Mission
The Stanford Sleep and Circadian Health Clinic aims to improve sleep health through delivery of behavioral sleep medicine clinical services, provision of training and education, advancement of clinical research and scholarship, and promotion of sleep health equity.
Vision Statements
- Set a standard of behavioral sleep medicine practice grounded in evidence-based clinical care, with consideration of social, cultural, and environmental factors impacting sleep health.
- Foster competency, self-efficacy, enthusiasm, and advocacy in future sleep / health psychologists.
- Increase accessibility of behavioral sleep medicine services to advance sleep health equity.
- Encourage research, scholarship, and innovation to improve patient care and clinical outcomes.
- Educate and empower the public and communities to improve sleep health through provision of behavioral sleep medicine knowledge and tools.
- Cultivate collaboration and connection within and across disciplines to transform sleep healthcare.
Patient Care
As one of the longest established and best-known centers for sleep disorders in the country, Stanford Sleep Medicine Center sees a high volume of patients with a wide variety of sleep disorders in the context of medical and psychiatric comorbidities. Fellows are trained in the assessment, diagnosis, and treatment of insomnia, circadian rhythm disorders, nightmares, hypersomnia, parasomnias, sleep apnea, restless legs, and pediatric sleep problems. Interventions include:
- Cognitive Behavioral Therapy for Insomnia (CBT-I)
- Imagery Rehearsal Therapy for nightmares (IRT)
- Mindfulness-based and Acceptance-based therapies for insomnia
- Augmentation techniques for Circadian Rhythm Disorders (melatonin and cortisol testing, bright light therapy)
- Adjustment to PAP (Positive Airway Pressure therapy) for obstructive sleep apnea
Given the high service demands of a busy clinic, treatment follows a stepped-care model that includes individual and group formats, as well as self-management options. Fellows see individual patients but also observe and/or co-facilitate one or more of the four different groups currently offered to patients. Patients are mostly adults (ages 18-75+) but include some children (ages 7-17). Lifespan developmental issues are actively discussed to help fellows recognize unique challenges in different age groups and cohorts. Length of treatment typically ranges from 2 to 8 sessions, with a modal number of 5 sessions.
Recognizing the importance of individually tailored treatment, this fellowship emphasizes training in case conceptualization and integration of evidence-based interventions to address the complex needs of individuals with sleep problems and medical or psychiatric comorbidities (e.g., anxiety, depression, trauma, chronic pain or fatigue, cancer, concussion, POTS, or IBS). Fellows continue to refine skills in motivational interviewing and interpersonal processes to promote treatment adherence and facilitate behavioral and cognitive changes.
As fellows work with a diverse patient population, relevant aspects of cultural identity and background are included in assessment, case conceptualization and treatment. Fellows are encouraged to adapt treatment flexibly and to actively reflect on how their own background and worldview might impact treatment. Throughout this fellowship, they will gain expertise in addressing sleep concerns while considering medical, psychiatric, interpersonal, and cultural factors.

Consultation
Fellows provide formal and informal consultation to MD fellows at the Sleep Medicine Center. Medical residents and interns sometimes join fellows during individual patient assessment and treatment sessions. Fellows also give 4 presentations during the year and can co-present lectures given to other Stanford departments with Dr. Barwick, Dr. Molzof or Dr. Tingey. Fellows have the opportunity to give educational talks and do community outreach for Stanford Sleep Medicine Center’s monthly AWAKE meeting, the Pain Science Lecture Series, or the BeWell seminars.
The Behavioral Sleep Medicine team has developed several groups and specialty clinics to address insomnia with and without comorbidities as well as circadian rhythm disorders and PAP therapy for sleep apnea. Below is a brief description of the groups and specialty clinics currently offered.
Groups
Sleep Well, Be Well (SWBW): a 4-session biweekly group facilitated by sleep psychologists that offers Cognitive Behavioral Therapy for Insomnia (CBT-I) to adults with insomnia, who sometimes have mild medical and / or psychiatric comorbidities. The group replaces unhelpful thoughts and behaviors that interfere with sleep with more sleep supportive beliefs and routines, helping patients improve sleep and, if needed, de-taper sleep aids.
Ready to Improve Sleep and Energy Using PAP (RISE-UP): a 4-session biweekly group co-facilitated by a sleep psychologist and sleep technologist that combines CBT-I techniques to promote successful adjustment to PAP therapy and active problem solving of common PAP-related difficulties.
AM:PM: Sleep Health: a 7-session weekly group facilitated by sleep psychologists that integrates CBT-I with Acceptance and Commitment Therapy (ACT) for individuals who have insomnia in the context of chronic medical and / or psychiatric conditions (e.g., notable anxiety or depression, chronic pain). Techniques that are taught help participants improve sleep and daytime wellness while learning skills to navigate challenging thoughts and emotions.
All About Sleep and Pain (ASAP): a 6-session weekly group co-facilitated by sleep and pain psychologists that offers an integrated CBT protocol, which teaches techniques that simultaneously address chronic insomnia and chronic pain to help participants improve sleep, manage pain more effectively, and re-engage with valued activities.
Rotations
Primary Care Behavioral Sleep Medicine: This 6-month on-site rotation embeds a psychologist within a primary care clinic for half a day to address sleep problems that arise during patient visits with Internal or Family Medicine physicians.
Specialty Clinics
Behavioral Insomnia Clinic: This clinic offers behavioral sleep medicine assessment and treatment, including CBT-I, to individuals who have insomnia with and without medical and / or psychiatric comorbidities.
Behavioral Circadian Clinic: This clinic offers circadian and behavioral sleep medicine assessment and treatment, including options for dim light melatonin onset testing, actigraphy, light therapy and low-dose melatonin, to help individuals with simple and complex circadian sleep-wake disorders.
Behavioral PAP Clinic: This clinic streamlines referrals to the RISE-UP group (see above) to expedite adjustment to PAP therapy for treatment of sleep apnea.
Behavioral Oncology Clinic: This clinic streamlines referrals for those with insomnia in the context of breast and other cancers to make behavioral sleep medicine treatment more easily accessible to this population.
Observation Opportunities
Health Psychology: Opportunities are available to shadow health psychologists in Cardiology, Endocrinology, Gastroenterology and Pain Psychology to observe how they assess and treat patients in their specialty clinics.
The Sleep & Circadian Health Fellowship provides 2000 hours of supervised training in behavioral sleep medicine and circadian biology for full-time postdoctoral fellows during a 12-month period starting in September and ending in August.
Supervision
Supervision during the fellowship year follows a sequential developmental model and meets or exceeds the hours required for national and state licensure. During the first month, fellows observe Dr. Barwick, Dr. Molzof and Dr. Tingey conducting evaluation and treatment sessions. They also have the opportunity to observe sleep physicians and nurses in specialty clinics (e.g., narcolepsy, parasomnias, circadian, oncology), as well as sleep technologists. In subsequent months, fellows see patients individually but consult with supervisors on new patient encounters, with autonomy increasing over the course of the training year. Fellows also co-facilitate groups with Dr. Barwick, Dr. Molzof or Dr. Tingey. In addition to CBT-I groups that run throughout the year, there are also groups focused on CBT for sleep and pain, Mindfulness-Acceptance, and PAP Adjustment. Fellows may have the opportunity to develop additional behavioral sleep medicine groups based on their interests and expertise.
Fellows receive two or more hours of individual face-to-face supervision every Friday, one hour of supervision during group preparation on Thursday, and ad hoc supervision during the rest of the week. They also participate in supervised case consultation and group discussion with Behavioral Sleep Medicine (BSM) providers on Fridays.
Didactics
Postdoctoral fellows participate in didactic programs throughout the week, including Sleep Medicine and Behavioral Sleep Medicine didactics on Fridays (2-4 hours) and Psychiatry Professional Development Seminars on Tuesdays (2-3 hours). All sleep didactics offer both breadth and depth of coverage on sleep-related issues, including sleep health across the lifespan, sleep health disparities, sleep genetics and physiology, chronobiology, insomnia, circadian rhythm disorders, hypersomnia, nightmares, parasomnias, sleep-related breathing disorders, sleep-wake pharmacology, and sleep in the context of medical and psychiatric disorders. A monthly Behavioral Medicine Case Consultation group with psychologists from Cardiology, Endocrinology, Gastrointestinal and Pain clinics offers additional opportunities for broader education across specialty areas in Health Psychology.
Professional Development
Fellows participate in weekly professional development and ethics seminars as part of the Clinical Psychology Fellowship. During individual and group supervision, topics relevant to professional development are also discussed, such as psychology licensure, job search and negotiations, transition to early career, models of supervision, and work-life integration. Fellowship is structured to facilitate studying and sitting for the national licensure exam (EPPP) and well as a state licensing exam (e.g., CPLEE) and to provide strong support for job interviewing and negotiations.
Research
Although this is a clinical fellowship, research involvement is encouraged. Opportunities to peer review manuscripts and participate in ongoing research projects are available. For example, the Behavioral Sleep Medicine (BSM) program is currently overseeing a randomized controlled trial comparing two online CBT-I programs. The program is also building a database of past and current patient records in REDCap, a secure, encrypted database software management program, that can be used for querying issues related to patient care and for generating research projects that can be conducted during the year. In addition, the Division of Sleep Medicine oversees multiple ongoing research studies conducted on site and at affiliated locations.
Quality Improvement
The Stanford Sleep Medicine Division conducts 2-5 quality improvement projects yearly, and fellows are encouraged to participate. The BSM program also develops its own projects designed to improve access, efficiency and quality of patient care, to which fellows have contributed in the past.
Diversity and Multicultural Competence
Reflecting the Bay area, Stanford Sleep Medicine Center serves a diverse patient population, including but not limited to diversity in gender, age, culture, race, ethnicity, religion, disability, sexual orientation and gender identity.
The Sleep & Circadian Health Program emphasizes training in multicultural competence in the context of behavioral sleep medicine. In supervision, fellows are encouraged to actively reflect on how their cultural backgrounds and experiences shape their attitudes, beliefs, biases and privileges (or lack thereof) and how this might impact patient care. Supervision also includes discussion of intersectional identities and systemic issues that might contribute to patient health disparities and individual suffering. Finally, fellows participate in a Diversity and Inclusion Seminar as part of the Clinical Psychology Fellowship for additional training in multicultural competence.
The Sleep & Circadian Health Program values working with fellows from diverse backgrounds and strives to promote a respectful and supportive professional environment. Recognizing the importance of representation in health care, candidates from different and/or under-represented backgrounds are encouraged to apply to this fellowship.
