Refugees experience elevated rates of mental health problems, but little is known about mental health service utilization and quality among asylum seekers and refugees in Europe. In a 12‐month follow‐up study of newly arrived refugees (N = 166, Mage = 32.38 years, 30.7% female) and a nationwide cross‐sectional study (N = 579, Mage = 33.89 years, 36.2% female) of refugees who had been living in Germany for an average of 6 years, we examined objective need for mental health treatment, perceived need, access to treatment services, and adequacy of treatment. We defined minimally adequate mental health treatment according to the WHO World Mental Health Survey as ≥8 sessions of psychotherapy (minimally adequate psychotherapy) or pharmacotherapy plus ≥4 medical visits (minimally adequate pharmacotherapy). In both studies, two in three individuals screened for mental health symptoms and additionally perceived a need for professional treatment. Of those, less than half had contact to any service provider, with only 1 in 14 receiving minimally adequate psychotherapy. Overall, no more than one in seven of refugees in need received minimally adequate treatment. Despite a comprehensive mental health‐care system, refugees' access to mental health care and the treatment provided are inadequate. Health policies are urgently needed to provide equitable mental health care for all.
