The purpose of this descriptive comparative study is to compare the levels of decisional involvement of staff nurses between one Midwestern health care system in the United States with a nongovernmental University hospital in Turkey. The Decisional Involvement Scale was used for data collection. U.S. (n = 163) and Turkey (n = 50) staff nurses were included in the study. Both samples preferred more decisional involvement than they currently experienced. However, Turkish nurses experienced and preferred lower levels of decisional involvement than the U.S. sample. Shared governance structures may be a strategy used to enhance staff nurse decisional involvement.
