Objective: The current study explored the influences of the association between insomnia and stressful events on the state or trait anger in community-dwelling adults.
Methods: In total, 175 community-dwelling adults (101 females and 74 males, mean age, 41.30±8.45 years) were recruited. All participants completed a self-reported questionnaire to assess insomnia and the Korean version of the State-Trait Anger Expression Inventory. Stressful life events during the last 6 months were also assessed in face to face interviews. Participants were divided into four groups based on the presence or absence of insomnia or recent stressful life events.
Results: State anger (S-Anger), trait anger (TAnger), anger temperament (T-Anger/T), and anger reaction (T-Anger/R) differed significantly among the four groups according to insomnia and stressful events. Among normal sleepers, those with stressors showed higher T-Anger and T-Anger/R scores than those without stressors. Among those who experienced stressful life events, the S-Anger scores were higher in those with than in those without insomnia. Subjects who experienced insomnia after stressful events exhibited higher scores in all anger categories compared to normal sleepers without stressful events.
Conclusion: The present study provides support for an association between sleep reactivity after stressors and the anger. Stress-related insomnia is associated with state and trait anger in community-dwelling adults.
