The aim of this study was to develop and validate a short form of the Brazilian version of McGill Pain Questionnaire (SF-MPQ). Three hundred two patients with chronic pain filled out the validated Brazilian long form of the McGill Pain Questionnaire (LF-MPQ). Words chosen by ≥25% of the patients were selected to comprise the SF-MPQ. The Brazilian SF-MPQ consisted of 15 descriptors (8 sensory, 5 affective, and 2 evaluative) rated on a binary mode (present or absent). Four pain scores were derived by counting the words chosen by the patients for sensory, affective, evaluative, and total descriptors. The SF-MPQ showed poor internal consistency (KR-20 = 0.52) but possibly acceptable because it showed discriminant validity to discriminate patients presenting different levels and mechanisms of pain, and it was strongly correlated with the LF-MPQ. The low KR-20 coefficient could result from the small number of items. The Brazilian version of the SF-MPQ proved to be a useful instrument to evaluate the different qualities of pain. It is a reliable option to the long-form MPQ.
本研究的目的是开发并验证巴西版麦吉尔疼痛问卷简表（SF-MPQ）。302名慢性疼痛患者填写了经验证有效的巴西版麦吉尔疼痛问卷长表（LF-MPQ）。选择≥25%患者所选的词汇来构成SF-MPQ。巴西版SF-MPQ由15个描述词组成（8个感觉类、5个情感类和2个评价类），采用二元模式评分（存在或不存在）。通过计算患者为感觉、情感、评价和总描述词所选的词汇得出四个疼痛评分。SF-MPQ显示出较差的内部一致性（KR-20 = 0.52），但可能可以接受，因为它在区分不同疼痛程度和机制的患者方面显示出判别效度，并且与LF-MPQ高度相关。KR-20系数较低可能是由于项目数量较少。巴西版SF-MPQ被证明是评估疼痛不同性质的有用工具。它是长表MPQ的可靠替代选项。
