Validity and Reliability of the Dual-task Questionnaire

It is important to increase the independence of Multiple Sclerosis (MS) patients in activities of daily living. Almost all activities of daily living require managing many activities at the same time. For example, walking or standing while talking on the phone. There is a need for easily applicable, reliable and valid scales to evaluate dual-task performance in MS patients. Therefore, the aim of this study is to establish the Turkish cultural adaptation, validity and reliability of the Dual-Task Questionnaire scale in MS patients. This study included a total of 50 patients with MS [age (18-65) years]. Dual-task Questionnaire (DTQ), Timed Up and Go test (TUG) with dual-task and Nine Hole Peg test (9-HPT) with dual-task were applied to the patients. The second evaluation (retest) was carried out by the same physiotherapist one week following the first evaluation (test) in order to measure test-retest reliability.
