Note: ISI = insomnia severity index; ISI ≥ 10 indicates positive insomnia status; Poverty = <$20,000 in annual household income CAMS-R = cognitive and affective mindfulness scale – revised, 10-item version; PSAS, Cognitive = presleep arousal scale, cognitive factor; EPDS = Edinburgh postnatal depression scale; EPDS ≥ 13 indicates positive major depression status; SOI = sleep onset insomnia symptoms, i.e., inability to fall asleep within 30 minutes at least 3 nights per week over the past month.
