Negative attitudes towards out-groups have been of academic interest for many years — and even more so with the increased levels of migration to European countries in recent years. Building on insights from intergroup contact theory, this paper seeks to extend our knowledge of the association between contact and negative attitudes toward immigrants among youth in Sweden. Multiple regression analysis and fixed effects models are used to analyze a large, high-quality dataset on Swedish adolescents based on representative survey information, complemented with extensive registry data and official statistics. Our objective is to measure contact on different levels in order to better understand the importance of these different contact variables’ associations with negative attitudes. The results of the analysis indicate that high-quality contact in the form of friendship is associated with a reduction in negative attitudes among Swedish adolescents, even after controlling for background variables. Superficial forms of contact — measured on the school level — are, on the other hand, associated with an increase in negative attitudes.
