Assessment of psychometric properties, cross-cultural adaptation, and translation of the Turkish version of the ICU mobility scale

Abstract

Background/aim: To carry out the cultural adaptation and translation the ICU Mobility Scale (IMS) into Turkish and research the psychometric properties. Materials and methods: This study was methodological design. The IMS was translated from English to the Turkish language in a regularised translation process. Two physiotherapists assessed patients independently in coronary intensive care unit. It was assessed that construct validity, intra-rater and inter-rater reliability, and internal consistency of the IMS Turkish version. Results: A total of 70 intensive care patients were included in the study. The intra-rater and inter-rater reliability of the IMS was excellent. The weighted Kappa value was 0.92 (0.87-0.96) for the intra-rater reliability, and 0.87 (0.80-0.93) for the inter-rater reliability. There was a significant correlations between the IMS and Functional Status Score for the Intensive Care Unit (r=0.83), Perme Intensive Care Unit Mobility Score (r=0.84), Katz Activities of Daily Living (r=0.73), handgrip strength (r=0.62), knee extension strength (r=0.46) and age (r=-0.44). Conclusions: This study suggests the IMS Turkish version is reliable and valid scale for assessing functional status and mobility level in ICU patients.
