Using vignettes to study nurse practitioners' performance in suspected domestic violence situations.

Vignettes have often been used to evaluate students or collect data in nursing research. The format is familiar to most nursing students as well as nurses and nurse researchers. This article presents the development and testing of the Nurse Practitioner Performance Tool (NPPT) which used vignettes as an approach to nurse practitioner performance evaluation. In this example, vignettes were used in a quasi-experimental design to collect data from Adult and Family Nurse Practitioners (A/FNP). The focus was on the diagnosis and intervention performance of the A/FNPs when addressing suspected cases of domestic violence.
