Further evidence of reliability and validity for the driving anger expression inventory.
This study provided evidence of reliability and validity for the four scales of the Driving Anger Expression Inventory. Alpha reliabilities for scales ranged from .84 to .89. Measures of aggressive anger expression while driving (Verbal Aggressive Expression, Personal Physical Aggressive Expression, and Use of the Vehicle to Express Anger scales) correlated positively with each other and negatively with the Adaptive/Constructive Expression scale. Scores on the three aggressive forms of anger expression correlated positively with trait anger and measures of driving-related anger, aggression, and risky behavior, whereas scores on the Adaptive/Constructive Expression scale correlated negatively with these variables. Reports of aggressive and risky behavior correlated most strongly with the Use of the Vehicle to Express Anger scale. Forms of anger expression were minimally or uncorrelated with rated trait anxiety and reports of moving violations, close calls, and accidents. Findings replicated earlier findings and provided further evidence for the reliability and validity of the Driving Anger Expression Inventory.
