A Clinical Nurse at a Large Urban Hospital Decides to Conduct

A clinical nurse at a large urban hospital decides to conduct a descriptive qualitative study related to staff nurses' perceptions of the causes of various types of violence against nurses in that facility. As part of the research design, the nurse hosts a series of focus groups with staff nurses during each of three shifts. What is considered the main advantage of using a focus group strategy as opposed to one-on-one interviews for data collection?

A) People from differing social and cultural backgrounds tend not to share information as well as those who have common experiences.
B) Focus groups allow full expression of individual voices and contrasting viewpoints, controlling bias.
C) Focus groups can be spontaneous, and they require little advance planning or forethought.
D) A focus group makes it possible to obtain the prevailing opinion of a small cluster of people in a fairly short period of time, as opposed to the strategy of one-to-one interviewing.
