Abstract
BACKGROUND: Scope of practice enactment is poorly understood in the primary care setting. PURPOSE: The following research objectives were addressed: (1) to revise and adapt the Actual Scope of Practice (ASCOP) questionnaire for use in the primary care setting, and (2) to determine internal consistency, construct validity, and sensitivity of the modified instrument. METHODS: To address the first objective, a narrative literature review and synthesis and an expert panel review was conducted. To address the second objective, a cross-sectional survey of 178 registered nurses who worked in primary care was conducted. RESULTS: The ASCOP, with few modifications, addressed key attributes of nursing scope of practice in the primary care setting. The modified instrument yielded acceptable alpha coefficients ranging from 0.66 to 0.91. Total mean score of 4.8 (SD = .67) suggests that registered nurses within interprofessional primary care teams almost always engage in activities reflected in the modified instrument. CONCLUSIONS: The modified instrument is the first instrument validated to measure nursing scope of practice enactment in the primary care setting. Findings from this study support the use of the modified ASCOP questionnaire as a reliable and valid measure of scope of practice enactment among primary care registered nurses.
