Cross-cultural adaptation, validation, and the reliability of the Sleep-Related Behaviors Questionnaire in patients with multiple sclerosis.

PURPOSE

Examining sleep-related behavioral disorder strategies in detail for MS patients provides an essential assessment to address specific disease findings. The aim of the study was to demonstrate the reliability and validity of the Turkish Sleep-Related Behaviors Questionnaire in patients with multiple sclerosis (MS).

METHODS

A total of 100 MS patients were filled Sleep-Related Behaviors Questionnaire (SRBQ), Beck Depression Inventory (BDI), Insomnia Severity Index (ISI), and Pittsburgh Sleep Quality Index (PSQI). One week later, 30 randomly selected patients were refilled the SRBQ. The test-retest reliability, internal consistency, and contruct validity were determined.

RESULTS

The mean age of the individuals included in the study was 38.9 ± 11.0 years. The ICC value of the reproducibility of SRBQ was calculated as 0.877 (CI: 0.74-0.94). The test-retest reliability of the SRBQ was excellent (ICC > 0.80). Cronbach's alpha value of the SRBQ was 0.877, which indicates excellent consistency. The SRBQ had correlation coefficients of 0.573, 0.509, and 0.523 with ISI, PSQI, and BDI, respectively. The SRBQ had high validity (r > 0.50, p < 0.01).

CONCLUSION

The Turkish SRBQ was found to be valid and reliable in patients with MS. Owing to the long but comprehensive nature of the SRBQ, a low-cost detailed measurement could be obtained in clinical practice.
