Title: The Driving Appraisal Inventory: Psychometric characteristics and construct validity.

Four studies examined the dimensionality, reliability, and construct validity of the Driving Appraisal Inventory (DAI), a self-report measure of driving habits and skills. In Study 1, analysis of 127 items led to the formation of four unidimensional, internally reliable scales: Carelessness, Drunken Driving, Vehicle Safety, and Self-Evaluation. In Study 2, all were found to have acceptable test-retest reliability. In Study 3, convergent validity support was obtained for the Carelessness and Vehicle Safety scales. In Study 4, concurrent criterion-related validity support was obtained for the Carelessness and Drunken Driving scales. Scores on the Self-Eevaluation scale appear to be more a function of self-confidence and/or ego-involvement in driving skills and less a function of actual driving skills. Men score higher than women do on the Carelessness, Drunken Driving, and Self-Evaluation scales, and in Study 4, criterion-related validity of the Self-Evaluation scale was stronger among women than among men.
