Adaptation of the person centered therapeutic relationship patient version (PCTR-PT) to a version for physiotherapists (PCTR-PHYS) and evaluation of its psychometric properties

# metadata.dc.description.abstract[].value
Background and purpose: The therapeutic relationship is a central component for developing person-centered care within physiotherapy services. However, it is necessary to understand how this relationship is perceived by both parties involved. The Person Centered Therapeutic Relationship-Patient scale (PCTR-PT) was constructed to identify patients' perceptions. No instruments are currently available to correlate patients' and physiotherapists' perceptions of the therapeutic relationship. This study sought to adapt the PCTR-PT to develop a version for physiotherapists, the Person Centered Therapeutic Relationship Scale for Physiotherapists (PCTR-PHYS) and to determine its psychometric properties. Methods: A three-stage study was performed: (1) item generation, (2) pretesting of the questionnaire, (3) analysis of psychometric properties. Factor validity and psychometric properties were analyzed by confirmatory factor analysis (CFA). Convergent validity was calculated. Internal consistency was verified using the Cronbach's alpha coefficient. The intraclass correlation coefficient (ICC) was used to examine temporal stability. Results: Thirty-three physiotherapists participated in two rounds of cognitive interviews and 343 participated in the analysis of psychometric properties. The CFA confirmed the four-structure model. Reliability of the tool was confirmed by Cronbach's alpha (α = 0.863) for all four dimensions, as all were above 0.70, ranging from 0.704 (relational bond) and 0.898 (therapeutic communication). Test-retest was performed with 2-week intervals, indicating an appropriate stability for the scale (ICC = 0.908). Discussion: The Person Centered Therapeutic Relationship Scale for Physiotherapists is a useful, valid and applicable instrument to evaluate the person-centered therapeutic relationship during physiotherapy interventions. It will enable the comparison of patients' and physiotherapists' perceptions. To provide person-centered care in physiotherapy services, there is a clear need to incorporate specific resources into clinical practice to evaluate the quality of the therapeutic relationship from the perspective of both the persons being treated and the professionals providing care.
