Professional issues: psychologists examine elements of their own profession through empirical research. Research is conducted to learn about the best ways of teaching and training new psychologists. Efficacy: refers to success of a particular therapy in a controlled study conducted with clients who were chosen according to particular study criteria. Effectiveness: refers to the success of a therapy in actual clinical settings in which client problems spans a wider range, and clients are not chosen as a result of meeting certain diagnostic criteria.
