Survivors of torture experience numerous psychosocial stressors that threaten individual well-being in resettlement. This study reports findings from a pilot test that applied the newly developed Survivors of Torture Psychosocial Well-Being Index. The study used a case-level mixed design to assess survivor psychosocial well-being across 16 life domains from intake up to 18 months. Ecological systems theory grounds this study. Participants demonstrated increased well-being as evidenced by statistically significant change on the mean ratings of their total scores. Three case examples illustrate the instrument. Practice applications, lessons learned, study limitations, and future directions are presented.
