The purpose of the present study is to evaluate the construct validities of two subtypes of personal indecisiveness (exploratory indecisiveness and impetuous indecisiveness) by examining their relationships to certain personality characteristics (locus of control, self-esteem, and irrational beliefs). The sample consists of 399 Turkish freshman university students (194 male and 205 female) from Gazi University, Ankara, Turkey. The results indicate that low self-esteem is a strong predictor of exploratory indecisiveness. External locus of control and high level of irrational beliefs are also positively predictive of exploratory indecisiveness. External locus of control is a strong predictor of impetuous indecisiveness. However, self-esteem and irrational beliefs are not significant predictors of impetuous indecisiveness. The implications of these findings for career counselors and for future research are discussed.
