Literature on the mental health of Hispanics is reviewed in this book, which is organized according to a conceptual framework encompassing clinical service research. The book's division into five main sections reflects the five phases of the framework, which span the sequence beginning when a person experiences mental or emotional distress and ending after mental health providers have attempted to deal with the problem and the person attempts to resume his or her customary role. Phase 1, "Emergence of Mental Health Problems," documents the need for mental health services, and includes psychiatric epidemiologic studies of Hispanic populations. It serves as a foundation for the ensuing phases. The second phase, "Help-Seeking Behavior," includes studies of the factors influencing the utilization of mental health facilities. Research reviewed in Phase 3, "Evaluation of Mental Health," focuses on the cultural insensitivity of traditional assessment procedures for psychodiagnosis and evaluation, and on the effects of bilingualism, language of psychiatric interview, and the ethnicity of the examiner. In Phase 4, "Therapeutic Modalities," the focus is on the effectiveness of various forms of psychotherapy with Hispanics, and consequent adaptation of traditional treatment modalities tailored to Hispanic culture. The fifth phase, "Post-Treatment Rehabilitation," identifies the need for more knowledge about aftercare, rehabilitation, and recidivism in Hispanic patients. An appendix contains a discussion of Hispanic diversity in New York City. (KH)
