The aim of this study was to perform a cross-cultural adaption and validation of the Global Pain Scale (GPS) to produce a Spanish-language version (GPS-Sp) and to determine the psychometric properties of this instrument. The GPS was cross-culturally translated into Spanish following the guidelines of the International Society for Pharmacoeconomics and Outcomes Research. The initial study population was composed of 384 patients recruited from February to May 2021. All participants were aged at least 18 years and were currently experiencing pain. All gave signed informed consent to take part and completed the Brief Inventory-Sp and GPS-Spain questionnaires. Cronbach's ɑ and test/retest reliability values were calculated and floor/ceiling effects analyzed. Construct validity was assessed by confirmatory factor analysis (CFA). The 370 patients included in the final analysis presented the following characteristics: 36.2% were male and 63.8% were female; mean age 42.6 (19-88) years; mean body mass index 24.99. Internal consistency was good. The Cronbach's ɑ for GPS-Sp was 0.86 and the intraclass correlation coefficient was 0.94 (95% CI; 0.87-0.97). Five main explanatory factors were identified by CFA, which produced the following values: RMSEA = 0.057; CFI = 0.807; GFI = 0.809; NFI = 0.763. No floor/ceiling effect was observed. The GPS-Sp is a valid, reliable and sensitive instrument for assessing pain in a Spanish-speaking population and could facilitate pain relief in this population.
本研究的目的是对全球疼痛量表（GPS）进行跨文化调适和验证，以生成西班牙语版本（GPS-Sp），并确定该工具的心理测量特性。按照国际药物经济学与结果研究学会的指南，将GPS进行跨文化翻译为西班牙语。初始研究人群由2021年2月至5月招募的384名患者组成。所有参与者年龄至少18岁，且目前正在经历疼痛。所有参与者均签署了知情同意书并完成了西班牙语简短量表和GPS-西班牙问卷。计算了Cronbach's α系数和重测信度值，并分析了地板效应/天花板效应。通过验证性因子分析（CFA）评估结构效度。最终分析纳入的370名患者具有以下特征：男性占36.2%，女性占63.8%；平均年龄42.6（19 - 88）岁；平均体重指数24.99。内部一致性良好。GPS-Sp的Cronbach's α系数为0.86，组内相关系数为0.94（95%置信区间；0.87 - 0.97）。CFA确定了五个主要解释因素，其值如下：RMSEA = 0.057；CFI = 0.807；GFI = 0.809；NFI = 0.763。未观察到地板效应/天花板效应。GPS-Sp是一种有效、可靠且敏感的工具，可用于评估说西班牙语人群的疼痛情况，并有助于该人群缓解疼痛。
