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.
目的
确定以人为中心的物理治疗治疗关系量表（PCTR-PT）的心理计量学特性，以找到该工具最合适的拟合度。
方法
邀请在西班牙 9 家医院的物理治疗服务中接受治疗的患者完成 PCTR-PT 量表的 31 个项目。为了选择最合适的 PCTR-PT 项目，使用最大似然和斜交旋转（promin）方法进行了探索性因子分析（EFA）。通过验证性因子分析（CFA）分析因子有效性、拟合优度和心理计量学特性。计算了收敛（CFA）和判别有效性。使用 Cronbach 的 alpha 系数验证内部一致性。使用组内相关系数（ICC）检查时间稳定性。
结果
366 名 18 岁以上接受至少 15 次物理治疗的患者完成了问卷。探索性因子分析的结果显示，该工具具有 4 个因子的 15 个项目[关系纽带（N 个项目=4）；个性化合作（N 个项目=4）；专业授权（N 个项目=3）和治疗性沟通（N 个项目=4）]，解释了该工具总变量的 78.4%。验证性因子分析进一步证实了四结构模型。该工具的可靠性通过四个维度的 Cronbach 的 alpha 得到了验证，所有维度都高于.70，范围从.84（个性化合作）到.91（专业授权）。α=0.94。在两周的间隔内进行了测试-重测，表明该量表具有适当的稳定性（ICC=0.900）。
结论
以人为中心的物理治疗治疗关系量表（PCTR-PT）是一种有用、有效和适用的工具，可用于评估物理治疗干预过程中的以人为中心的治疗关系。研究 PCTR-PT 量表的预测能力（敏感性和特异性）将很有趣。
