The Job Descriptive Index (JDI) and Job in General Scale (JIG) underwent a comprehensive review and update in January 2009. A total of 1,485 working adults participated in the update, and participants were representative of the U.S. working population on key variables such as age, education, and tenure. This update was a collaboration between Amplitude Research and the industrial/organizational program at Bowling Green State University (BGSU) - - a leader in creating normative scoring indexes to measure employee job satisfaction. This review resulted in minor changes in some of the questions comprising the indexes, update of the nationwide norms, and the creation of completely new industry group norms. The industry group norms are exclusive to Amplitude Research.
