The nurse researcher who is new to qualitative research believes that saturation of data has occurred after interviewing seven study subjects. What question would help determine if this is true?
1. Are any new themes or information emerging from the interviews?
2. Has the researcher reached the number of study subjects chosen for the study?
3. Do any of the study subjects know one another?
4. Is the researcher ready to analyze the data?
1
Rationale 1: This is the appropriate consideration for whether saturation has been achieved. If no new themes or information are emerging, saturation has been reached.
Rationale 2: Qualitative studies do not have a set number of subjects. The researcher continues interviewing until saturation is reached.
Rationale 3: If the researcher is concerned that data are inaccurate because study subjects know one another or are "comparing notes" regarding the interviews, the issue at hand is the quality of all of the data, not if the data have achieved saturation.
Rationale 4: Data in a qualitative study are analyzed as they are collected. The researcher would not suspect that saturation has occurred unless the data had already been analyzed.
