Essential elements of the nursing practice environment in nursing homes: Psychometric evaluation.

AIMS AND OBJECTIVES: To develop and psychometrically test the Essentials of Magnetism II in nursing homes. BACKGROUND: Increasing numbers and complex needs of older people in nursing homes strain the nursing workforce. Fewer adequately trained staff and increased care complexity raise concerns about declining quality. Nurses' practice environment has been reported to affect quality of care and productivity. The Essentials of Magnetism II © measures processes and relationships of practice environments that contribute to productivity and quality of care and can therefore be useful in identifying processes requiring change to pursue excellent practice environments. However, this instrument was not explicitly evaluated for its use in nursing home settings so far. DESIGN: In a preparatory phase, a cross-sectional survey study focused on face validity of the essentials of magnetism in nursing homes. A second cross-sectional survey design was then used to further test the instrument's validity and reliability. METHODS: Psychometric testing included evaluation of content and construct validity, and reliability. Nurses (N = 456) working at 44 units of three nursing homes were included. RESULTS: Respondent acceptance, relevance and clarity were adequate. Five of the eight subscales and 54 of the 58 items did meet preset psychometric criteria. CONCLUSIONS: All essentials of magnetism are considered relevant for nursing homes. The subscales Adequacy of Staffing, Clinically Competent Peers, Patient Centered Culture, Autonomy and Nurse Manager Support can be used in nursing homes without problems. The other subscales cannot be directly applied to this setting. IMPLICATIONS FOR PRACTICE: The valid subscales of the Essentials of Magnetism II instrument can be used to design excellent nursing practice environments that support nurses' delivery of care. Before using the entire instrument, however, the other subscales have to be improved.
