Emotion knowledge (EK) is a malleable set of skills that is central to social interactions and school success during early childhood. The current study describes an anti-racist approach to adapting an EK measure that assesses knowledge of facial expressions to be ecologically valid for young children of color attending pre-Kindergarten (pre-K) programs in a large urban school district. This approach involved (1) attending to race/ethnicity in selection of visual stimuli, (2) ensuring appropriate translation and language for administration, and (3) exploring the functioning of the measure within a racially, ethnically, and linguistically diverse group of children. A total of 235 children (67.4% Latinx, 14.1% non-Latinx Black, 7.1% non-Latinx White, 7.8% Asian, 3.6% another racial/ethnicity) were assessed in English (74%) or Spanish (26%) during the fall of pre-K (mean age = 4.4).
