The objective of this study was to examine psychometric properties of the Tampa Scale for Kinesiophobia, which was translated and adjusted according to recommended methodology. The adjusted version, the Escala Tampa para Cinesiofobia (ETC), was applied to 50 subjects with non-specific chronic lumbar pain (CLP). The Rasch analysis disclosed a reliability coefficient of 0.95 for ETC items, suggesting excellent construct validity. For the subjects, this coefficient was 0.80, showing a steady answer pattern. Subjects separation rates were 2.0 and 4.5 for the items, showing that patients were divided into two kinesiophobia levels, and the items were divided into five levels. Two erroneous items have been identified, showing percentages above the 5% allowed by statistical model. These results indicate a need for modification, replacement or exclusion of those items in order to assure that the instrument assesses a single-dimensional construct. On the other hand, the presence of very difficult items suggests that ETC can be administered to subjects with higher levels of kinesiophobia. These findings indicate that ECT presents a significant potential for clinical applicability in individuals with CLP; however, a careful interpretation of the results is required, especially for answers to the items regarded as erroneous.
