Concept of indecisiveness within the HEXACO personality framework.

The Croatian translation of the IS is a valid and reliable measure. The results also confirm that the shortened 11-item version can be used as a replacement for the full 15-item version. Since there was no measure of indecisiveness in Croatian before, this instrument could be used in the future by researchers interested in this construct. It was shown that extraversion has the strongest relationship with indecisiveness, followed by conscientiousness, emotionality and agreeableness.
