To work as a clinical psychologist is to experience the immense satisfaction of helping people overcome emotional and psychological difficulties. Unlike psychiatrists, clinical psychologists do not prescribe medications and instead address psychological issues with a variety of techniques that depend in part upon their area of specialty. Specialization in the field of clinical psychology may come by the choice of theoretical framework, such as cognitive-behavioral, psychodynamic, humanistic, family systems, positive psychology, transpersonal or existential. Specialization may also be achieved by focusing upon a specific disorder or condition such as depression, schizophrenia, addiction or learning disabilities (to name a few) or upon a particular demographic such as children, families, adults or the elderly.
