Mental health problems are high among refugees due to their traumatic experiences of fleeing war and witnessing disasters and deaths due to violence and conflict. Refugees are exposed to various socio-cultural stressors during their migration journey before, during, and after arriving at the host country, which may increase their risk of mental health problems. Strength-based interventions may be beneficial to address their socio-cultural and psychological stressors by strengthening individual's strengths to address their problems. This study evaluated the effect of a Social and Emotional Wellbeing intervention on mental health (stress, anxiety, and depression) and emotional health outcomes (coping, self-efficacy, social support, and conflict resolution) among Ukrainian refugees in Massachusetts. We implemented intervention (once-weekly/5-week) among 31 Ukrainian refugees with pre-and post-assessment of mental and emotional health outcomes (2022-2023). The intervention consisted 5-module: managing stress and mind-body exercise, strengthening communication and social networking, problem-solving, and creating a healthy family environment. Validated scales were used to measure mental and emotional health outcomes, such as the Hopkins-Symptom-Checklist-25 for anxiety and depression and the Cohen-Perceived-Stress scale for stress. Paired t-test was used for data analysis. The pre versus post-intervention proportion reduced for anxiety (61.29% vs. 22.58%) and depression (58.06% vs. 22.58%). The mean scores significantly decreased from pre- to post-intervention by 6.26 points for stress, by 7.07 points for anxiety, and by 6.29 points for depression (both p's < .01). The mean scores significantly increased for coping (by 15.71), emotion-focused engagement (4.48), problem-focused engagement (4.80), social support (8.77), problem-focused coping self-efficacy (14.93), stop unpleasant emotions and thoughts (12.74), and friends networking (3.48; all p's < .01). The stress, anxiety, and depression were reduced, and coping, self-efficacy, and social support networking skills were improved among Ukrainians after intervention. This program should be replicated in the larger community for a wider benefit.
