In recent years there has been an increase in the use of cognitive pretesting methods for survey questions. This paper represents one such cognitive evaluation that was particularly interesting because the population of interest consisted of respondents who were difficult to recruit and for whom the topic of the questions was potentially sensitive. In addition, the interviewing situation was expected to be hampered by the respondents' language skills. This paper will focus on the method used to locate these respondents and the flexibility of the cognitive interviewing methodology employed in this evaluation.
