spheres characterize a person's personality. A prolonged imbalance or a crisis in any one of these three key interconnected spheres of mental health influences the others and can trigger defensive symptoms such as anxiety, anger, physical symptoms, depression or, in some cases, psychosis. Lifetrack Therapy: a personality model and therapy based on health To better understand and track psychological well-being, Ishizuka broke down the self, intimacy and achievement spheres into three dimensions with nine elements each. Using simple definitions and a subjective 10 point rating scale, he encouraged patients to take five to ten minutes daily to track the three spheres, as well as positive peaks of well-being (peace, friendliness, physical-health, happiness, mastery), negative peaks (anxiety, anger, physical symptoms, depression, psychosis), physical health, and proper use of food, beverage, or other substances. This tripod model of mental health is the basis for Lifetrack Therapy, a clinical approach drawing on the experience and insights accumulated by the daily self-rating data of more than 1,200 patients throughout their treatment on 41 parameters of mental health through periods of crisis to optimal health. The central goal for both the ‘distressed” and the “well” in Lifetrack Therapy is the same: health and well-being in the primary three spheres of life. Therapy sessions are focused on using crisis as an opportunity to transform the three spheres far beyond a previous best level of experience.
