Previous studies have reported high levels of symptoms of depression, anxiety and post-traumatic stress disorder (PTSD) among women survivors of human trafficking, but have been hampered by using screening scales rather than a diagnostic instrument, by including women at different stages of trafficking, and by combining populations from different ethnicities, limiting internal validity. No previous research has described risk factors for diagnosed mental disorder among women survivors of human trafficking.  The present study addresses this gap by assessing a consecutive sample of ethnic Moldovan women survivors of human trafficking assisted on return to Moldova using a diagnostic instrument to measure mental disorder.
