Methodological aspects of rigor in qualitative nursing research on families involved in intensive care units: a literature review.

摘要

Rigor has important ramifications for the entire qualitative research process. The aim of this study was to evaluate aspects of methodological congruence by focusing on four dimensions of rigor in qualitative nursing research related to the presence of patients' family members in the intensive care unit. Eight research papers covering the years 1990-2004 were analyzed by means of one of Burns and Grove's standards, methodological congruence, for critique and consistency. The results show that there are varying degrees of focus on procedural rigor, such as limitations and bias. Ethical rigor is described clearly in some papers, while others lack descriptions of confidentiality and the voluntary nature of participation. However, all papers contain descriptions of qualitative data analysis. In conclusion, there were strengths in procedural rigor and auditability, but also some limitations in the identification of theoretical development and the scientific tradition on which the article is based.
