Purpose To investigate the validity and reliability of the Turkish version of the Ottawa Sitting
Scale (OSS-T) in patients with acute stroke. Materials and methods The Berg Balance Scale
(BBS) and Trunk Impairment Scale (TIS) were used to determine the validity of the OSS-T.
The OSS-T was re-applied by the same rater after an interval of 7 days to determine the
reliability. To test inter-rater reliability, the evaluation was repeated by a second rater 1 day
after the first evaluation. Reliability was quantified using intraclass correlation coefficients …

Purpose
To investigate the validity and reliability of the Turkish version of the Ottawa Sitting Scale (OSS-T) in patients with acute stroke.
Materials and methods
The Berg Balance Scale (BBS) and Trunk Impairment Scale (TIS) were used to determine the validity of the OSS-T. The OSS-T was re-applied by the same rater after an interval of 7 days to determine the reliability. To test inter-rater reliability, the evaluation was repeated by a second rater 1 day after the first evaluation. Reliability was quantified using intraclass correlation coefficients (ICC), and validity was assessed by correlating the OSS-T scores with the results of the other measures.
Results
The ICC of the total OSS-T score for inter-rater reliability was 0.996 and for intra-rater reliability, it was 0.951. The Cronbach’s α coefficient used to determine internal consistency was 0.980, which indicates excellent reliability. A strong positive correlation was found between OSS-T and TIS (rho = 0.861, p < 0.001), and between OSS-T and BBS (rho = 0.875, p < 0.001). An evident 2-factor structure was shown by the results of the factor analysis.
Conclusions
The results of this study indicated that the OSS-T has strong measurement properties, making it a valid and reliable tool for research and clinical practice in patients with acute stroke.
- Independent sitting function is an important indicator of functional recovery and discharge from hospital.
- Unlike other sitting balance tools, the Ottawa Sitting Scale can even categorize patients with low balance reserve by applying all the items with and without foot support.
- The Turkish version of the Ottawa Sitting Scale is a valid and reliable tool to evaluate sitting balance in patients with acute stroke.
