ABSTRACT

Objective: To describe the metric properties of the SCOPA-sleep in a random sample of Mexican patients with Parkinson’s disease (PD) and to determine the prevalence of nocturnal disturbances and excessive diurnal sleepiness. Methods: We included 48 patients diagnosed with Parkinson’s disease treated at the Movements Disorders Clinic of the National Institute of Neurology and Neurosurgery in Mexico City. The SCOPA-sleep questionnaire was applied and demographic and clinical variables of all subjects were recorded. Results: The internal consistency by Cronbach’s alpha was adequate for the whole instrument (alpha = 0.87) as well as for the nocturnal symptoms and daytime sleepiness subscales (in both, alpha = 0.90). Seventy-five percent of the sample had at least one sleep disturbance, and 37.5% (n = 18) presented both nocturnal sleep disruption and excessive daytime sleepiness. Conclusion: The SCOPAsleep scale applied in Mexican PD patients possesses adequate properties that are comparable with other populations. The frequency of nocturnal symptoms and excessive daytime sleepiness was higher in our sample in comparison to the prevalence reported in other countries, which warrants further study.
