[Qualitative techniques for public health research and the development of health care services: more than just another technique].
Regarding the debate on the existence of two current focuses on health science research (qualitative and quantitative), the paper states the need for complementing the techniques which contribute to a better knowledge of populations and communities, and the need for offering effective solutions to different problems. The article analyses the usefulness of qualitative methods, describes the techniques and procedures more frequently used to guarantee the validity and reliability of research findings and ends bringing up the need for using qualitative and quantitative approaches. This way of working together or learning from each other will enrich research and interventions on public heath and health management fields. Qualitative methods are useful for sound understanding of a given issue that is being investigated or evaluated taking into account the point of view of the participants under research. Key techniques, listed from the most structured to the less structured are among others: structured interview, Delphi, nominal group, case study, semistructured interview, focal group, brainstorming, discussion group, in depth interview, life story and participant observation.
