Indicators of impulsive aggression: Present status of research on irritability and emotional susceptibility scales

Results of recent studies on Irritability and Emotional Susceptibility scales are presented. The developed scales have been proposed primarily for the research on individual differences concerning the manifestation of impulsive aggression. Principal-components analysis confirms the unifactorial structure of both scales and its stability with respect to groups of Ss of different language, nationality and cultural context. Content validity of both scales is clarified by their interrelationships with other measurements, and construct validity of both scales is clarified by a series of experimental studies.
