The document discusses the eclectic approach, which originated in the late 17th century. The eclectic approach refers to a problem-solving method that draws on multiple different principles and theories as needed rather than relying on a single method. An eclectic social work approach uses complementary, competing, or contradictory theories depending on the client's situation and needs. Advantages include addressing individual needs, combining strengths of methods, and treating disorders holistically, while disadvantages include difficulty identifying the contributions of each approach and managing complexity.
