The purpose of this study was to investigate the role of personality traits of counselors-in-training with regard to counseling performance. There were no differences in pretest or posttest scores on the Skilled Counseling Scale (SCS) of high and low self-monitoring counselors-in-training. Skill attainment may have more effect on personality traits than traits have on skill attainment. Both Interpersonal Process Recall (IPR) and Skilled Counselor Training Model (SCTM) groups improved their scores on the SCS, but the SCTM group improved significantly more than the IPR group.
