The expectancy-value theory (EVT) and the control theory both provide a framework for explaining how personality facets might be impacted. In two pilot studies, (bottoms-up interventions) were used to determine if facets of personality could change. Study one examined the impact of brief Behavioral Activation training on facets of Conscientiousness. Study two examined the impact of instructional feedback and monitoring (coaching) on facets relating to the big five personality traits. Findings showed a 5-week Behavioral Activation training increased both logical thinking and preparedness (facets of conscientiousness). Additionally, 12-weeks of coaching lead to changes in four of the big five personality traits. In both studies, these behavioral changes were significantly related to changes in emotional well-being and physical health perceptions., Author(s): Amber R. Massey-Abernathy [sup.1] , Dallas N.
