The current study developed and implemented a trauma-informed psychoeducation (TIPE) intervention that is culturally relevant to urban Somali refugees in Nairobi, Kenya. A total of 141 Somali refugee youth completed 12 sessions of peerled TIPE intervention. A series of pre-and post-tests revealed that TIPE made positive impacts on PTSD symptoms and psychosocial factors, with a differential effect observed according to baseline PTSD symptom report. Participants with high baseline PTSD scores (i.e. above clinical threshold) reported a significant decrease in PTSD symptoms and increase in perceived social support. In the meantime, those with no to mild baseline PTSD symptoms showed an increase in selfawareness of trauma responses and thus PTSD symptom report within the range of normalcy. This research supports the effect of a culturally relevant psychoeducation intervention in addressing the high mental health and psychosocial needs of the marginalized urban Somali refugee community in low resource settings.

Findings underscore the importance of understanding mental health in the broader context of community adversities, suggesting development of contextually informed interventions responsive to complex needs of urban refugees.

Background: Comorbid common mental disorders (CMDs) are pervasive in refugee populations. However, limited research has explored psychosocial factors for mental disorder comorbidity in Somali refugee samples. Aims: This study aims to explore potential risk and protective factors for comorbid depression-anxiety and comorbid depression-PTSD by examining associations between trauma exposure, psychosocial factors, and mental health symptoms among a sample of Somali refugees displaced in urban Kenya. Methods: We used snowball sampling to recruit Somali youth aged 15 to 35years( N = 250, n = 143 female, n = 88 male, n = 19 unknown gender). We measured 16 common types of trauma exposure and three psychosocial factors (endorsing violence, willingness to share problems, and symptom awareness) and used the HSCL-25 and PCL-C to capture individual and comorbid CMD symptoms, using guided cutoff points and/or algorithms. We then ran a series of logistic regression analyses to examine relationships between trauma exposure, psychosocial factors, and individual and comorbid CMD symptoms. Results: Findings showed that increased trauma exposure predicted symptoms of individual and comorbid CMDs. Increased symptom awareness and endorsement of violence predicted comorbid depression-PTSD and comorbid anxiety-depression symptoms, respectively. Willingness to share problems buffered depressive symptoms but did not predict comorbidity. Conclusions: These findings revealed the high CMD comorbidity prevalence with differential effects of trauma and psychosocial factors on individual or comorbid mental disorders. This study suggests a need for transdiagnostic approaches that cut across Western diagnostic boundaries and consider culturally responsive and relevant items for mental health measures.
