WESTCHESTER, Ill. – Poor sleep quality and insomnia are significantly associated with suicidal symptoms among college undergraduates, according to a research abstract that will be presented on Monday at SLEEP 2008, the 22nd Annual Meeting of the Associated Professional Sleep Societies (APSS).
The study, authored by Rebecca A. Bernert, of Florida State University, focused on 322 college undergraduates between 19-24 years of age. The following symptom measures were administered: Pittsburgh Sleep Quality Index (PSQI); Insomnia Severity Index (ISI); Beck Depression Inventory (BDI); and Beck Scale for Suicide Ideation (BSS).
According to the results, consistent with past research, PSQI and ISI total scores were significantly associated with greater BDI scores. Elevated scores on the BSS were significantly predicted by higher scores on the ISI and the PSQI, although the latter emerged only as a non-significant trend. Importantly, after BDI scores were entered into the model as a co-variate, ISI and PSQI scores jointly predicted greater BSS scores, though they failed to significantly predict these symptoms independently.
“This investigation attempted to clarify whether self-reported sleep disturbances serve as a risk factor for suicide ideation in a nonclinical sample of young adults,” said Bernert. “We found that insomnia and poor sleep quality jointly predicted elevated suicidal symptoms, even after controlling for depression. However, these sleep complaints failed to individually predict increased risk for suicide. This suggests that, within a less severe sample, multiple indices of sleep disturbances may be necessary to assess suicide risk and guide clinical decision-making. These findings may inform both intervention efforts and suicide risk assessment models.”
Insomnia is a classification of sleep disorders in which a person has trouble falling asleep, staying asleep or waking up too early. It is the most commonly reported sleep disorder. About 30 percent of adults have symptoms of insomnia.
It is recommended that adults get between seven and eight hours of nightly sleep.
The American Academy of Sleep Medicine (AASM) offers the following tips on how to get a good night’s sleep:
  • Follow a consistent bedtime routine.
  • Establish a relaxing setting at bedtime.
  • Get a full night’s sleep every night.
  • Avoid foods or drinks that contain caffeine, as well as any medicine that has a stimulant, prior to bedtime.
  • Do not stay up all hours of the night to “cram” for an exam, do homework, etc. If after-school activities are proving to be too time-consuming, consider cutting back on these activities.
  • Keep computers and TVs out of the bedroom.
  • Do not go to bed hungry, but don’t eat a big meal before bedtime either.
  • Avoid any rigorous exercise within six hours of your bedtime.
  • Make your bedroom quiet, dark and a little bit cool.
  • Get up at the same time every morning.
“Individuals experiencing current thoughts of suicide should contact their physician or emergency mental health services,” warned Bernert. “The National Suicide Prevention Lifeline is available to anyone in suicidal crisis, offering 24-hour, toll-free suicide prevention services. If you, or someone you know, need help, please dial 1-800-273-TALK (8255).”
Those who suspect that they might be suffering from insomnia, or another sleep disorder, are encouraged to consult with their primary care physician or a sleep specialist.

The annual SLEEP meeting brings together an international body of 5,000 leading researchers and clinicians in the field of sleep medicine to present and discuss new findings and medical developments related to sleep and sleep disorders.
More than 1,150 research abstracts will be presented at the SLEEP meeting, a joint venture of the AASM and the Sleep Research Society. The three-and-a-half-day scientific meeting will bring to light new findings that enhance the understanding of the processes of sleep and aid the diagnosis and treatment of sleep disorders such as insomnia, narcolepsy and sleep apnea.
SleepEducation.com, a patient education Web site created by the AASM, provides information about various sleep disorders, the forms of treatment available, recent news on the topic of sleep, sleep studies that have been conducted and a listing of sleep facilities.
