Social Inclusion Scale (SIS)

The Social Inclusion Scale (SIS) is a brief measure assessing the degree to which individuals with serious mental illness perceive themselves as included, valued members of their community. Developed by Oades, Deane, and colleagues in 2005, the SIS captures subjective experiences of social participation, acceptance, and integration. The scale is used in recovery-oriented mental health services and research to evaluate community integration outcomes and inform interventions promoting social inclusion.
