Affective polarization seems to have recently become one of the great topics in Political Science (Crespo et al., 2021). This issue has been deeply studied in the American context (Iyengar et al., 2019), although in recent years we can also find some research on affective polarization in European multiparty systems (see Wagner, 2021; Reiljan, 2020; Hernandez et al., 2020).

Until now, there is no academic consensus on how to measure affective polarization from survey results and academics are using different types of questions to construct similar indicators that, however, present comparability problems. Hence, the design of a survey questionnaire on a topic such as affective polarization, which should necessarily be multi-dimensional, is crucial if we want to correctly understand the phenomena we are studying. In this sense, this work aims to collect the main measuring instruments with which, until now, the study of affective polarization has been approached and to observe if these forms respond correctly to the theoretical formulation of the phenomenon.

To do this, we use our previous experience and the research carried out to design the First National Survey of Affective Polarization in Spain by the Murciano Center for Public Opinion last year -CEMOP- (2021) and the design process of the second for this year (2022). We propose a new measurement indicator that overcomes the difference between feelings towards parties and allows a more complex and holistic approach to the phenomenon.
