After they had learned exploration skills, 132 undergraduate helping skills students were taught to use the insight skill of immediacy. After training, students increased in self-efficacy for using immediacy, and catharsis and cohesion increased among lab group members. Students who completed training first (nondelay) had higher self-efficacy post-training than those in a delay condition before they had training. Self-efficacy for immediacy increased after lecture, modeling, and large-group discussion; decreased between lecture and lab; and increased after lab practice. Qualitative results indicated that practice was the most helpful component. Students with the highest initial self-efficacy and prior helping experience (PHE) had the highest post-training self-efficacy, whereas those with the lowest self-efficacy or the highest PHEs had the greatest self-efficacy increases. In addition, cultural background played a role in learning and using immediacy.
