The major purpose of this study was to determine the relationship between selected personality characteristics and attitudes of male extension agents in Wisconsin, and their level of job performance. The relationships between selected background factors and the level of agent's job performance were also studied. Subjects were 79 male county agents working in 30 randomly selected counties. A significant relationship between total job performance and the personality characteristics of sense of well-being and communality revealed that the agents with low scores on these two personality characteristics (and thereby expressing themselves as being conventional, cautious and stereotyped) were rated better than average in total job performance. Significant relationships existed between performance in evaluation and the personality characteristics of sense of well-being and responsibility. Favorable attitudes toward the Extension professional improvement as rated by district supervisors were significantly related to better than average total job performance and performance in each of the five areas. The position of agents in the Extension Service had a significant relationship to performance in evaluation, office management, and working relationships. Educational background influenced job performance. (Author/NL)
