This study was conducted to develop a valid and reliable indigenous self-report measure of indecisiveness and its empirical evaluation. Sample was consisted of 300 students. The items were constructed on the bases of previous literature and information received by focus groups. The whole Item pool of Indecisiveness Scale was subjected to principal component analyses and two factors were extracted including trait indecisiveness and state indecisiveness. The item total correlation for the items of both factors state Indecisiveness and trait indecisiveness ranged from .50 to .72 (p < .001). Reliability analyses proved that over Indecisiveness Scale and both its subscales have excellent alpha reliability. In order to test the construct validity, Indecisiveness Scale and its subscales were correlated with indecisiveness scale by Germeijes and De Boeck (2002).
