PURPOSE: To validate a new obesity-specific disability assessment test: the
Obesity-related Disability test (Test SIO Disabilita Obesita Correlata, TSD-OC).
METHODS: Adult obese individuals were assessed with the TSD-OC, 36-Item
Short-Form Health Survey
(SF-36), 6-min walking test (6MWT) and grip strength.
The TSD-OC is composed of 36 items divided into seven sections (pain, stiffness,
activities of daily living and indoor mobility, housework, outdoor activities,
occupational activities and social life). Statistical correlations between the
TSD-OC, functional assessment (6MWT and grip strength) and quality of life
parameters (SF-36) were analysed. Internal consistency was assessed with
Cronbach's alpha test. Test-retest reliability was evaluated in a subgroup of 30
individuals. A linking exercise between TSD-OC items and categories of the
International Classification of Functioning, Disability and Health was performed.
RESULTS: Test-retest showed excellent stability (r = 0.90) and excellent internal
consistency was reported (Cronbach's alpha > 0.90). Significant low to moderate
correlations between TSD-OC, SF-36 scores, 6MWT and grip strength were observed.
A total of 26 ICF categories were linked, mostly related to the area of mobility.
CONCLUSIONS: The TSD-OC is a reliable and valid instrument for measuring
self-reported disability in obese subjects. It may represent an important tool
for establishing rehabilitation needs in individuals with obesity-related
disability, for planning appropriate rehabilitation programmes and for evaluating
their effectiveness.
