The book will cover the ethics of a range of venues and situations where dual relationships are mandated, such as in the military, prisons/jails, and police departments, and settings where multiple relationships are unavoidable, such as rural communities; graduate schools and training institutions; faith, spiritual, recovery or 12-step, minority and disabled communities, total institutions, and sport psychology. The complexities of social network ethics and digital dual relationships, such as clients becoming "friends" or "fans" on their therapists’ social media pages are discussed. Finally, the book will discuss the complexities multiple roles that inevitably emerge in supervisory relationships.
