Objective:
To develop a Spanish version of the Rett Syndrome Motor Evaluation Scale (RESMES) for the locomotor function of Rett Syndrome (RTT) using a transcultural methodology.
Methods:
The RESMES was cross-culturally adaptated and validated in the Spanish language (RESMES-sp). This study was divided into two well-differentiated phases: 1) a cross-cultural translation and adaptation; 2) psychometric characteristics analysis of the RESMES-sp (reliability, test-retest, construct validity, criteria validity, error measurements). For criteria validity, PAINAD questionnaire, the scoliosis values and PedsQL™, were used.
Results:
A total of 63 girls and women diagnosed with RTT participated in this validation study. The total value of the RESMES-sp correlates significantly with all its dimensions, with the correlation value oscillating between 0.645 and 0.939. The correlation value with PAINAD ranges between 0.439 and 0.805; the scoliosis values ranges between 0.245 and 0.564; with PedsQOL™ questionnaire, the correlation values range between 0.273 and 0.663 for the PedsQL™ dimensions, and between 0.447 and 0.648 for the total value of PedsQOL™ questionnaire. The reliability values of Crombach's alpha ranged between 0.897 and 0.998 for the intra-observer analyses and between 0.904 and 0.998 for the inter-observer reliability. The SEM showed a value of 2,829, while the MDC90 showed a value of 6601. The Exploratory Factor Analysis showed 6 factors and values of variance of 86.163%.
Conclusions:
The Spanish version of the RESMES is a reliable and valid tool for the functional assessment and follow-up of patients with RTT.
