THE CORRELATION OF REPORTED VARIATIONS IN COUNSELOR PRACTICES WITH WELL-IDENTIFIED PERSONALITY TRAITS WAS STUDIED. THE SIXTEEN PERSONALITY FACTOR QUESTIONNAIRE (WHICH MEASURES 15 PERSONALITY TRAITS AND INTELLIGENCE) AND THE INVENTORY OF COUNSELING PRACTICES (WHICH EVALUATES 75 COUNSELING PRACTICES) WERE GIVEN TO 120 GRADUATE GUIDANCE STUDENTS AT ARIZONA STATE UNIVERSITY. A CRITERION FACTOR ANALYSIS YIELDED FOUR FACTORS COMMON TO BOTH INSTRUMENTS. THESE FACTORS DEPICT FOUR PROTOTYPE COUNSELORS. THE SELF-SUFFICIENT COUNSELOR, WHO ACTIVELY STRUCTURES INTERVIEWS, IS RESOLUTE AND HAS A RATIONAL, DIRECT APPROACH. THE PROBING COUNSELOR, ANALYTICALLY SEEKING THE MOTIVES OF HIS CLIENTS, IS HIGHLY MORAL, CONSCIENTIOUS, AND PERSISTENT. SUCH A COUNSELOR SEES HIMSELF AS A GUARDIAN OF SOCIAL MORAL VALUES. THE RIGID, TASK-ORIENTED COUNSELOR IS MOTIVATED BY A NEED FOR ACHIEVEMENT. HE IS AMBITIOUS, IMPATIENT, TENSE, AND CONTEMPTUOUS OF THE AVERAGE. HE HAS LITTLE PATIENCE WITH THE CLIENT-CENTERED APPROACH. THE DEPENDENT, IMAGINATIVE, UNCONVENTIONAL COUNSELOR IS IMMATURE IN PRACTICAL MATTERS. HE AVOIDS RESPONSIBILITY AND FORCES IT ONTO HIS CLIENT. INTELLIGENCE APPEARS TO BE INDEPENDENT OF ATTITUDES TOWARD VARIOUS COUNSELING TECHNIQUES. WITH THE LARGER SAMPLE, ADDITIONAL RELATIONSHIPS MAY BE DISCOVERED. (PR)
