Introduction: Suicide represents a global disease burden, accounting
for 57% of all violent deaths in the world annually. Sleep complaints are
listed among the top 10 warning signs of suicide by SAMHSA, and a
growing body of evidence suggests that self-reported insomnia and poor
sleep quality constitute modifiable risk factors for suicide. Despite these
findings, a study has yet to evaluate the impact of a sleep intervention
on suicidal ideation.
Methods: Participants (57% female) included 303 community outpatients,
aged 18-88 years (M=48) who completed group cognitive behavioral
therapy for insomnia (CBT-I). Patients were not excluded on the
basis of comorbid psychiatric, medical, or sleep disorders. The Beck
Depression Inventory (BDI) was administered at both baseline and posttreatment.
Treatment sessions were delivered weekly, with the exception
of the final two sessions (scheduled biweekly). All procedures were
HIPPAA compliant, and pre-approved by the Institutional Human Subjects
Review Board.
Results: Paired t-tests were conducted to test the hypothesis that an
open trial of CBT-I would result in posttreatment reductions in BDI
total scores and suicidal ideation. Results revealed significantly lower
BDI scores (sleep item removed) posttreatment [t(295)=12.11, p0 on the suicide ideation item (BDI item 9), CBT-I produced a statistically
significant posttreatment reduction in suicidal ideation [t(64)=9.41,
