Abstract

Introduction: Cognitive behavioral therapy for insomnia places considerable emphasis on sleep interfering behaviors in bed (stimulus control and sleep hygiene recommendations), with lesser emphasis on the actual sleep environment and its potential to disrupt sleep. We developed and tested a Sleep Environment Questionnaire (SEQ) to better understand the association between these two factors and self‐reported sleep difficulties.

The Insomnia Severity Index (ISI), Edinburgh Postnatal Depression Scale (EPDS), and SEQ were administered at baseline. Results: The ASDF total score and six out of eight individual items were significantly correlated with ISI (p's
