Immigrant and refugee populations experience life stressors due to difficult migration journeys and challenges in leaving one country and adapting to another. These life stressors result in adverse mental health outcomes when coupled with a lack of adequate support-enhancing resources. One area of support is access to and use of mental health services to prevent and address mental health concerns. Immigrant service providers in Canada support the integration and overall well-being of newcomers. This study focuses on immigrant service providers' perceptions of access to and use of mental health services for immigrants and refugees in Alberta. A qualitative descriptive design was used to collect and analyse the perspectives of 53 immigrant service providers recruited from nine immigrant serving agencies in Alberta between November 2016 and January 2017. Data were collected using a combination of individual interviews and focus groups, followed by thematic data analysis to identify relevant themes. Barriers to access and use of mental health services include language barriers, cultural interpretations of mental health, stigma around mental illness, and fear of negative repercussions when living with a mental illness. Strategies to improve mental health service delivery include developing community-based services, attending to financial barriers, training immigrant service providers on mental health, enhancing collaboration across sectors in mental health service delivery, and advancing the role of interpreters and cultural brokers. Overall, immigrant service providers present a nuanced view of the complex and inter-related barriers immigrants and refugees experience and identify potential approaches to enhancing mental health service delivery.

Introduction: Data on immigrant and refugees’ access to services in Canada typically focus on adult populations generally but not children specifically. To fill this gap, this study explored immigrant and refugee mothers’ perceptions of barriers and facilitators for mental health care for their children in Edmonton, Alberta, Canada. Method: In this qualitative descriptive study, researchers conducted 18 semistructured interviews with immigrant and refugee mothers who live in Edmonton, self-identify as women, and have children living in Canada. Results: Barriers included financial strain, lack of information, racism/discrimination, language barriers, stigma, feeling isolated, and feeling unheard by service providers. Facilitators included schools offering services, personal levels of higher education, and free services. Discussion: Nurses can improve access to mental health services by addressing issues related to racism within the health system, by creating awareness related to mental health, and by providing trained interpreters to help bridge barriers in communications.

Background: Reductions in total hippocampus volume have frequently been reported in MRI studies in major depressive disorder (MDD), but reports of differences in total amygdala volume have been inconsistent. Childhood maltreatment is an important risk factor for MDD in adulthood and may affect the volume of the hippocampus and amygdala. In the present study, we examined associations between the volumes of the amygdala subnuclei and hippocampal subfields and history of childhood maltreatment in participants with MDD. Methods: We recruited 35 patients who met the DSM-IV criteria for MDD and 35 healthy controls. We acquired MRI data sets on a 4.7 T Varian Inova scanner. We manually delineated the amygdala subnuclei (lateral, basal and accessory basal nuclei, and the cortical and centromedial groups) and hippocampal subfields (cornu ammonis, subiculum and dentate gyrus) using reliable volumetric methods. We assessed childhood maltreatment using the Childhood Trauma Questionnaire in participants with MDD. Results: In participants with MDD, a history of childhood maltreatment had significant negative associations with volume in the right amygdala, anterior hippocampus and total cornu ammonis subfield bilaterally. For volumes of the amygdala subnuclei, such effects were limited to the basal, accessory basal and cortical subnuclei in the right hemisphere, but they did not survive correction for multiple comparisons. We did not find significant effects of MDD or antidepressant treatment on volumes of the amygdala subnuclei. Limitations: Our study was a crosssectional study. Conclusion: Our results provide evidence of negative associations between history of childhood maltreatment and volumes of medial temporal lobe structures in participants with MDD. This may help to identify potential mechanisms by which maltreatment leads to clinical impacts.
