- •Untreated sleep disordered breathing (e.g., obstructive sleep apnea) assessed by self-report, clinical interview, and/or diagnostic sleep study (i.e., baseline sleep study PSG)
- •Failing to meet criteria for MRI scan (e.g., having metallic implants); see Pre-screen MRI Checklist for full list of exclusions for MRI scans.
- •Fear/phobia of needles (conflict with blood draw) and/or small spaces (conflict with MRI scanner)
- •Current suicide risk meriting crisis intervention as assessed by the Patient Health Questionnaire (PHQ-9) and/or disclosure of serious suicidal ideation
- •Pregnancy (self-report, proposed instruments and treatments have not been validated in this population)
- •Sleep efficiency > 85%, assessed by the sleep diary
- •Serious mental health diagnosis (e.g., bipolar disorder or psychosis) assessed by structured interview (M.I.N.I.)
- •Currently engaged in evidence-based psychotherapy for Insomnia (i.e., Cognitive Behavioral Therapy) by self-report
