The Syrian War has created a mass exodus of Syrian citizens to neighboring countries and exposed them to many atrocities. We explored factors affecting well-being and posttraumatic growth (PTG) of refugees residing in Jordan. Participants (N = 250) were surveyed via nongovernmental organizations (NGOs). Outcome criteria included a global well-being rating and the Posttraumatic Growth Inventory. Trauma exposure assessment included The Harvard Trauma Questionnaire (HTQ) and The War Events Questionnaire. Ordinary least squares regression examined associations between potential contributors to refugee well-being and PTG, including work, age, sex, income, education, posttraumatic stress disorder (PTSD) severity, physical pain, health, NGO assistance, psychotic/affective mental disorder, and length of residence in Jordan. Mean participant score on the PTSD-HTQ scale was 2.37 (SD = 0.63; range: 1 [no symptoms] to 3.88 [extremely severe symptoms]). Additionally, 74.6% of participants received NGO assistance and 92.7% experienced war events. Univariate and multivariate results indicated enhancement of well-being was associated with income, r = .34, β = .26, p < .001; health, r = .35, β = .26, p = .001; and absence of affective disorder, r = -.31, β = -.18, p = .012; and that PTG increased in association with income, r = .28, β = .20, p = .007; NGO assistance, r = .07, β = .14, p = .045; and absence of psychosis, r = -.12, β = -.17, p = .013, and affective disorder, r = -.26; β = -.16, p = .033. Findings suggest sufficient income and humanitarian assistance can contribute to Syrian refugees' mental health.
