Purpose The goal of this study was to assess the validity and reliability of the Turkish version of the Internalized Stigma of Mental Illness Scale–Adolescent Form (ISMI‐AF). Methods A total of 145 adolescents (12–18 years of age) who were diagnosed with at least one mental disorder according to DSM‐5‐TR participated in the study. Data were collected at a mental health hospital between October 2017 and 2019 using a sociodemographic information form, the ISMI‐AF, and Beliefs towards Mental Illness (BMI) Scale. Reliability (Cronbach's alpha, Split–Half, Spearman–Brown, Hotelling T 2 test) and validity analyses of the ISMI‐AF were performed. SPSS 26.0 and LISREL 8.80 software were used for statistical analyses. Results The Cronbach's alpha coefficient for total score was .88, Split–Half score was .84, and the Spearman–Brown factor score was .85. Confirmatory factor analysis showed that the scale confirmed to the five‐factor structure in adolescents, but factor loadings and reliability coefficients were low in the “stigma resistance” subscale. There was a positive and weak correlation between ISMI‐AF and BMI ( r = .37, p = .00). Conclusion The ISMI‐AF is a valid and reliable measurement tool that can be used in adolescents. This scale can help psychiatric nurses who work in this field identify and address internalized stigma, which is one of the key factors affecting adherence to treatment, especially in adolescents.
