Abstract
No instrument exists that measures oncology nurses' exercise beliefs for women with breast cancer experiencing cancer-related fatigue. This article reports on the psychometric evaluation of the Nurses' Exercise Beliefs scale. There were 20 items generated for the scale from a review of the literature. An expert panel review achieved content validity of the scale. The scale was administered to 387 registered nurses and the data were analyzed. The scale content validity index (S-CVI) was .85. A 2-factor solution explained 50.4% of the variance in exercise beliefs, supporting construct validity. The factors were exercise benefits beliefs (8 items, α = .94) and exercise barriers beliefs (12 items, α = .81). The findings support the subscales as valid and reliable tools.
