Reliability and validity of the Therapist Collaborative Practice Scale (TCPS)

Abstract

The purpose of this study was to test the reliability and validity of the Therapist Collaborative Practice Scale (TCPS). The subjects were therapists in a recovery rehabilitation ward. For reliability testing (n=53), TCPS was performed twice at 2-week intervals, ICC=0.97 (95% CI; 0.95-0.98, p<0.01), and the Bland-Altman plot converged within limits of agreement. Validation (n=210) showed moderate correlations (r>0.60) with two existing scales assessing interprofessional collaboration. These results suggest that the TCPS has good reliability and validity as a scale to assess therapists' interprofessional collaborative practice.
