Individuals who are instrumentally aggressive have a unique perception and perspective of the world. They frequently engage in violent, threatening, and manipulative behaviors as a means of obtaining an ultimate goal, without consideration for the damage, injury, or harm that may occur. Similarly, adults with Antisocial Personality Disorder also tend to aggress without concern for injury toward others. This phenomenological qualitative study explored the possibility of a link between childhood instrumental aggression and the development of antisocial personality characteristics. This was done by assessing the phenomenological experience of those familiar with the cognitions, behaviors, and environments of instrumentally aggressive children. Specifically, qualitative interviews were conducted with 14 teachers and therapists who work with instrumentally aggressive children. This data was collected, coded, and analyzed to reveal major themes. Results of data analysis suggest that family relationships, setting, skill limitations, and social structure have significant influence on young children's developing personalities by shaping attitudes, thoughts, and interaction styles. Data analysis also revealed a high frequency of instrumental aggression and antisocial characteristics readily observable in several young children. When present, these traits appear to dominate social interaction, self-perception, and the behaviors of these children. Interviewees believe that this leads to personal isolation, social deficiency, and a tendency toward criminal action as the child matures.
