Predicting driving anger from trait aggression and self-control.

Undergraduates (N=115) completed the Propensity for Angry Driving Scale, Driving Anger Scale, and measures of trait aggression and self-control. Aggression and self-control correlated significantly with scores on the two scales, and Aggression subscale scores explained significant unique variance in both, but the predicated interaction of aggression and self-control was not significant. The Propensity for Angry Driving Scale is recommended to measure self-reported aggressive driving, and the Driving Anger Scale for assessment of driving-related anger.

Positive illusions: positively correlated with subjective well-being, negatively correlated with a measure of personal growth.

Psychologists have long debated the benefits and costs of self-deceptive enhancement or positive illusions. Accurate perception of reality is central to the definitions of mental health proposed by many personality and clinical psychologists, but Taylor and Brown have suggested that having positive illusions is associated with increased happiness and satisfaction with life. One explanation for the conflicting assertions is that mental health, broadly defined, includes both subjective well-being and personal growth, distinguishable factors which are differentially related to positive illusions.
