8. Non-Reactive Methods
← 161 | 162 → CHAPTER EIGHT
Unobtrusive or non-reactive research refers to measures that are not obtrusive. In obtrusive research, participants modify their reactions or responses when they know that they are involved in a study. In unobtrusive research, people are not aware that they are being studied and so are not reactive to the research practice. An unobtrusive approach can make it easier to collect data. Analysis of physical evidence, secondary analysis, and content analysis will be addressed in this chapter.
