Abstract: Anxiety is a very prevalent phenomenon across all cultures with a high relevance for societies\nregarding disability and costs. Stress is considered as a possible cause of anxiety and it can be\ndistinguished between objective stress, like stressful life events, or subjective stress, like the stress\nlevel for certain events. Previous research demonstrated a positive relation between stress and\nanxiety symptoms. However, little is known about the underlying mechanisms of this association.\nSleep problems seemed to be a possible mediator by presenting a positive relation with stress and\nanxiety symptoms. This study aimed at replicating the findings about the relation between stress\nand anxiety symptoms, as well as testing sleep problems as possible mediator of this association. An\nonline-study with questionnaires measuring stress, sleep problems and anxiety symptoms was\nconducted and analysed with linear regression and mediation analyses for 289 participants. Results\nshowed a significant relation between stressful life events and anxiety symptoms, as well as\nbetween the stress level and anxiety symptoms. Moreover, sleep problems mediated the link\nbetween stressful life events and anxiety symptoms, as well as between the stress level and anxiety\nsymptoms. This preliminary finding about sleep problems as underlying mechanism in the link\nbetween stress and anxiety can stimulate future research for replication and this knowledge can be\nuseful in improving psychological interventions for individuals suffering from stress induced\nanxiety symptoms after further consolidation of the research results
