RESUMO
Social, behavioral, and health research among disenfranchised groups in inner cities poses problems in collecting data. It is a challenge to achieve data of sufficient quantity and quality necessary to be scientifically usable. This article describes the experiences of a research team during two phases of data collection in a mental health intervention study in New York's South Bronx. Challenges in addressing human subject concerns, the formation of a fieldwork team, enrollment and retention of respondents, and administration of instruments are described and solutions are discussed. Emphasis is placed on researchers' approaches to the selection, orientation, and safety of interviewers, interviewer-respondent race and ethnic matching, contacts and rapport with respondents, and the handling of such interpersonal issues as distrust, poor cooperation, and family dynamics. The procedures developed took into consideration the culture and life conditions of the population to ensure a satisfactory response rate and high-quality data.
