Adventure therapists work with a wide range of clients with differing behaviors. Some of the clients’ belief systems, preferred behaviors, and value systems are not only different than those of the therapists who work with them, but may involve situations where the differences cause some sort of conflict between client and therapist. One way adventure therapists can address nonnegotiable values is to proactively identify those beliefs, behaviors, and values that they are unwilling to negotiate to be able to work with a client. Along with determining appropriate clients to work with in adventure therapy, it is important to be fully cognizant of what are considered ethical behaviors in the field. The chapter highlights one ethical decision-making model that uses the intersecting perspectives of three sources of ethical decision-making relevant to the adventure therapy field: principle ethics, virtue ethics, and feminist ethics. One ethical debate in the adventure therapy field is the involuntary transport of adolescents to adventure therapy treatment settings.
