Abstract

|
The purpose of this study was to develop a scale that measures self-improvement of college students(self-improvement scale [SIS]) and to assess evidence of validity and reliability of its scores. Four-phases of the study are presented detailing (a) individual intensive interviews (n = 5), (b) exploratory factor analysis (EFA; n = 226), (c) confirmatory factor analysis (CFA; n = 1,067), and (d) cross-validity test (n = 261). An initial pool of 40 items were developed through intensive individual interviews, followed by the preliminary EFA resulting in 24 items. The final CFA model yielded 15 items within four factors detailing (a) future design, (b) career development, (c) emotional control, and (d) life management, with the internal reliability of .842 for the SIS total score. Implication for the study is discussed.
