The refugee experience is typically characterized by exposure to numerous premigration traumatic events and postmigration stress in the resettlement environment. Refugees’ experiences can lead to elevated rates of psychopathology, including posttraumatic stress disorder (PTSD) and depression. Emotion regulation is a key mechanism contributing to mental health outcomes among refugees. This study examined the impact of age on the association between emotion regulation and critical social outcomes relevant to refugee resettlement, such as social engagement and functional impairment. Participants were 1,081 Arabic‐, Farsi‐, Tamil‐ and English‐speaking adult refugees. Premigration trauma exposure, postmigration stressors, PTSD symptoms, depressive symptoms, emotion regulation, social engagement, and functional impairment were measured. A series of hierarchical regression and Poisson regression analyses revealed emotion dysregulation as a significant predictor of functional impairment, β = .36, p < .001, and social engagement, Exp B = 0.99, p = .002. A significant interaction between age and emotion dysregulation was associated with both PTSD, β = .05, p = .048 and depressive symptoms, β = .06, p = .010, suggesting a stronger positive association between emotion dysregulation and both PTSD and depressive symptom severity for older individuals. Postmigration stressor exposure, emotion dysregulation, and older age are important factors that may negatively impact social engagement and functional impairment in the resettlement environment. Additionally, higher levels of trauma exposure may negatively impact social engagement. These findings have implications for public health and social services in the context of resettled refugee communities.
