Anger expression among Danish cyclists and drivers: A comparison based on mode specific anger expression inventories

Area of Science:

• Psychology
• Transportation Research

Background:

• Anger expression in drivers is well-researched using the Driving Anger Expression Inventory (DAX).
• Cyclists' unique traffic interactions necessitate a tailored anger expression assessment.

Purpose of the Study:

• To adapt the DAX for cyclists, creating a reliable Cyclist Anger Expression Inventory (CAX).
• To compare anger expression patterns between drivers and cyclists.
• To investigate demographic and attitudinal factors influencing anger expression in both groups.

Main Methods:

• An online survey of 2000 Danish inhabitants (drivers and cyclists).
• Principle component analysis of the adapted DAX-short (14-item CAX).
• Statistical analyses including linear regression to examine demographic and attitudinal influences.

Main Results:

• The CAX confirmed a 4-factor structure, excluding 'use of a vehicle to express anger' for cyclists.
• Drivers exhibited higher verbal aggressive expression than cyclists; no difference in constructive expression.
• Age and gender significantly predicted anger expression, with women showing less physical expression and older individuals more constructive expression.
• Positive driving attitude correlated with anger expression in drivers, but not cyclists.

Conclusions:

• The CAX is a reliable tool for assessing cyclist anger expression.
• Significant differences exist in anger expression between drivers and cyclists.
• Demographic factors and attitudes play a crucial role in anger expression across different road users.
