In 1952 Redlich co-edited with
Eugene Brody the widely read book, "Psychotherapy With Schizophrenics." Redlich is best known within the field of Community Mental Health for his groundbreaking study done in the late 1950s with sociologist August Hollingshead. In the study, "Social Class and Mental Illness" the two researched the mentally ill population of New Haven, Connecticut and the treatment they received within a calendar year. Two aspects of the study have contributed to its historical significance. First, was the large, almost complete sample of all people from New Haven who sought psychiatric treatment in that year. This was achieved by identifying and communicating with psychiatric practitioners throughout the eastern United States as well as within New Haven. The second aspect of the study was its definition of social class by income level with the designation of five social classes using the Roman numerals I though V (V being the poorest). This system of class designation is still utilized in current social science research. The outcome of the study demonstrated that the majority of people in the upper two social classes received insight or talking therapy which was non-bodily intrusive and took place in private settings. The majority of the lowest social class received their treatment in public institutions. Their treatment consisted primarily of constraint and intrusive methods ( such as cold packs, electroshock, and lobotomies). The conclusions of their study were that social class plays a significant role in psychiatric diagnosis and treatment, with the upper social classes receiving less intrusive therapy. ==Bibliography==
