In an increasingly diverse society, psychotherapists must be able to work effectively with a wide variety of clients.

Her ADDRESSING framework encompasses Age and generational influences, Developmental or other Disabilities, Religion and spirituality, Ethnic and racial identity, Socioeconomic status, Sexual orientation, Indigenous heritage, National origin, and Gender. This third edition is richly illustrated with case material and includes up-to-date information on the DSM-5, ICD-10, and upcoming ICD-11, plus new sections on working with people in poverty, children, and transgender people; and trauma-informed care. Each chapter includes a Key Ideas summary and practice exercises, making it ideal for personal education or group use.
