INTRODUCTION: Sleep health is “a multidimensional pattern of sleep-wakefulness,
adapted to individual, social, and environmental demands, that promotes physical
and mental well-being”. The RU-SATED is a short practical self-reported symptom
scale that is a reliable valid tool for the rapid evaluation of sleep health.
This study sought to examine the psychometric validity of the French version.
METHODS: We conducted an observational cross-sectional study. All professionals
working in Bordeaux University Hospital were asked to answer an internet-based
questionnaire assessing sleep, mental and physical health outcomes. Sleep health
was measured using the French RU-SATED scale obtained by a rigorous reverse
translation process. Psychometric validity included factor structure, internal
structural validity, concurrent validity and external validity of the measure,
with sleep, mental and physical health outcomes.
RESULTS: A total of 1,562 participants were included with 80.5% of women and a
mean age of 40.0 (±11.2). Sleep health was within the average range (M = 8.2,
SD = 2.4) on the RU-SATED. Confirmatory factor analyses showed acceptable model
fit measures. Cronbach’s alpha coefficient was 0.57 and ranged from 0.46 to 0.58
when removing each item. The correlation between items with the overall
corrected scores ranged from 0.19 to 0.43. The “Efficiency” item showed poor
psychometric properties. Most items were highly correlated with their
appropriate sleep outcome. All items showed a strong association with positive
mental and physical health outcomes.
DISCUSSION: The French RU-SATED scale is a reliable valid tool for measuring
sleep health in adults. Nevertheless, future studies should better evaluate the
reliability and validity of the “Efficiency” item. It is also important to
explore how the RU-SATED can be used to evaluate the impact of sleep hygiene
strategies in promoting public health in accordance with models of sleep
behavior change.
