Abstract: Despite of the superiority of retrospective pretest over the pretest-posttest design in attenuating response-shift bias, researchers are alarmed with the pressing issue that the use of retrospective self-reporting methods can be even more vulnerable to validity threats. This study was designed to investigate the influence of response bias using three types of retrospective self-reporting methods to measure change experienced by participants in an educational training program. Results indicate that the measurement of change varied among the three types of retrospective self-reporting methods. The perceived change method produces the highest increase in reported change, followed by the post+perceived change method, and the post+retrospective pretest method with the smallest amount of change. The post+retrospective pretest was found to have greater susceptibility to response bias influences than perceived change and post+perceived change methods, including recall bias, hindsight bias, and effort justification. A discussion of results focuses on methodological implications to measurement and evaluation.
