Patients with primary insomnia often catastrophize about not sleeping, which worsens their sleep disturbance. This study found insomnia patients experienced more negative emotions when worrying about sleeplessness.

Area of Science:

  • Psychology
  • Sleep Medicine
  • Cognitive Behavioral Therapy

Background:

  • Primary insomnia is a prevalent sleep disorder.
  • Catastrophic thinking about sleep may maintain insomnia.
  • Understanding this cognitive bias is crucial for treatment.

Purpose of the Study:

  • To empirically test if catastrophic worry about not sleeping is common in primary insomnia.
  • To investigate the association between catastrophizing, negative affect, and threat perception in insomnia.

Main Methods:

  • A 'catastrophizing interview' was conducted with 30 primary insomnia patients and 30 good sleepers.
  • Participants rated the likelihood and severity of negative sleep-related consequences.
  • Emotional responses (anxiety, discomfort) were assessed during the interview.

Main Results:

  • Insomnia patients generated significantly more sleep-related catastrophes and higher likelihood ratings than good sleepers.
  • Catastrophizing was positively associated with increased anxiety and discomfort in the insomnia group.
  • No significant associations were found for the good sleeper group.

Conclusions:

  • Catastrophic worry about sleep is a common feature of primary insomnia.
  • This cognitive pattern contributes to the maintenance of sleep disturbance and associated distress.
  • Findings support cognitive restructuring techniques in insomnia treatment.
