Amostragem e saturação em pesquisa qualitativa: consensos e controvérsias

TLDR: Palavras-chave as discussed by the authors discusses sampling and saturation in qualitative research and discusses the following questions: To what extent individual interlocutions obtained in the field can be understood as revelations of the group and allow inferences about it? What would be the preconditions for a sufficient and reliable sample? In a project, should the number of people to be interviewed and the time for field observation be established previously? How many interviews and how much observation time are needed for a good fieldwork? When should the search for more data be discontinued?

Abstract: Resumo: Este ensaio sobre amostragem em pesquisa qualitativa e sobre o conceito de saturacao discute as seguintes questoes: em que medida as interlocucoes individuais que se obtem no campo podem ser entendidas como revelacoes do grupo e permitir inferencias sobre ele? Quais seriam as precondicoes para uma amostra suficiente e fidedigna? Num projeto, deve-se colocar previamente o numero de pessoas a serem entrevistadas e um tempo determinado para a observacao de campo? Quantas entrevistas e quanto tempo de observacao sao necessarios para um bom trabalho de campo? Quando se deve parar de buscar mais dados? As respostas sao balizadas na literatura e na experiencia pessoal da autora, mostrando que a quantificacao a priori foge a logica que preside os estudos qualitativos.

Sampling and saturation in qualitative research: consensuses and controversies Abstract: This essay on sampling in qualitative research and on the concept of saturation discusses the following questions: To what extent individual interlocutions obtained in the field can be understood as revelations of the group and allow inferences about it? What would be the preconditions for a sufficient and reliable sample? In a project, should the number of people to be interviewed and the time for field observation be established previously? How many interviews and how much observation time are needed for a good fieldwork? When should the search for more data be discontinued? The responses are based on the specific literature and on the personal experience of the author, showing that, in principle, quantification escapes the logic of qualitative studies.
