Externalizing Behaviors and Callous-Unemotional Traits: Different Associations With Sleep Quality

Area of Science:

• Psychology
• Sleep Science
• Clinical Psychiatry

Background:

• Sleep quality is linked to various psychopathology aspects.
• Research on sleep quality's connection to externalizing behaviors and callous-unemotional traits is limited.

Purpose of the Study:

• To investigate the association between sleep quality and externalizing behaviors.
• To determine if anxiety mediates the sleep quality-externalizing behavior link.
• To examine the relationship between sleep quality and callous-unemotional traits.

Main Methods:

• Two studies utilized questionnaire data from 1556 (Study 1) and 338 (Study 2) participants.
• Measures included sleep quality, anxiety, externalizing behaviors, and callous-unemotional traits.
• Objective sleep quality was assessed using actigraphy in a subsample of Study 2.

Main Results:

• Poorer self-reported sleep quality correlated with increased externalizing behaviors in both studies, partially mediated by anxiety.
• Callous-unemotional traits showed no significant relationship with poor sleep in Study 1.
• Better sleep quality (objective and self-reported) was associated with higher callous-unemotional traits in Study 2.

Conclusions:

• Self-reported poor sleep quality is associated with externalizing behaviors, with anxiety as a partial mediator.
• Callous-unemotional traits are not linked to poor sleep and may be associated with better sleep quality.
• This finding contrasts with the typical association between poor sleep and psychopathology.
