Modelling the relationship between poor sleep and problem anger in veterans: A dynamic structural equation modelling...

Area of Science:

• Psychology
• Sleep Science
• Military Health

Background:

• Problem anger and poor sleep are prevalent in military and veteran populations.
• The interplay between anger and sleep requires further investigation for effective treatment.

Purpose of the Study:

• To investigate daily fluctuations and dynamic relationships between sleep quality and anger experiences in veterans.
• To understand how sleep impacts anger frequency and vice versa.

Main Methods:

• Ecological Momentary Assessment (EMA) was used for daily monitoring.
• Sixty veterans with problem anger completed 10-day daily assessments of sleep and anger.
• A Dynamic Structural Equation Model (DESM) analyzed the data.

Main Results:

• A significant unidirectional relationship was found: poorer sleep quality predicted increased anger frequency the next day.
• No significant association was observed in the reverse direction (anger predicting sleep).

Conclusions:

• These longitudinal findings highlight a critical link between sleep quality and anger in veterans.
• Interventions for problem anger could benefit from incorporating sleep quality improvement strategies.
