Abstract

De-Morton Mobility Index(DEMMI) is a scale recommended for the evaluation of mobility in the reports of experts working in the field of intensive care, and the psychometric properties of its Turkish version in these patients are unknown.Therefore, our study's aim is to examine the psychometric properties of DEMMI in the intensive care survivors.

102 patients (Median age; 63 years) discharged from the ICU were included in our study, which was conducted with a cross-sectional observational study design.For construct validity, correlation coefficients between DEMMI's Barthel Index(BI), Katz Activities of Daily Living Scale, Medical Research Council(MRC) Muscle Strength Assessment, total mechanical ventilation time, length of stay in ICU, age, and APACHE-II score were calculated.MRC muscle strength score was used for known group validity.For test-retest reliability, the scale was re-administered to the patients 24 hours later, and the intraclass correlation coefficient(ICC) and minimal detectable change value were calculated.

DEMMI total score(Median value; 30/100) was high with BI and Katz(r=0.791,r=0.722 p<0.001,respectively),MRC muscle strength value, ICU length of stay, and total mechanical ventilation time were moderate(r=0.614, p<0.001, respectively) showed a correlation.The internal consistency of the scale was found to be excellent(Cronbach ? = 0.991).The ICC value calculated for inter-measurement reliability was 0.972, and the minimal detectable change value was 6.82.

It has been seen that DEMMI is a valid and reliable scale for intensive care survivors.Further studies should focus on evaluating the responsiveness of DEMMI Turkish version scores to rehabilitation process in ICU.
