The present study was an attempt to investigate the vocational indecision of undergraduates in terms of ego development in adolescence. Two scales, Vocational Indecision Scale (VIS) and Identity Achievement Scale (IAS), were developed and administered to 349 university students. By factor analysis, VIS was divided into six subscales named as “Confusion” “Immaturity” “Easiness” “Moratorium” “Exploration” “Decision”, and IAS was also divided into six subscales as “Certainty” “Activity” “Acceptance” “Control” “Identity” “Intimacy”. Relations between VIS and IAS were examined mainly by multiple regression analysis and analysis of variance. The findings showed that each subscale of VIS had different relations with the subscales of IAS and each subtype of vocational indecision corresponding to the six subscales of VIS had different levels of Identity-achievement.“Decision” and “Exploration” had higher levels of Identity-achievement, while “Confusion” and “Immaturity” had lower levels. It was also noticed that some differences between sexes existed. These results gave some therapeutic suggestions to career counseling.
