and perceived
career options than were estimates of self-rated abilities. Third, the rel
ation of ability self-estimates to interests was found to be mediated by se
lf-efficacy beliefs. The implications of these findings for theory and prac
tice are considered.
