Some therapies presuppose that a person seeks professional help because they do not know what to do to solve and/or resolve their problems. Other therapies postulate that clients do know - they are the experts. Evaluate the strengths and limitations of these perspectives. Explain the clinical circumstances in which either might be indicated and effectively applied, and, the clinical circumstances in either model might be contraindicated and inapplicable. Provide an example of each to illustrate.
