Cross-cultural adaptation and psychometric evaluation of the Greek version of the Motor Activity Log (MAL)

ΟBJECTIVE To develop the Greek version of the Motor Activity Log (MAL) and to test its reliability and internal consistency. METHOD This was a multicentre study, conducted at four rehabilitation clinics in Cyprus and Greece between 2018–2021. Translation of the MAL followed established international guidelines. The Greek MAL was completed by occupational therapists for 46 patients with hemiplegia following stroke on three occasions; days 1 and 4 by interviewing the patient and additionally, within this interval by interviewing the primary caregiver, in order to establish the degree of agreement between patient and caregiver. Internal consistency was measured using Cronbach’s alpha (α) and reliability was assessed with the use of intra-class correlation coefficient (ICC). RESULTS There were no major issues that arose during the forward-backward translation of the MAL into Greek, neither cultural adaptation conflicts. The internal consistency was high (Cronbach’s α=0.95), while the test-retest reliability was 0.993 for both MAL Amount of Use (AOU) and Quality of Use (QOU) Scale. ICC between caregivers and patients was 0.987 for MAL AOU and 0.980 for MAL QOL. CONCLUSIONS The Greek version of MAL is a reliable assessment tool for adult patients with hemiplegia following stroke. It may be considered a useful tool for the out-of-clinic measurement of upper limb involvement in everyday activities for Greek-speaking clinicians. © Athens Medical Society.
