Relationship between age and emotion reactivity (ERS total score), emotion regulation (DERS total score), cognitive reappraisal (ERQ cognitive reappraisal), and expressive suppression (ERQ expressive suppression) in clinical high-risk for developing psychosis (CHR, purple), adolescent-onset psychosis (AOP, blue), and typically developing (TD, orange) across development. Over time, levels of (a) global emotion reactivity, (b) overall impairment in emotion regulation via the DERS, and (c) engagement in cognitive reappraisal and (d) expressive suppression remain stable across development in CHR, AOP, and TD.
