Personal Growth Initiative is an individual's active, intentional engagement in the process of personal growth. The studies presented here have provided initial support for the construct's validity in relation to several other psychological constructs. The Personal Growth Initiative &ale ostensibly measures this construct and the studies presented here have provided support for the internal consistency, temporal stability, and convergent and discriminant validity of scores on this instrument. Future research should further delineate the Personal Growth Initiative construct and test its usefulness in research and practice.
