Session Title: Restless legs syndrome and other sleep disorders
Session Time: 12:30pm-2:00pm
Location: Exhibit Hall located in Hall B, Level 2
Objective: Our aim was to modify the Restless Legs Syndrome Quality of Life (RLS-QoL) questionnaire advanced by Abetz (Health Qual Life Outcomes 3:79, 2005) and to analyse the validity and reliability of the questionnaire.
Background: Restless legs syndrome (RLS) is a movement disorder in which an individual experiences a strong urge to move the legs or other extremities while at rest; symptoms are temporarily or at least partially relieved by movement. We aimed ensure the feasibility for Turkish society by examining the validity and reliability.
Methods: Two hundred and one consecutive patients with RLS and forty-three control subjects were included in the study. Permission regarding the translation and validation of the RLS-QoL questionnaire was obtained. The translation was conducted according to the guidelines provided by the publisher.
Results: For the RLS subjects, the mean Insomnia Severity Index (ISI) score, the International Restless Legs Syndrome Severity Rating Scale (IRLSSG) score and the computed score of the RLS-QoL questionnaire were 22.60 ± 3.39, 24.83 ± 5.28 and 45.93 ± 17.62, respectively. Among the RLS subjects without insomnia, the mean (±standard deviation) ISI score, IRLSSG score and computed score of the RLS-QoL questionnaire were 6.67 ± 2.34, 15.11 ± 4.03 and 41.93 ± 16.12, respectively. A significant difference was identified between both groups on all scores (ISI: p = 0.001, RLS: p = 0.001). The groups with and without insomnia were similar regarding the computed score of the RLS-QoL questionnaire (p = 0.140). According to a correlation analysis, a significant correlation was identified between the ISI and IRLSSG or RLS-QoL scores (r = 0.513, p = 0.001 and r = -0.383, p = 0.001, respectively). Although the coefficient of correlation is significant between IRLSSG scoreand RLS-QoL scale score, it should not be considered as a powerful enough correlation (r = 0.190, p = 0.007). Most items also exhibited a strong correlation with each other. The internal consistency determined by Cronbach’s alpha indicated an extremely good correlation (0.975).
Conclusions: These findings suggest the Turkish version of the RLS-QoL questionnaire is a valid and reliable tool for the assessment of the quality of life in patients with RLS.
