Insights from research on cross-cultural validation of health-related questionnaires - The role of bilingual project workers and lay participants

This article discusses the recruitment and training of bilingual project workers and their role in data gathering; the level of comprehension of the interviewees with regard to the nature of the task and its alien nature; the contribution of social customs and expectations; the vagaries of language; the researchers' level of comprehension of data collected across a range of languages; the feelings of loss of control by the researchers over the research process; and issues of communication with bilingual project workers. The authors draw on two studies designed to assess the adequacy of questionnaire translations from English into four ethnic minority languages: Cantonese, Punjabi, Urdu and Sylheti. Bilingual project workers were recruited to carry out interviews and focus groups with the lair communities and to feed back results in English to the researchers. The authors conclude that researchers should be aware of the influence of social and contextual factors when carrying out research with ethnic minority participants mediated by bilingual project workers.
