The Brief Pain Inventory (BPI) is a widely used pain measurement tool. There are 2 versions, the BPI Long Form (BPI-LF) and Short Form (BPI-SF), which share 2 core scales measuring pain severity and pain interference but which use different recall periods (24 hours vs. 1 week). To date, the BPI-SF has not been validated for use in Spain. This study investigated the psychometric properties of the BPI-SF Spanish version and compared results on the core scales between BPI-LF and BPI-SF. The data came from a 3-month observational study of 3,029 nononcologic patients managed in Spanish pain units. The BPI-SF's reliability, validity, and responsiveness were assessed. The effect of different recall periods was investigated by using intraclass correlation coefficients (ICCs) to determine the strength of correlation between BPI-LF and BPI-SF. The BPI-SF showed good reliability, with Cronbach's alphas of 0.931 for the severity and interference scales, which also discriminated well between patients reporting different levels of quality of life on EuroQol-5D dimensions (between group effect sizes [ESs] over 0.8). Substantial improvements were seen on both subscales after 3 months of treatment (ES of 1.76 for pain severity and 1.51 for pain interference). Recall period did not noticeably affect scores; ICCs (95% CI) between the long and short versions were 0.946 (0.938 to 0.954) and 0.929 (0.919 to 0.939) for the severity and interference subscales, respectively. The Spanish version of the BPI-SF is a valid and reliable instrument to measure pain severity and interference.
简明疼痛评估量表（BPI）是一种广泛使用的疼痛测量工具。它有两个版本，即BPI长式（BPI-LF）和短式（BPI-SF），这两个版本共享两个核心量表，用于测量疼痛严重程度和疼痛干扰，但使用不同的回忆期（24小时与1周）。迄今为止，BPI-SF尚未在西班牙得到验证。本研究调查了BPI-SF西班牙语版本的心理测量特性，并比较了BPI-LF和BPI-SF在核心量表上的结果。数据来自对西班牙疼痛科管理的3029名非肿瘤患者进行的为期3个月的观察性研究。评估了BPI-SF的信度、效度和反应度。通过使用组内相关系数（ICC）来确定BPI-LF和BPI-SF之间的相关强度，研究了不同回忆期的影响。BPI-SF显示出良好的信度，严重程度和干扰量表的克朗巴哈系数分别为0.931，这两个量表在欧洲五维健康量表（EuroQol-5D）维度上报告不同生活质量水平的患者之间也有很好的区分度（组间效应量[ES]超过0.8）。治疗3个月后，两个子量表均有显著改善（疼痛严重程度的ES为1.76，疼痛干扰的ES为1.51）。回忆期对分数没有明显影响；长式和短式版本在严重程度和干扰子量表上的ICC（95%CI）分别为0.946（0.938至0.954）和0.929（0.919至0.939）。BPI-SF西班牙语版本是测量疼痛严重程度和干扰的有效且可靠的工具。
