Registered Dietitian Nutritionists’ Attitudes Toward Interprofessional Health Care Teams: A Cross-Sectional Survey

Registered dietitian nutritionists (RDNs) are important members of interprofessional health care teams; yet, there is limited research of RDN perspectives of interprofessional teams. To examine associations between the characteristics of RDNs and their attitudes of team-based care (TBC). A cross-sectional electronic Qualtrics survey encompassing demographic questions, the Attitudes Toward Interdisciplinary Health Care Teams (ATIHCT) scale, and additional interprofessional-related items was distributed to RDNs during January 2020. A total of 5018 RDNs from various regions/specialties in the United States were recruited primarily via direct email from a random list of RDNs obtained through the Commission on Dietetic Registration. The final sample was N = 616; 12.3% of RDNs and 88.1% of RDNs who initiated the survey. ATIHCT subscale scores, which measure attitudes regarding efficiency of TBC and service quality of TBC. Multiple linear regression modeled area of specialty, time with RDN credential, location, sex, frequency of TBC, and how valued the RDN perceived him or herself to be as independent variables, with ATIHCT subscales as outcome variables. Data were subjected to confirmatory factor analysis to determine appropriate use of the ATIHCT scale in the sample. Foodservice (β = –1.48; P = .004) and sports nutrition RDNs (β = –2.58; P = .014) had lower scores for attitudes regarding efficiency of TBC (subscale 1) than clinical RDNs. Greater perceived value of the RDN was associated with higher scores for attitudes regarding efficiency (β = .66; P < .001). Greater perceived value of the RDN (β = .13; P = .03) was associated with higher scores for attitudes regarding service quality of TBC (subscale 2). Specialty and perceived RDN value are associated with more favorable interprofessional attitudes among RDNs. To support positive attitudes regarding interprofessional collaboration, efforts should be honed to foster appreciation and clarity of the RDN’s role in TBC.
