Measuring disability among migrants with Washington Group tools. Reflections for field use

Measuring disability among migrants is a significant challenge; however, there is no consensus on how to measure disability and functional limitations. The present study reports a methodological approach to measure disability in refugees and asylum seekers using Washington Group (WG) tools, namely the WG Short Set (WG-SS), the Short Set Enhanced (WG-SS-E), and the Extended Set on Functioning (WG-ES). We interviewed 161 migrants in different regions of Italy. The recommended threshold for each WG tool was used. We identified 13.7% of migrants with disabilities using the WG-SS, 21.7% using the WG-SS-E, and 31.6% using the WG-ES. Anxiety and depression were the main weights to identify migrants with disabilities (11.8%). The WG-SS does not measure mental health, and therefore we do not suggest its use in the field. However, the WG- SS-E, together with some questions on pain and fatigue, should be considered to identify migrants with a greater risk of disability.
