Development of a Japanese Version of a Collaborative Relationship Scale between Clients and Occupational Therapists

Abstract

Objective:The success of a client-centred practice depends on the relationship between the client and therapist and on their ability to make constructive decisions together, particularly in the field of occupational therapy. The aim of this study was to develop a Occupational Therapy Collaborative Relationship Scale (OTCRS) to measure the quality of such interaction. Methods: This work included constructing a draft questionnaire and testing its validity and reliability. A Rasch analysis was applied to determine its validity, and several tests were used to confirm its internal consistency. Results: After reviewing more than 130 scientific papers and books, we built explicit selection criteria for issues to be addressed in this instrument, and we developed 40 questions to be included. These were analysed using a standard content validation process and a Rasch analysis to examine confirmation validity. A nine-item scale was finalised for testing . This review process revealed the validity, high internal consistency, and item/person separation reliability of OTCRS-9. Conclusion: This study presents only the initial phase of scale development. As suggested by the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN), the OTCRS-9 score should be tested further for validity and reliability and should also be conducted in subjects of other ethnicities to improve its generalizability.

Preliminary analysis of the clinical feasibility of a practice intervention derived from the occupational therapy intervention process model for patients with stroke in the convalescence stage

“…The calculated total score in CRS is classified under three categories based on the estimated values below: poor collaborative relationship group, neutral collaborative relationship group, and good collaborative relationship group (Choji et al, 2020a, 2020b). In this study, the good collaborative relationship group demonstrated significantly higher process skills in AMPS and satisfaction in COPM compared to the poor collaborative relationship group and occupational therapists group, respectively.…”

“…The CRS between clients and occupational therapists, developed by Choji et al (2020aChoji et al ( , 2020b, is a standardized assessment simple screening tool to measure the degree of the collaborative relationship between clients and occupational therapists. A collaborative relationship in CRS is defined as the degree of shared authority between clients and occupational therapists when deciding on a client-centered approach from the client's perspective.…”

“…It is, by default, simply evaluated subjectively by occupational therapists at the clinical site. To address this issue, we have developed the Collaborative Relationship Scale (CRS) between clients and occupational therapists for use in both research and clinical practice (Choji et al, 2020a(Choji et al, , 2020b.…”
