The aim of the present article is twofold First, it tests and demonstrates the supplementary use of focus groups to construct quantitatively oriented survey on anti-minority sentiment. Second, it clarifies two major theoretical concepts-prejudice versus perceived threat-in the research on discriminatory attitudes towards minority populations. More specifically, by using data from focus group discussions on foreign workers in Israel, the study examines the use of such groups for measurement of prejudice and perceived threat within the social and cultural context of Israeli society. The analysis of focus group discussions provides adapted questionnaire scales for measuring prejudice and perceived threat. The findings support the premise that prejudice and perceived threat are two distinct theoretical concepts. © 2010 Springer Science+Business Media B.V
