Much of the book's content is shaped by the editors' unique but complementary backgrounds that have led them down the path of preventive mental health. Dr. Jeste, a geriatric psychiatrist, has been interested in the prevention of cognitive impairment and the role of emotional aging. Dr. Bell has performed extensive research on violence and other social determinants of mental health. Traditional risk factors for mental illness are discussed throughout the book, but emerging research related to protective or resilience factors is also presented, bringing hope to many underserved communities that might be used to a more deterministic and reactive research model. As Dr. Bell states, “risk factors are not predictive factors because of protective factors” (p. 185). As each chapter presents the state of the science in identifying these resilience factors, one is struck by how findings from the Alameda County study (e.g., diet, physical activity, sleep) are echoed. Nonetheless, the psychological and emotional toll that persons with mental or behavioral disorders often experience can make adoption of these healthy behaviors especially challenging. Hence, what makes this book particularly important to the field of public health as well as to psychiatry is recognition that these prevention strategies must be accompanied by understanding of the underlying emotional, environmental, and psychological factors that can facilitate or impede health behavior change in vulnerable groups. Hence, from the complementary perspectives of Drs. Jeste and Bell, one can see how the broader field of health promotion/prevention research can in turn be shaped by this emerging psychiatric research.
