The Pain Relief Motivation Scale (PRMS) was administered to chronic pain sufferers and predicts their psychological well-being. However, the Chinese version of the PRMS has not undergone psychometric validation.
The PRMS will be psychometrically validated in patients with neuropathic pain-induced chronic pain from mainland China.
This cross-sectional study involved 340 patients with neuropathic chronic pain from China. The measurability of the Chinese version of the PRMS was determined by the critical ratio between items, and reliability was confirmed by Cronbach's alpha coefficient. The study also examined the validity of the construction and criterion validity of the Chinese PRMS.
The Chinese version of the PRMS had critical ratio (CR) values ranging from 4.044 to 15.977 (p < 0.05). The Cronbach's alpha coefficient for the scale was 0.821, and the Cronbach's alpha coefficients for the subscales ranged from 0.663 to 0.961. Exploratory Factor Analysis (EFA) showed that five variables accounted for 77.73% of the total variance. The results of the Confirmatory Factor Analysis (CFA) supported the framework for the assessment of the 21-item PRMS. The Chinese version of the PRMS was positively correlated with the General Self-Efficacy Scale in the correlation validity analyses (r = 0.458, p < .001).
The Chinese version of the PRMS has powerful validity and reliability and can be used to assess the level of the motivation for pain alleviation in people with pain, serving as a reference for the development of intervention programs for healthcare providers.
疼痛缓解动机量表（PRMS）已应用于慢性疼痛患者，并可预测其心理健康状况。然而，PRMS的中文版尚未经过心理测量学验证。
对中国大陆神经性疼痛所致慢性疼痛患者进行PRMS的心理测量学验证。
这项横断面研究纳入了340名来自中国的神经性慢性疼痛患者。通过项目间的临界比确定PRMS中文版的可测量性，并用Cronbach's α系数确认信度。该研究还检验了中文版PRMS的结构效度和效标效度。
PRMS中文版的临界比（CR）值范围为4.044至15.977（p<0.05）。该量表的Cronbach's α系数为0.821，各分量表的Cronbach's α系数范围为0.663至0.961。探索性因子分析（EFA）显示，五个变量占总方差的77.73%。验证性因子分析（CFA）的结果支持了21项PRMS的评估框架。在相关性效度分析中，PRMS中文版与一般自我效能量表呈正相关（r = 0.458，p <.001）。
PRMS中文版具有较强的效度和信度，可用于评估疼痛患者的疼痛缓解动机水平，为医护人员制定干预方案提供参考。
