摘要：The purpose of this article is to examine some obstacles and dilemmas related to methodological strategies and ethical considerations that arose during the fieldwork of research focused on family violence during the stages of pregnancy and childbirth in adolescent females in Buenos Aires during 2007. From this study, we are able to contribute some reflections in the arena of qualitative and mixed methods inquiries. Some of the problematic topics encountered were: institutional constraints, questionnaires with categories too abstract for the target population, lack of interest in participating, orthodox methods that did not work in the field and ethical protocols that only focused on informed consent. We conclude that optimizing a research endeavor is affected by the emergent components of fieldwork, and the reformulation and incorporation of new techniques of data collection should be suitable to the specific requirements of the population under study.
