The psychometric properties of the person-centered therapeutic relationship in physiotherapy scale

Abstract

Objective To determine the psychometric properties of the Person-Centered Therapeutic Relationship in Physiotherapy Scale (PCTR-PT) in order to find the most appropriate fit for the tool. Methods Patients who had received treatment at the physiotherapy service of nine hospitals in Spain were invited to complete the 31 items of the PCTR-PT scale. To select the most appropriate items of the PCTR-PT, an exploratory factorial analysis (EFA) was performed using the maximum likelihood and oblique rotation (promin) methods. Factor validity, goodness-of-fit and psychometric properties were analyzed by confirmatory factor analysis (CFA). Convergent (CFA) and discriminant validity were calculated. Internal consistency was verified using the Cronbach's alpha coefficient. The intraclass correlation coefficient (ICC) was used to examine temporal stability. Results 366 patients over 18 years old who had received, at least, 15 physiotherapy treatment sessions completed the questionnaire. The results of the exploratory factor analysis revealed a tool with 15 items in four factors [Relational Bond (N items = 4); Individualized Partnership (N items = 4); Professional Empowerment (N items = 3) and Therapeutic Communication (N items = 4)], explaining 78.4% of the variance of the total variables of this tool. The confirmatory factor analysis further confirmed the four-structure model. Reliability of the tool was approved by Cronbach's alpha in all four dimensions, as all were above .70, ranging from .84 (Individualized Partnership) to .91 (Professional Empowerment). = 0.94. Test-retest was performed with two-week intervals, indicating an appropriate stability for the scale (ICC = 0.900). Conclusion The Person-Centered Therapeutic Relationship in Physiotherapy Scale (PCTR-PT) is a useful, valid and applicable instrument to evaluate the person-centered therapeutic relationship during physiotherapy interventions. It would be interesting to investigate the predictive capacity (sensitivity and specificity) of the PCTR-PT scale.

Development of the Physiotherapy Therapeutic Relationship Measure

“…While the ceiling effects for the total scale were not reported, the individual items all showed ceiling effects, a common issue in measures of relational constructs (e.g. working alliance, patient satisfaction) [25]. The content of the PCTR-PT scale shares many similarities with the P-TREM [24].…”

“…To our knowledge, the P-TREM is the first English-language measure based on a discipline-specific model of therapeutic relationship. There has been one other measure developed based on a discipline-specific model of person-centred therapeutic relationships (PCTR-PT) using similar methodologies [24,25]. It was constructed to have four dimensions 'Relational Bond', 'Individualized Partnership', 'Professional Empowerment', and 'Therapeutic Communication', and all have good internal consistency (co-efficient alpha values between .86 and .91) [25].…”

Die personenzentrierte therapeutische Beziehung in der Physiotherapie: Entwicklung und Inhaltsvalidität eines Messinstruments

“…Im November 2020 publizierten Rodríguez Nogueira O et al (2020) in einem Folgeartikel die Ergebnisse der Evaluation der psychometrischen Eigenschaften und das finale Messinstrument [7]. Nach einer Übersetzung und interkulturellen Anpassung ermöglicht dieses Messinstrument die weitere Erforschung der therapeutischen Beziehung in der Physiotherapie in Deutschland.…”

Translation and validation of stroke impact scale-16 in Urdu for Pakistan

“…Although performance-based functional tools are considered necessary, 1 self-reported physical functioning scales are increasingly being valued in rehabilitation to design appropriate therapeutic interventions for stroke patients. 2 Patient-reported physical functioning instruments with suitable psychometrics are still scarce in Urdu language for Pakistani stroke patients because such scales are mostly available in English or foreign languages.…”
