The biopsychosocial model offers a rich framework from which to address the many factors that can affect sleep, especially when sleep problems occur in the context of psychiatric or medical disorders. Using this framework to guide case conceptualization and treatment decisions can open up new perspectives for both patient and clinician, and can expand successful outcomes beyond the treatment of the sleep disturbance itself. This presentation will explain how behavioral sleep medicine incorporates a biopsychosocial model when treating disorders like insomnia, delayed sleep phase, and sleep apnea. It will provide research studies and case examples to illustrate how this approach to treating sleep problems can lead to unexpected outcomes, including benefits to mental, emotional and physical health, and will suggest mechanistic pathways that might contribute to these outcomes.
