He expanded this into cognitive behavior therapy, and later into a multi-faceted psychotherapy known as multimodal therapy. In recent years, Lazarus has written popular psychology books. Lazarus has held numerous professional positions and won many honors. In 1996 he became the first recipient of the Psyche Award of the Nicholas and Dorothy Cummings Foundation.
