Abstract Background Global migration and increasingly diverse populations poses new challenges to mental health services. Cultural differences between refugees and mental health professionals and lack of cultural competency is described as challenging. Cross-cultural training has been proposed as one way to reduce these problems. There are few evaluations on cross-cultural mental health training outcomes. Between 2016-2018, 13 one-day cross-cultural training interventions was implemented in Stockholm to equip mental health professionals to respond to mental health needs in a time of high influx of refugees. Objectives To evaluate a comprehensive cross-cultural training program regarding participant’s knowledge development, their experiences and views of the training - and their perceptions about their capacity to deliver mental care to refugee patients. An embedded mixed-method design was applied. We used before and after training questionnaires (n = 248) and conducted six focus group discussions (FGD) with mental health professionals. Quantitative data were analyzed by paired t-test and factor analysis, qualitative data were analyzed by thematic content analysis. Preliminary results Before the training, significant differences of mean knowledge was found (p = 0.004) among participants. Principle axis Factoring resulted in 3 factors before and 4 factors after the training, explaining 78% of the covariance. Findings from the after training FGDs, revealed that refugee patients were described as different and challenging, and little was known about the reality they live in. The training contributed to a better understanding of migration, integration and refugee health- as well as the role of culture. Further, it promoted empathy and professional self-reflections. Conclusions Cross-cultural training can contribute to knowledge development, attitude changes and also be valuable for care provider’s professional role. Key messages Training mental health professional in cross-cultural issues may facilitate improved quality of care to refugee groups. The training can also strengthen participants in their professional role.
