jats:pMany refugees experience a wide range of mental health problems, but typically use mental health services less often than settled residents. Practical constraints like limited access to mental health care and language barriers largely account for this discrepancy. However, little is known about the psychological aspects explaining this difference in mental health service usage, like attitudes toward psychological help-seeking and the disclosure of distress. The present study compares German residents’ and Syrian refugees’ attitudes toward seeking professional psychological help ( N = 384). Refugees reported more depressive symptoms and functional impairment than residents. Crucially, refugees also held more negative attitudes toward professional psychological help-seeking than residents. These group differences in attitudes were to a large part mediated by distress disclosure. We conclude that it is important to achieve a thorough understanding of how to address help-seeking attitudes and to encourage distress disclosure to promote treatment of mental health issues among many refugees.</jats:p>
