Supplementary file 1_Development of self-stigma scale for adolescents in conflict with the law and its association with implicit self-stigma.docx

Study 1 developed and validated the Self-Stigma Scale for Adolescents in Conflict with the Law (SSS-ACL), confirming a two-factor structure comprising perceived and internalized stigma with sound psychometric properties.

Study 2 employed two IRAP protocols based on the DAARRE model to capture spontaneous relational responding for each dimension.</p>Results<p>This showed that 81.08% of participants displayed positive implicit perceived stigma (automatic group-negative associations), whereas only 25.68% displayed positive implicit internalized stigma (automatic negative self-linkages); he two implicit indices were uncorrelated. Explicit-implicit correlations were conditional: explicit internalized stigma was unrelated to both IRAP indices, explicit perceived stigma was only marginally associated with its implicit counterpart, and explicit perceived stigma showed a small positive correlation with implicit internalized stigma.</p>Discussion<p>These findings suggest that perceived and internalized stigma are functionally distinct at both reflective and spontaneous levels, and that robust implicit perceived stigma does not automatically translate into internalized self-stigma, consistent with a possible self-protective function.
