This timely text provides foundational knowledge and skills pertaining to ethical and evidence-based practice for mental health providers engaging in or considering using distance modalities to treat clients. Targeting day-to-day application, the book explains the core functions of telemental health counseling (TMH) and its use across a broad spectrum of mental health modalities and settings. Using the framework of the ACA divisions, ASCA, and CACREP core areas to examine TMH, the text provides instructions to develop skills that readers can apply directly to their own counseling interactions. Providing a wealth of information based on empirical and impartial views, the book helps readers examine the benefits and risks of distance counseling in various settings. It encompasses the history of TMH, ethical codes, legal guidelines, and recent research. Case studies and opportunities for self-reflection enable readers to envision distance counseling in real-world contexts, ask critical questions, and form conclusions about its utility in their practice. Of particular value is the "Voices from the Field" feature, where practitioners from different settings describe using distance counseling. The "Challenges and Opportunities" features discuss the pros and cons of telemental health practice. The book is written through the lens of professional counseling which makes it an ideal companion to counselor education program courses in counseling skills, pre-practicum, advanced theory, or elective coursework pertaining to distance counseling and telemental health.
