The Internalized Shame Scale (ISS) is a self-report measure which assesses trait shame, composed by an Internal Shame subscale, measuring internalized shame, and a Self-Esteem subscale. The Internal Shame and Self-Esteem subscales present a one-dimensional structure. The subscales present high internal consistency, and an excellent temporal stability. Convergent and discriminant validity of the subscales was corroborated through the moderate correlations with a measure of shame and of social comparison, and through the low and moderate correlations with the subscales Depression, Anxiety, and Stress. The Portuguese version of the ISS is a valid and reliable instrument to measure internalized shame.
