The Appearance-Related Social Media Consciousness Scale: Development and validation with adolescents

= 16.25). ASMC scores demonstrated strong internal consistency, convergent and incremental validity, and test-retest reliability (measure re-administered for n = 207). Higher ASMC was associated with higher depressive and disordered eating symptoms, controlling for time on social media, gender, race/ethnicity, and body surveillance. Girls reported higher mean scores than boys. Findings support the use of this 13-item scale in reliably assessing adolescents' ASMC, which may have important implications for mental health in the age of social media.
