Cusp catastrophe model for binge drinking in a college population.

Area of Science:

• Psychology
• Behavioral Science
• Public Health

Background:

• Binge drinking is a significant public health concern among college students.
• Existing models, like the Theory of Planned Behavior, often use linear approaches to predict alcohol consumption.
• Catastrophe theory offers a non-linear framework to model complex behaviors.

Purpose of the Study:

• To develop and test a cusp catastrophe model for binge drinking behavior.
• To compare the predictive power of the catastrophe model against linear models.
• To explore the roles of attitude toward alcohol and peer influence in binge drinking.

Main Methods:

• A cusp catastrophe model was developed using attitude toward alcohol consumption and peer influence as control parameters.
• The model was applied to data from 1,247 students who completed the Core Alcohol and Drug Survey.
• Linear models, often associated with the Theory of Planned Behavior, were used for comparison.

Main Results:

• The cusp catastrophe model demonstrated a strong fit for binge drinking behavior (R² = .90).
• Linear models showed significantly lower predictive power for binge drinking (R² = .34).
• The model was also applied to frequency and quantity of alcohol use.

Conclusions:

• Catastrophe theory provides a superior framework for understanding and modeling binge drinking compared to linear approaches.
• The findings have significant implications for designing targeted interventions for alcohol misuse.
• Further research should explore the application of catastrophe theory to other behavioral phenomena.
