Abstract Aims: Sleep disturbances and emotional dysregulation are critical concerns affecting the well-being and development of children and adolescents. This study investigated the bidirectional relationship between sleep and tonic irritability (i.e., angry mood), examining the moderating roles of self-control and anger rumination (i.e., non -adaptive emotion regulation strategies) in naturalistic settings.

Methods: A sample of 57 male adolescents, aged 12 to 18, engaged in a 9-day (4x a day) Ecological Momentary Assessment (EMA). Participants completed self-report questionnaires assessing levels of irritability, sleep quality, emotional regulation, and self-control. The hypotheses tested included (1) prior level of anger will predict subsequent night’s sleep quality, with prior self-control and anger rumination as moderators; and (2) sleep quality as a predictor of level of anger in the next assessment, with self-control and anger rumination playing the moderating role as well.

Results and Conclusions: Sleep quality predicted anger (β= -5.01; p=.001), moderated by both anger rumination (β_interaction = .05; p=.004) and self-control (β_interaction = .06; p=.003). Conversely, only self-control moderated relation between anger and the quality of the following night’s sleep quality (β_interaction = .01; p=.038). These findings highlight the intricate interplay between sleep and tonic irritability, emphasizing the important roles of anger rumination and self-control in these dynamics. This open new avenues in terms of prevention and early intervention that will be presented.
