Reliability And Validity Of Turkish Version Of Motor Activity Log-28
Abstract
OBJECTIVE: The aim of this study was to adapt the Motor Activity Log-28 (MAL-28) into Turkish and probe the reliability and validity of this questionnaire in stroke patients. METHODS: Following the translation of the MAL-28 into Turkish, its reliability and construct validity was examined in 30 stroke patients. For the reliability study, patients were interviewed twice within a three day period, during which no rehabilitative activities were undertaken. The test-retest reliability was determined by using intra-class correlation coefficient (ICC) and Spearman correlation coefficient (r); internal consistency was determined by Cronbach's alpha (α). The construct validity was examined by comparing MAL-28 Quality Of Movement (QOM) scale and Amount Of Use (AOU) scale with Wolf Motor Function Test (WMFT)-Performance Time (PT) and Functional Ability (FA) scores. Furthermore, item-to-scale correlations of AOU and QOM scales were determined and correlation between totol scores of two scales was examined. RESULTS: Turkish version of MAL-28 AOU and QOM scales were reliable (ICC scores were 0.97 and 0.96, respectively) and internally consistent (Cronbach’s α value was 0.96 for both scales). Test-retest reliability was supported (AOU, r=0.94; QOM, r=0.93). WMFT FA scores was correlated with both scales (r=0.63). Correlation between WMFT PT and AOU and QOM scales were -0.56 and -0.55. AOU and QOM scales were highly correlated (r=0.95). CONCLUSION: The findings indicate that Turkish version of MAL-28 is reliable and valid in individuals with stroke. Further investigation about its responsiveness is needed before using that version as a primary measurement in clinical trials.
