Introduction
The introduction sets the stage for the book to follow: it describes the 2020 Covid-19 pandemic; the losses, risks, and life changes it is entailing; and their psychological consequences. A crisis evokes strong, distressing feelings and symptoms. The introduction presents interpersonal psychotherapy (IPT), a proven, time-limited treatment for mood, anxiety, and posttraumatic disorders, as likely to be a helpful response to this crisis. IPT is a life event–based therapy for symptoms due to an overwhelming global series of life events. The brief introduction alerts the reader to the main psychiatric consequences of major life disruption and trauma: anxiety, depression, and posttraumatic stress, which succeeding chapters will cover. It describes the forced switch to tele-psychotherapy and provides a rationale for why interpersonal therapy is likely to benefit many people sustaining these losses.
