Assessing Sleep-Related Safety Behaviors: Adaptation and Validation of a French Version of the Sleep-Related Behaviors Questionnaire in a Nonclinical Sample
Résumé
Objective/Background: Safety behaviors play a prominent role in the devel-
opment and maintenance of insomnia. The Sleep-Related Behaviors
Questionnaire (SRBQ) is a self-report questionnaire designed to assess
safety behaviors employed to cope with fatigue or to improve sleep.
Despite its frequent use in insomnia, no systematic psychometric validation
of the SRBQ has been conducted; its factor structure has never been
explored. Furthermore, there is no French version of this scale. The goal
of this study was to empirically validate a French version of the SRBQ.
Participants/Methods: A total of 539 French-speaking community-dwelling
participants from the general population completed a face-to-face clinical
interview to determine insomnia disorder against DSM-5 criteria and several
questionnaires including the French SRBQ. Results: SRBQ items with poor
psychometric properties were removed, thus leading to a 20-item version
(SRBQ-20). Exploratory factor analysis and parallel analysis revealed three
distinct factors with good internal consistency. The results supported the
internal temporal stability of the SRBQ-20. The construct validity of that
instrument was underpinned by correlations obtained with various mea-
sures of insomnia and related constructs. Adequate discriminative validity
was established by comparing individuals with insomnia and individuals
without insomnia. Conclusions: This study demonstrated that
