The aim of this study was to determine the relationship between state and trait anxiety with career indecision of Iranian undergraduate students. According to the literature anxiety has a strong impact on career indecision among students. However, there is controversy in research findings regarding the contribution of state and trait anxiety to career indecision. Despite many studies on the relationship between state and trait anxiety with career indecision, very limited research has been conducted in this area among Iranian students. For this purpose, 150 undergraduate undecided students from 3 universities in Khozestan Iran, completed the career decision scale (CDS), and the State Trait Anxiety Inventory (STAI). Results of regression analysis showed that trait anxiety had a stronger impact on career indecision than did state anxiety. In addition, the relationship between anxiety components and career indecision was reported as positive. Implications for further research are discussed in the paper.
