Mindfulness is a practice that has the potential to help counseling students build a variety of skills that are necessary for clinical efficacy, including therapeutic presence, attunement, empathy, cognitive flexibility, and non-reactivity. However, mindfulness is rarely taught to students in mental health training programs, which makes it an untapped possibility to improve counselor education. Additionally, rarely do researchers explore the role of counselor mindfulness and counselor trauma on clients' perceptions of therapeutic presence. Therefore, the purpose of this study is to explore the effects of a 15-week mindfulness training program for counseling students to understand its effect on client's perceptions of therapeutic presence, counselor state mindfulness development, and counselor trauma symptoms. Participants in this cluster-randomized controlled intervention were masters counseling students currently enrolled in clinical practicum accredited by the Counsel for the Accreditation of Counseling and Related Educational Programs (CACREP). Counselors provided data at three timepoints on their state mindfulness, trauma symptoms, and therapeutic presence. Clients provided data at three timepoints on their perceptions of their counselor's therapeutic presence. We analyzed data through repeated measures ANOVA and two-level longitudinal hierarchical linear models. Implications for counselor education, professional counselor development, and future research are offered and limitations are discussed.
