Abstract: The purpose of this research was to validate the scores of a short form of a new instrument, l’Épreuve de décision vocationnelle, forme scolaire (EDV-9S; vocational assessment test), which measures six indecision-related problems (lack of self-knowledge, lack of readiness, lack of method in decision making, lack of information, external barriers, and dysfunctional beliefs). In Study 1 (n = 778; Mage = 17.7 years; female = 55.4 %), we first assess the reliability and factorial validity of the EDV-9S scores. Subsequently, 24 of 48 items were selected using Rasch modeling. In Study 2 (n1 = 757; Mage = 18.0 years; female = 55.9 %), we assess the reliability, factorial validity, and convergent and divergent validity of the short form scores and their invariance across gender and over time. Findings from both studies suggest that the original as well as the short form scores present adequate psychometric properties and could be used to assess indecision problems in French-speaking students in higher education.
