Translation And Cultural Adaptation Of SIO Obesity-Related Disability Test (TSD-OC) For Gujarati Population (TSD-OC-Test SIO Disabilita`Obesita` Correlata, SIO-Italian Society for Obesity)

Abstract

Background: Obesity is a health condition that, through a complex interaction of biopsychosocial and environmental factors, is associated with mobility disability. SIO Obesity-Related Disability Test (TSD-OC) is a valid instrument for measuring self-reported disability in subjects with obesity. The Questionnaire consists of 36 items distributed in 7 dimensions (pain, stiffness, functionality and autonomy in daily activities, housework, outdoor, occupational activities, and social life). The aim of the study was to translate & test the validity of the Gujarati version of the SIO Obesity-Related Disability Test. Material And Methods: The TSD-OC was translated into Gujarati from English after taking authors permission according to the guidelines using forward-backward-forward method. An expert committee of 7 members including physiotherapists and physiologists evaluated the Gujarati version. Changes suggested were made and a final draft was prepared by mutual consensus. Twenty-two subjects with obesity (BMI >?25 kg/m2) were enrolled. Each question was examined by the group of 22 subjects knowing both English and Gujarati language and analysed for content, meaning, wording, format, ease of administration and scoring. Spearman’s correlation coefficients were used to assess the strength of association between the measures of both the versions.
