Abstract
Objective/Background: Safety behaviors play a prominent role in the devel-opment and maintenance of insomnia. The Sleep-Related BehaviorsQuestionnaire (SRBQ) is a self-report questionnaire designed to assesssafety behaviors employed to cope with fatigue or to improve sleep.Despite its frequent use in insomnia, no systematic psychometric validationof the SRBQ has been conducted; its factor structure has never beenexplored. Furthermore, there is no French version of this scale. The goalof this study was to empirically validate a French version of the SRBQ.Participants/Methods: A total of 539 French-speaking community-dwellingparticipants from the general population completed a face-to-face clinicalinterview to determine insomnia disorder against DSM-5 criteria and severalquestionnaires including the French SRBQ. Results: SRBQ items with poorpsychometric properties were removed, thus leading to a 20-item version(SRBQ-20). Exploratory factor analysis and parallel analysis revealed threedistinct factors with good internal consistency. The results supported theinternal temporal stability of the SRBQ-20. The construct validity of thatinstrument was underpinned by correlations obtained with various mea-sures of insomnia and related constructs. Adequate discriminative validitywas established by comparing individuals with insomnia and individualswithout insomnia. Conclusions: This study demonstrated that
