The problem of this study was the determination of the relationship between Myers-Briggs personality temperament and extraversion-introversion, and group counseling norms, as reflected by the group counseling outcome measures: Survey of Attraction to Group, self and leader-report Interpersonal Relationship Rating Scale (IRRS), and Sociometric Choice Status Survey. The Mvers-Briggs Temperament Indicator (MBTI) and the four outcome measures were administered to a sample population of 103 graduate and undergraduate counselor education students after completion of a semester-long group counseling experience. Fifteen groups of five to nine members were surveyed. It was expected that group members whose temperaments were compatible with group counseling norms would be more likely to receive confirmation, support, and acceptance in the group, be attracted to the group, receive higher leader and self-report ratings of interpersonal skills, and be more highly valued by other members than would members whose temperaments were incompatible with group norms. It was also thought that extraverts were more likely to be attracted to the group, receive higher self and leader ratings of interpersonal skills, and to be more highly valued by other members than were introverts. No significant relationship was found between temperament and the four outcome measures. Possible explanations for this finding were discussed. However, mean scores for extraverts were significantly higher than mean scores for introverts on the Survey of Attraction to Group and leader-report interpersonal Relationship Rating Scale instruments. A related finding was that the NF temperament was overrepresented in the sample population of counselor education students by a factor of four. The INFP type was overrepresented by a factor of 16.5, and the ENFP type had the highest frequency of occurrence. Together, INFPs and ENFPs constituted 34 percent of the sample. In the general population, INFPs and ENFPs would be expected to account for only six percent of the total.
