  • Proposed that psychological vulnerability interacts with stressful events to trigger sleep-interfering processes.
  • Highlighted dysfunctional sleep-interpreting processes, influenced by beliefs and standards, as contributing to insomnia.

    • Conclusions:

    • Psychological processes play a central role in the etiology and persistence of insomnia.
    • Vulnerability factors predispose individuals to maladaptive responses to stress and negative sleep interpretations.
    • Understanding these psychological mechanisms is key for developing effective insomnia treatments.
