Predicting heavy episodic drinking using an extended temporal self-regulation theory.

Area of Science:

• Psychology
• Behavioral Science
• Public Health

Background:

• Heavy episodic drinking poses significant global health risks.
• Temporal self-regulation theory and dual-process models offer frameworks for understanding this behavior.

Purpose of the Study:

• To evaluate temporal self-regulation theory's predictive power for heavy episodic drinking.
• To determine if dual-process model constructs enhance temporal self-regulation theory's predictions.

Main Methods:

• A predictive study involving 149 Australian adults.
• Utilized questionnaires and executive function tasks to measure theoretical constructs.
• Hierarchical multiple linear regression analyzed baseline measures against subsequent alcohol consumption.

Main Results:

• Temporal self-regulation theory significantly predicted heavy episodic drinking (R²=48.0-54.8%).
• The extended theory improved prediction of drinking frequency but not peak consumption.
• Intention and behavioral prepotency directly predicted heavy episodic drinking; planning and inhibitory control acted as moderators.

Conclusions:

• Temporal self-regulation theory, both standard and extended, effectively predicts heavy episodic drinking.
• Intention, behavioral prepotency, planning ability, and inhibitory control are potential intervention targets to reduce heavy episodic drinking.
