The relationships among growth mindset for public speaking (i.e., the implicit theory that public speaking abilities can be developed and improved) and beliefs about the nature of public speaking, public speaking apprehension (PSA), and self-perceived public speaking competence (SPPSC) were investigated in intensive and traditional formats of a general education public speaking course. In general, growth mindset was associated with lower PSA, higher SPPSC, and more sophisticated beliefs about public speaking. Mindset remained somewhat stable, PSA significantly decreased, and SPPSC significantly increased from the beginning to the end of the course. More sophisticated beliefs about public speaking as an expressive, transformational, and audience-centric endeavor also tended to increase. However, there were several important differences between intensive and traditional formats. In particular, changes in the intensive format were more consistent across variables and had larger effect sizes.
