Abstract

To translate and cross-culturally adapt the Functional Status Score for the Intensive Care Unit instrument to Turkish and investigate its psychometric properties. An expert committee supervised forward and backward translation. Thirteen participants reviewed the pre-final version of Turkish Functional Status Score for the Intensive Care Unit instrument providing minor revisions to improve its readability. Two physiotherapists assessed patients (N = 50) from a coronary intensive care unit using the Turkish Functional Status Score for the Intensive Care Unit instrument. Internal consistency was excellent (Cronbach's α = 0.949). Inter-rater reliability and intra-rater reliability were excellent for each of five functional tasks and total scores (intra-class correlation coefficient = 0.955-0.996). The Turkish Functional Status Score for the Intensive Care Unit score had moderate to high correlations with other functional measures as follows: Perme Intensive Care Unit Mobility Score (Spearman's r = 0.92), Katz Activities of Daily Living (r = 0.80), handgrip strength (r =  0.76-0.77), and knee extension strength (r = 0.70-0.71). The Functional Status Score for the Intensive Care Unit instrument was translated and culturally adapted to Turkish and demonstrated strong psychometric properties, including internal consistency, intra-rater and inter-rater reliability, construct validity, and floor and ceiling effects. Implications for rehabilitation Rehabilitation professionals strive to assess and document patient status using validated and reliable outcome measures as part of good clinical practice. Longitudinal evaluation of physical function in the intensive care units is important. The Functional Status Score for the Intensive Care Unit is a validated and reliable physical functioning measurement instrument suitable for the intensive care units. The Functional Status Score for the Intensive Care Unit was translated and culturally adapted to Turkish, and demonstrated strong psychometric properties, including internal consistency, intra-rater reliability, inter-rater reliability, construct validity, and floor and ceiling effects.
