As part of a research program designed to explicate the construct "power," a formulative research strategy was used to identify 37 personal orientations toward power. A preliminary instrument based on these orientations was administered to samples of corporate executives, government employees, law enforcement personnel, and sales associates. A final instrument, based on the seven factors common to all four samples, was checked for reliability and validity. Validity checks included correlating the seven power orientation scores with the sentencing decisions of district court judges, the leadership styles of managers, and the dogmatism of business and community leaders. (Appendixes include data tables and a copy of the power orientation scale.) (Author/FL)
