The Association Between Family Conflict and Child Impulsivity: Child Sleep Problems as a Mechanism

Area of Science:

• Child Psychology
• Developmental Neuroscience
• Behavioral Science

Background:

• Family conflict is a known risk factor for adverse child outcomes.
• Childhood impulsivity and sleep disturbances are significant public health concerns.

Purpose of the Study:

• To investigate the longitudinal relationships between family conflict, sleep problems, and multidimensional impulsivity in children.
• To examine the mediating role of sleep problems in the association between family conflict and impulsivity.

Main Methods:

• Analysis of data from 11,878 children and their parents in a large, multi-site U.S. national sample (Adolescent Brain and Cognitive Development Study).
• Longitudinal assessment of family conflict, sleep problems, and impulsivity facets (lack of perseverance, lack of planning, negative urgency, positive urgency, sensation seeking) over three years.

Main Results:

• Higher family conflict at Year 1 predicted increased sleep problems at Year 2.
• Sleep problems at Year 2 predicted higher levels of lack of perseverance, lack of planning, negative urgency, and positive urgency at Year 3.
• Sleep problems mediated the relationship between family conflict and these dimensions of impulsivity.

Conclusions:

• Family conflict negatively impacts children's sleep, which in turn promotes the development of specific facets of impulsivity.
• Ensuring good quality sleep is vital for children exposed to family conflict, potentially buffering against developmental disruptions in self-control.
