Measuring social integration in a pilot randomized controlled trial of critical time: intervention-task shifting in Latin America.

Global mental health movements increasingly highlight the importance of social integration for individuals living with severe mental illnesses. However, this important individual-level outcome is rarely measured in programs. As part of RedeAmericas, a pilot regional randomized controlled trial of critical time intervention - task shifting - will be conducted, which includes social integration as an outcome measure. It is a time-limited care coordination model to enhance continuity of support for people with severe mental illness during critical periods of transition. Given the challenges of measuring social integration, particularly for a multi-country study with unique cultural contexts, this paper has described the measurement approach used to create a composite measure that uses items from disability and quality of life instruments in addition to other key items.
