As a relatively new area of study in creative research, creative confidence and its variables have yet to be studied in a comprehensive way. The purpose of this thesis is to better understand the impact of creative confidence on team functioning when positive and negative affect are controlled. Creative confidence is defined as a measure of two variables: creative self-efficacy and creative agency. Team functioning is defined as a measure of five variables: trust, productive conflict, decision commitment, accountability, and goal commitment. This study surveyed 395 employed adults, 18 years or older living in the United States. Participants answered 5-point Likert scale items using Brockhus et al.’s Questionnaire on Creative Self-Efficacy, Royalty et al.’s CompetencyBased Creative Agency Scale, Lencioni’s Team Assessment, and Mackinnon et al.’s short-form Positive and Negative Affect Schedule. Results demonstrated creative agency has a significant impact on some aspects of team functioning, while creative self-efficacy does not have a significant impact. With a more accurate understanding of creative confidence, organizations can reevaluate training and development in the workplace.
