Translation, cross-cultural adaptation, and measurement properties of the Back pain knowledge and beliefs survey (BacKS) for the Brazilian population.
Article in Brazilian journal of physical therapy. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundLow back pain (LBP) is a highly prevalent and disabling health condition worldwide. A Patient-Reported Outcome Measure (PROM) to assess people's knowledge and beliefs about LBP was recently developed in Australia, but a Brazilian-Portuguese translation is not yet available. The lack of adequate cross-cultural adaptation of questionnaires is a barrier to developing LBP research and clinical practice in different cultures.
objectiveTo translate, cross-culturally adapt, and test the measurement properties of the Back pain Knowledge and beliefs Survey (BacKS) to allow its use with Portuguese-speaking Brazilians with LBP (BacKS-BR).
methodsA forward and backward translation was performed, and measurement properties of the BacKS-BR were assessed following the COSMIN guidelines. Pilot testing was performed to assess content validity and online surveys were undertaken to assess other measurement properties. Structural validity was evaluated by confirmatory factor analysis (CFA) and cross-cultural validity by multigroup CFA. Construct validity was assessed by correlation between BacKS-BR and the Back Beliefs Questionnaire and a positive moderate correlation was expected. Internal consistency was assessed by Cronbach's alpha, reliability by intra-class correlation coefficient, and measurement error by calculating the smallest detectable change (SDC).
resultsBacKS-BR had good content validity and the 2-factors structure was confirmed. Multigroup CFA produced acceptable measurement invariance. Pearson test confirmed our construct validity hypothesis (0.59). Internal consistency and reliability were adequate (>0.70) and SDC was 11.09 for total scale.
conclusionThe BacKS was successfully translated into Brazilian-Portuguese and proved to have adequate measurement properties. Its use is recommended for research and clinical purposes.
