An introduction to key event mapping: A primer for nurse researchers.

To fully understand the events leading to a diagnosis, retrospective recall can help nurse researchers reconstruct important health behavior-related events. However, retrospective recall can be a challenge. Key event mapping offers nurse researchers a method beyond retrospective chart review to elicit date data to explore the pre-diagnosis time frame of an illness. The purpose of this paper is to introduce the key event mapping method to nurse researchers in search of a method of eliciting date data from participants when designing research studies that include a retrospective recall component.
