Content:
The study references theoretical underpinnings, and the MedEdPortal states that the items were based on "field research," but the content validity of the instrument is not described in this study.
Response Process:
A total of 878 patients (64% response rate) completed patient survey items, and n=338 (51%) provider completed the RCS. Provider response rates varied by profession and by hospital.
Internal Structure:
Cronbach's alpha for the 7 dimensions ranged from 0.717 to 0.840 and 0.849 for the total instrument, which is adequate for formative evaluation or low-stakes assessment purposes.
Relation to Other Variables:
See below, which describes significant patient benefits of positive relational coordination.
Consequential:
Patient reports of care quality were significantly related to overall relational coordination (p <0.001) and for each of the 7 separate dimensions. Post-operative pain was reduced, and post-operative functioning were both significantly related to the frequency of communication (p = 0.044), the strength of communication (p = 0.035), and the degree of mutual respect among care providers (p = 0.030). Length of stay was shortened by 53.8% in teams reporting high relational coordination; LOS was also significantly related to each of the 7 dimensions.
