APA Dictionary of Psychology

a 72-item job satisfaction scale used to measure the attitudes of employees in areas such as work, supervision, pay, promotions, and coworkers. Each item is an adjective or short phrase (e.g., “boring,” “good opportunities for promotion”), and the participant writes Y (yes), N (no), or ? (cannot decide) to indicate whether the item applies to their job. Originally published in 1969, the JDI has undergone three major revisions, most recently in 2009. [developed by Patricia Cain Smith, Canadian psychologist Lorne M. Kendall (1933–1977), and U.S. organizational psychologist Charles L. Hulin (1936–  )]
