This is another article examining the effects of participants' cultural backgrounds on methods of usability studies. The authors reports a controlled study comparing the results of interviews with two groups of participants, one Indian and the other Anglo-American conducted by two groups of interviewers from the corresponding cultural groups of the participants. The results led the authors to conclude that culture (both on the participants' side and the interviewers' side) is a significant variable in international user testing and usability studies.

This article echoes the work of Hall et al. (2004). These are useful finding for researchers and practitioners to design their research and minimize bias that results from the lack of consideration of the participants' and the researchers' cultural background or identification, as well as the nature of the research questions.
