Background: Hyperarousal is one of the main pathological mechanism in chronic insomnia. The aim of current study was to comparing biological & psychological hyperarousal in response to cognitive behavior therapy (with or without metacognitive techniques) in insomnia patients.
Material & Method: After taking diagnostic assessment and checking inclusive and exclusive criteria, four patients (1 male; age 21-34), allocated to two condition, cognitive behavior therapy (CBT) & cognitive behavior therapy with metacognitive techniques (CBT+). All of patients assessed six times by indirect calorimeter, pre-sleep arousal scale, & sleep efficiency (SE). To analyzing of data, researchers utilize clinical significant (recovery percent), effect size, and diagnostic recovery.
Results: In initial sessions (session 1 to 3), observed a little compatibility between biological and psychological hyperarousal. As sessions of CBT or CBT+ proceed, compatibility between biological and psychological hyperarousal increased. In addition, in post-treatment & 3 month follow-up, both interventions decreased hyperarousal significantly. Effect sizes were between 0.74 to 1.93. Furthermore, sleep efficiency of all patients in post-treatment & 3-month follow-up, was between 89 to 94 & 88 to 90 respectively.
Conclusion: Unlike few initial sessions, compatibility between biological and psychological hyperarousal increased at post-treatment and 3-month follow-up. Both treatments decreased hyperarousal and increased sleep efficiency significantly. 
Keywords: insomnia, hyperarousal, cognitive behavior therapy, metacognitive techniques, response to treatment, sleep efficiency.
