Translation, cross-cultural adaptation and validation of the Weight Management Questionnaire in the Brazilian population: a cross-sectional study.
Article in Sao Paulo medical journal = Revista paulista de medicina, 2025. 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
backgroundThe prevalence of obesity has increased considerably worldwide, and it has become an important risk factor for chronic non-communicable diseases. BJECTIVE: To translate, cross-culturally adapt, and validate the Weight Management Questionnaire (WMQ) to evaluate weight control practices for health monitoring and intervention in Brazil. DESIGN AND
settingThis was a quantitative cross-sectional study.
methodsObese and physically active lean individuals aged 18-59 years were included in this study. The tool used as an adaptation was the WMQ. The cross-cultural adaptation was conducted in five phases. For structural validity, confirmatory factor analysis (CFA) was used to verify the internal structure considering two domains: diet and physical activity. To determine construct validity, a comparison was performed between different groups (lean versus obese). Reliability was assessed using the intraclass correlation coefficient (ICC).
resultsThe short version of the WMQ after CFA presented eight items. Thus, the structure with two domains presented adequate fit indices: chi-square/degree of freedom = 1.66, comparative fit index = 0.996, Tucker-Lewis index = 0.994, root mean square error of approximation = 0.057, and standardized root mean square residual = 0.047. For construct validity, a significant difference was observed between the groups (P < 0.05) in both domains. We observed adequate reliability for both domains (ICC ≥ 0.854).
conclusionsThe WMQ can be used for the Brazilian population, as it is reliable and has adequate internal structure, supporting its use in future research.
