This brief self-report measure assesses the extent to which an individual has internalized negative stereotypes and self-stigmatizing beliefs related to having a mental illness. The Internalized Stigma of Mental Illness Scale (ISMI-9) is commonly used to support clinical formulation and research by characterizing the subjective impact of stigma on self-concept and social functioning.
The instrument includes 9 items and typically takes about 2 minutes to complete. Items are designed to capture core dimensions of internalized stigma (e.g., shame, alienation, and perceived discrimination), and results are generally interpreted as an indicator of severity to inform treatment planning and monitor change over time. The Internalized Stigma of Mental Illness Scale (ISMI-9) is attributed to David L. Penn.
