“…Indeed, within an adolescent sample, youth with higher tonic irritability were observed to develop later depressive disorders and anxiety (Silver et al, 2021 ). However, some recent evidence has suggested greater impacts on functioning for youth with selective mutism who display phasic forms of irritability (Freitag et al, 2023 ), indicating the need for further studies parsing these constructs in the context of youth psychopathology. On the other hand, youth with ADHD demonstrate greater phasic irritability (i.e., increased outbursts and aggression) rather than persistently irritable mood (Cardinale et al, 2021 ; DeGroot et al, 2023 ).…”

Children prone to irritability experience significant functional impairments and internalising and externalising problems. Contemporary models have sought to elucidate the underlying mechanisms in irritability, such as aberrant threat and reward biases to improve interventions. However, the cognitive control processes that underlie threat (e.g., attention towards threats) and reward (e.g., attention towards reward-related cues) biases and the factors which influence the differential activation of positive and negative valence systems and thus leading to maladaptive activation of cognitive control processes (i.e., proactive and reactive control) are unclear. Thus, we aim to integrate extant theoretical and empirical research to elucidate the cognitive control processes underlying threat and reward processing that contribute to irritability in middle childhood and provide a guiding framework for future research and treatment. We propose an expanded conceptual framework of irritability that includes broad intraindividual and environmental vulnerability factors and propose proximal ‘setting’ factors that activate the negative valence and positive valence systems and proactive and reactive cognitive control processes which underpin the expression and progression of irritability. We consider the implications of this expanded conceptualisation of irritability and provide suggestions for future research.
