Translation and cross-cultural adaptation of the Sedentary Behavior Questionnaire (SBQ) for stroke survivors

Individuals frequently report adopting a sedentary lifestyle following a stroke. The Sedentary Behavior Questionnaire (SBQ) was developed to quantify daily time spent in specific sedentary behaviors (SB), and its translation will facilitate the identification of SB in Brazilian stroke survivors.

Translate and cross-culturally adapt the SBQ questionnaire into Brazilian-Portuguese for use in stroke survivors.

This is a methodological study for the translation and cross-cultural adaptation of the questionnaire. The nine SBQ items were translated in six steps, according Beaton et al: initial translation of the questionnaire, synthesis of translations, back-translation, synthesis of back-translations, committee of experts and testing of the pre-final (with 33 stroke survivors).

No discrepancies were observed between the original and back-translated versions, demonstrating adequate semantic and conceptual equivalence. The expert committee (10 physiotherapists) adapted the item descriptions to the grammatical rules of the Portuguese language and added examples to the item descriptions to increase comprehension. Participants included for final testing presented an average of 7.4 hours of SB per day, corresponding to 30.8% of the day. While on weekends this average was 6.9 hours per day, being approximately 28.75% of the day. There was an average of 37.04 total hours of SB during the week and 13.81 total hours of SB on weekends.  .

The SBQ-Brazil was adequately translated and cross-culturally adapted into Brazilian-Portuguese, allowing its use in stroke survivors. Further research is required to validate the psychometric properties, such as reliability, and to support its broader application across diverse clinical populations in Brazil.
