Holistic methods have increased in popularity in the American culture. Interventions such as yoga, aromatherapy, mindfulness and walking therapy have been shown to be beneficial for the treatment of both physical and mental illnesses. However, little research exists regarding the use of holistic interventions in the field of counseling. This phenomenological study explores the experience of counselors who integrate holistic interventions into their practice and seeks to determine the essence of their development of self-efficacy. Co-researchers in this study included eight holistic counselors from rural, suburban and urban areas across the United States. Through semi-structured interviews, the co-researchers revealed the significance of personal experience with holistic methods, the influence of client feedback and the experience of formal and informal training on their development of self-efficacy. The findings of this study prompted recommendations for counselors who desire to integrate holistic methods and for the field of counselor education, including increased training and areas for future research.
