Sleep disturbance severity predicts capsule self-administration, regardless of whether the capsule contains placebo or active triazolam. Polysomnography measures effectively predicted capsule choices in individuals with varying sleep issues.

Area of Science:

  • Sleep Medicine
  • Behavioral Science

Background:

  • Sleep disturbances, including insomnia, affect a significant portion of the population.
  • Understanding factors that predict medication-seeking behavior is crucial for effective treatment.

Purpose of the Study:

  • To investigate whether polysomnography-derived sleep variables predict capsule self-administration in individuals with a wide range of sleep disturbances.
  • To determine if sleep disturbance severity influences the likelihood of choosing to take a capsule before sleep.

Main Methods:

  • Sixty-four healthy adults with and without insomnia underwent polysomnography.
  • Participants were offered placebo or triazolam (0.25 mg) capsules using a single-choice method.
  • Screening sleep measures were analyzed to predict capsule self-administration.

Main Results:

  • Individuals with persistent psychophysiologic insomnia self-administered more capsules than other groups.
  • Polysomnographic measures, particularly the ratio of stage 3-4 sleep to wake/stage 1 sleep, predicted capsule choices (R=0.44).
  • Morning mood states, including fatigue and reduced concentration, also predicted capsule choices (R=0.36).

Conclusions:

  • The degree of sleep disturbance is a significant predictor of capsule self-administration.
  • This predictive relationship holds true whether the capsule is a placebo or an active medication.
