Assessing Sleep-Related Safety Behaviors: Adaptation and Validation of a French Version of the Sleep-Related Behaviors Questionnaire in a Nonclinical Sample.

Objective/Background: Safety behaviors play a prominent role in the development 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 measures of insomnia and related constructs. Adequate discriminative validity was established by comparing individuals with insomnia and individuals without insomnia. Conclusions: This study demonstrated that the French version of the SRBQ-20 has good psychometric properties.
