Turkish translation, cross-cultural adaptation, and assessment of psychometric properties of the Ottawa sitting scale for the intensive care unit survivors

Validity and reliability of the Turkish version of the Ottawa Sitting Scale in patients with acute stroke

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.IMPLICATIONS FOR REHABILITATIONIndependent 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.

Clinimetric properties of the Turkish version of the De-Morton Mobility Index (DEMMI) in intensive care unit survivors - a cross-sectional observational study

PURPOSE

To investigate the intra-rater reliability and the construct validity of the Turkish version of the De-Morton Mobility Index (DEMMI) in intensive care unit (ICU) survivors.

METHODS

Construct validity of the DEMMI was measured by correlating it with physical functioning scales. Known group comparison was made according to the Medical Research Council Sum Score (MRC-SS). Internal consistency was determined by measuring Cronbach α coefficient. Test-retest reliability was assessed by performing the DEMMI by the same researcher after 24 h and calculating the intraclass correlation coefficient (ICC). The minimal detectable change (MDC) value was calculated.

RESULTS

One hundred and two patients discharged from the ICU were included. The ICC for intra-reliability was 0.972. The internal consistency was excellent (Cronbach = 0.991). The DEMMI total score was correlated with the Barthel Index (r = 0.791), Katz Index of Independence in Activities of Daily Living (r = 0.722), MRC-SS (0.614), ICU length of stay (r = -0.515), and total mechanical ventilation duration (r = -0.488). The DEMMI was able to differentiate between MRC-SS subgroups (p < 0.001), whereby higher strength was associated with higher DEMMI scores. The MDC was determined to be 6.82 out of 100 points.

CONCLUSION

The Turkish version of the DEMMI is reliable and valid for measuring mobility in ICU survivors.

TRIAL REGISTRATION NUMBER

NCT05196997Implications for RehabilitationThe Turkish version of the de-Morton Mobility Index (DEMMI) is a reliable and valid outcome measure for the assessment of functional mobility in intensive care unit survivors.The Turkish version of the DEMMI could guide clinicians working in the field of intensive care in the planning of rehabilitation programs after discharge.
