The purpose of this research was to examine the measurement properties of a CSR Implementation Scale developed using classical test theory. Rasch analyses were employed to determine (1) the degree to which the scale meets the assumptions of the Rasch model; 2) the validity and reliability of the scale; 3) how respondents utilize the rating scale; 4) the nature of the continuum of CSR implementation; and 5) ways to optimize scale length, both in terms of eliminating redundancy and adding items where gaps in the continuum of the CSR implementation variable might occur.
