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. Result: Data of 22 subjects was analysed. Fifteen Female and Seven Male with mean
age 47.9±6.8 years were taken. In validation process of Gujarati version of TSD-OC, Mean total score for
Gujarati version was 57.45±51.75 and Mean Percentage was 15.96±14.38 and English version was
55.23±54.94 and Mean Percentage was 15.34±15.26. The total score was significantly and positively
correlated (?=0.92) where p<0.001 between the TSD-OC Gujarati and original English version of TSD-OC.
Conclusion: Gujarati version of TSD-OC for disabilities in obesity has a good validity to be used in Gujarati
population. [Bhatt C Natl J Integr Res Med, 2023; 14(4):27-31, Published on Dated: 08/07/2023]
