Current psychoanalytic theory (based mostly on case studies) has documented a negative relationship between psychosomatic illness and mentalization: as the level of mentalization decreases the level of psychosomatic illness increases because the mind must develop sufficiently for it to identify and processes signals from the body. Psychoanalytic theory states that in the absence of mentalization, psychosomatic symptoms may develop. Yet, well-developed mentalization may also produce strong and persistent negative thoughts and feelings resulting in psychosomatic illness. In addition, health science literature reports that this relationship is in a positive direction. This book examines the relationship between psychosomatic illness and the ability to image using quantitative data obtained through reliable and valid instruments and a case study. This book helps readers of all interests reach a deeper understanding of the powerful relationship between one’s psychological processes and one’s body and will increase understanding of health, which may inform practice.
