AbstractThis study compared focus groups and in-depth interviews in terms of number of factors generated, time and cost requirements, and ease of data collection. Participants were 18 to 24 year old Hispanic and Anglo college women. The discussion topic was factors influencing food choices. Eight focus groups were conducted, four Anglo (n = 13) and four Hispanic (n = 12). Thirty-eight Anglo (n = 16) and Hispanic (n = 12) in-depth interviews were completed. A total of 83 unique factors were identified. Focus groups and in-depth interviews yielded 79 and 73 factors, respectively. The mean number of factors for focus groups was 33.8 compared to 37.0 for randomly selected in-depth interviews grouped to form "nominal groups". However, this was not a significant difference. Focus groups required 66.8 hours and cost $292.40 to yield 79 factors while in-depth interviews required 147.0 hours and cost $624.75 for 73. Focus groups were more difficult to arrange but easier to conduct.
