Incremental variance of the core self-evaluation construct compared to fluid intelligence and personality traits in aspects of decision-making
Annamaria Di Fabio, Letizia Palazzeschi
This study investigated the role of fluid intelligence, personality traits and core self-evaluation in relation to aspects of decision-making (career decision-making difficulties, decisional styles, indecisiveness). The Advanced Progressive Matrices (APM), the Big Five Questionnaire (BFQ), the Core Self-Evaluation Scale (CSES), the Career Decision-making Difficulties Questionnaire (CDDQ), the Melbourne Decision Making Questionnaire (MDMQ), and the Indecisiveness Scale (IS) were administered to 143 Italian high school students. The study revealed that the core self-evaluation construct added a significant percentage of incremental variance compared to variances due to fluid intelligence and personality traits with respect to aspects of decision-making. The results highlight the role of the core self-evaluation construct and its relationship with aspects of decision-making thereby offering new research and intervention perspectives.
