Evaluation of Cultural Adaptation, Validity and Reliability of the Questionnaire of Geriatric Locomotive Function Scale - 25 Questions Download PDF

Introduction: The term of Locomotive syndrome refers to conditions under which elders may soon require nursing care because of problems of the locomotive organs. the purpose of study be to evaluate the cultural adaptation, validity and reliability of the 25-question Geriatric Locomotive Function (GLFS-25), for early manifestation of locomotive syndrome. Materials and Methods: The present research is a methodological. The translation and cultural adaptation of GLFS-25 carried out by standard method of translating and equivalent, the International Quality of Life Assessment model. Face validity, Content validity, construct validity, criterion validity, internal-consistency reliability and reproducibility by test-retest reliability examined by psychometric analysis. To determine the sensitivity, specificity and cutoff point of the tool, the ROC curve used. Results: Study 1 analyzed 250 Iranian elderly ≥60 years old. Results of analysis factor for construct analysis showed that the construct structure consisted of 4 factors (pain, ability of daily activities and quality of life, social relationships, mental-psychological). For the association between the GLFS-25 and European Quality of Life Scale-5 Dimensions (EQ-5D) and VAS, Pearson׳s correlation coefficient was 0.858 and -0.722, Respectively (P = 0.01). as for Internal consistency confirmed by Cronbach׳s α reliability coefficient of 0.932. the test-retest correlation coefficient was equal to 0.96. In study 2, 70 individuals analyzed and the best sensitivity and specificity for the cut point evaluated at point 16. Conclusion: The Persian version of GLFS-25 offers as reliable and valid tool, for detecting locomotive syndrome in Iranian elderly population.
