This casebook provides practical recommendations on a range of issues associated with electronic-based mental health care. From technologies as simple as the telephone to more advanced webcams and mobile device applications, psychologists are increasingly using technology in their work---a practice known as telepsychology. The book’s recommendations draw from the Guidelines for the Practice of Telepsychology, which were created jointly by the American Psychological Association, the Association of State and Provincial Psychology Boards, and the American Insurance Trust. Each chapter presents a guideline, explains how it relates to professional ethics and standards of care, and applies it to case examples.
