DrSligh Is a Practicing Therapist in a Rural Area, Who

Dr.Sligh is a practicing therapist in a rural area, who was trained as a couples therapist.His caseload is shrinking because Dr.Phil seems to have helped a lot of the troubled couples in this area.In order to increase his practice, Dr.Sligh completed extensive additional training in child therapy and family therapy (including both formal course work and supervised clinical training) .He now seeks to market himself as a child therapist and as a family therapist, in addition to being a couples therapist.This situation is:

A) Unethical, because no one has the capacity to have expertise in child therapy, family therapy, and couples therapy
B) Unethical, because Dr. Sligh's graduate training was only in couples therapy
C) Unethical, because the people in this rural area are isolated and are at risk for abuse from a slick psychotherapist
D) Ethical, because Dr. Sligh gained competence in the new areas of training through formal course work and supervised clinical training
