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.

Scores on the Beck Depression Inventory were compared for 25 women who had silver dental fillings (amalgams) and for 23 women without amalgams. Women with amalgams had significantly higher scores and reported more symptoms of fatigue and insomnia. Anger scores from the State-Trait Anger Expression Inventory showed that the women with amalgams had statistically significantly higher mean scores on expressing anger without provocation and experiencing more intense angry feelings. The women without amalgams scored significantly higher on controlling anger, which suggested they invested more energy in monitoring and preventing the experience and expression of anger. Anxiety scores from the State-Trait Anxiety Inventory showed the women with amalgams scored significantly less pleasant, satisfied, happy, secure, and steady, and had a more difficult time making decisions. They had significantly higher Trait Anxiety scores. The women with amalgams also had significantly higher levels of mercury in the oral cavity before and after chewing gum. The study suggests that amalgam mercury may be an etiological factor in depression, excessive anger, and anxiety because mercury can produce such symptoms perhaps by affecting the neurotransmitters in the brain.

This study was conducted to provide further evidence of reliability and validity for the Driving Anger Scale, French version. A sample of 202 drivers, ages 18–25 years, completed the scale and the general Trait Anger scale from NEO Personality Inventory-Revised. Factor analysis indicated five factors similar to those found in the original U.S. version. The ‘Traffic Obstructions’ and ‘Slow Driving' factors have been slightly modified, and ‘Discourtesy’ was abandoned. Positive correlations were observed between scores on the Trait-Anger scale from the NEO Personality Inventory-Revised and the Driving Anger Scale ( r = .41) and with its factors (from .24 to .38), except for ‘Illegal Driving’. The internal consistency of the Driving Anger Scale was acceptable for the total score (α = .82) and for factors ranged from .74 to .80. This French version can be preliminarily recommended for the assessment of driving anger in France among young drivers.
