Development and Initial Validation of the Career Decision-Making Ambiguity Scale

The dual-process theory of career decision-making (DTC) adds to the conversation about understanding and facilitating career decision-making from a more realistic and inclusive perspective and highlights the joint operation of decision ambiguity and ambiguity management strategies in career decision-making. However, a psychometrically sound measure of decision ambiguity is lacking. Thus, the current study used two samples of U.S. college students to develop and initially validate a measure of decision ambiguity (CDMA). Study 1 (n = 195) developed the CDMA and found initial evidence for a unidimensional structure. Study 2 (n = 271) cross-validated the unidimensional structure of the CDMA and supported the convergent, discriminant, concurrent, and incremental validities of the CDMA. Specifically, the results supported (1) the differential associations of the CDMA with need for information and with neuroticism/negative affectivity, lack of readiness, and interpersonal conflicts, (2) the positive association between the CDMA and choice/commitment anxiety, and (3) the incremental predictions of the CDMA for career decidedness, career certainty, and major satisfaction over and beyond need for information. Therefore, the current study offers a psychometrically sound measure of decision ambiguity, which has potential to facilitate the scientific inquiry and social justice application of the DTC.
