Emotion regulation is crucial for psychological well-being, particularly in children and adolescents. The use of ineffective regulation strategies has been identified as an early indicator of mental health problems, including depression and anxiety (e.g., Joormann & D'Avanzato, 2010). Cognitive processes such as intelligence and executive functions have also been linked to effective emotion regulation (e.g., Bridgett et al., 2013). This study examines the effects of intelligence and executive functions on both cognitive and behavioral emotion regulation strategies using path analysis. Data will be drawn from a subset of the U.S. standardization sample (N = 166) who completed both the Intelligence and Developmental Scales -2 (IDS-2; Grob & Hagmann-von Arx, 2028; U.S. adaptation in preparation) and the new Emotion Regulation Strategies Questionnaire (FEEL-KJ-2; Grob et al., 2025), which assesses both cognitive and behavioral strategies. Based on previous findings (Te Brinke et al., 2021), we hypothesize positive effects of intelligence and executive functions on cognitive strategies, and negative effects on behavioral strategies. These results will highlight the value of multidimensional, evidence-based assessments of cognitive factors for understanding the origins of emotional regulation difficulties in children and adolescents and for informing targeted interventions to improve mental health.
