The aim of the present study was to investigate the psychometric properties and validate the Portuguese version of the Fear Avoidance Beliefs Questionnaire (FABQ-Brazil). This instrument assesses how beliefs and fear of individuals with lower back pain affect two subscales related to their physical activities (FABQ-Phys) and work (FABQ-Work). The questionnaire was translated into Brazilian Portuguese, following the recommended methodology, and applied to 53 individuals with non-specific chronic lower back pain. The test-retest intra-class correlation coefficients (ICC = 0.84 and 0.91) and the internal consistency (Cronbach's = 0.80 and 0.90) for FABQ-Phys and FABQ-Work, respectively, were acceptable. The stepwise multiple regression analyses revealed statistically significant correlations between all isolated items with their respective subscales, and the set of the items explained 99% of the changes in scores for each subscale. No significant correlations were found between the subscales; however, both the FABQ-Phys and FABQ-Work subscales were positively associated with pain intensity (visual numerical scale) and degree of disability (Roland Morris Questionnaire). These findings supported the evidence that the FABQ-Brazil showed adequate psychometric properties for individuals with chronic lower back pain.
本研究的目的是调查恐惧回避信念问卷（FABQ-巴西版）的心理测量特性并验证其葡萄牙语版本。该工具评估下背痛患者的信念和恐惧如何影响与他们的身体活动（FABQ-身体）和工作（FABQ-工作）相关的两个子量表。问卷按照推荐方法翻译成巴西葡萄牙语，并应用于53名非特异性慢性下背痛患者。FABQ-身体和FABQ-工作的重测组内相关系数（ICC分别为0.84和0.91）以及内部一致性（克朗巴赫系数分别为0.80和0.90）是可以接受的。逐步多元回归分析显示，所有单个项目与其各自子量表之间存在统计学上的显著相关性，并且这些项目集解释了每个子量表得分变化的99%。子量表之间未发现显著相关性；然而，FABQ-身体和FABQ-工作子量表均与疼痛强度（视觉数字量表）和残疾程度（罗兰·莫里斯问卷）呈正相关。这些发现支持了FABQ-巴西版对慢性下背痛患者具有足够心理测量特性的证据。
