 B13 I am not comfortable teaching in an interactive way* 4    
 B14 I am not comfortable giving students ongoing feedback because it might spur on uncomfortable interactions 3    
 B15 [Evidence-based teaching] is simply not my style of teaching 1    
  1. *Indicates the item is significantly related to implementation through a two-tailed Spearman binary correlation (p < .05)
  2. aUnlike other barrier items, this item is positively associated with implementation. One interpretation of this pattern would be that an instructor would not perceive their colleagues as unsupportive of EBT until he or she began implementing and discussing it with colleagues (i.e., implementation would proceed perceiving this barrier), resulting in a positive relationship between item B04 and implementation
