Abstract Introduction: According to the diathesis-stress model of insomnia, a vulnerability to developing it may lead to insomnia in response to stress. Recently, there has been a paradigm shift in the understanding of resilience in context of stress- risk-vulnerability dimension. Resilience is a psychobiological factor which determines individual’s capacity to adapt successfully to stressful events. Lower level of resilience increases vulnerability for developing mental disorders. Beacuse emotion and arousal regulation is a key factor in insomnia the aim was to explore the level of resiliency in subjects with insomnia and its relationship with emotion and arousal regulation. Methods: The study consisted of 48 subjects with Insomnia disorder according to the DSM-5 and 35 good sleepers. Insomnia Severity Index (ISI), Resilience Scale for Adults (RSA), Difficulties in Emotion Regulation Scale (DERS), Pre-sleep Arousal Scale (PSAS) were administered while controlling for anxiety and depressive symptoms. Differences in means between groups were assessed using t-test or Mann-Whitney U/Wilcoxon test. Univariate/ multivariate regression analyses and mediation analyses were performed. Results: Subjects with Insomnia (F 24, mean age 49 ± 2.1) presented higher ISI, RSA, DERS and PSAS scores than good sleepers (F 22, mean age 47.2 ± 1.2) (ISI: 15.7 ± 5.8 vs 5.1 ± 0.6, p
