Introduction: Allophilia may be defined as the positive attitudes toward different out-groups. The aim of this study is to translate and validate the Allophilia Scale to Spanish population. Method: Participants were 960 individuals from all over Spain. Questionnaires to measure prejudice toward North African people, stress and empathy were used to analyze the convergent and divergent validity of the Allophilia scale. Results: Confirmatory factor analysis showed that the items of the questionnaire fit a model with five factors, corresponding to the dimensions proposed by the original authors (Affection, Comfort, Kinship, Engagement, Enthusiasm), and that they were inter-related. Cronbach's alpha of the Allophilia scale and the five factors were high. In addition, it has been found that the different sub scales of the Allophilia scale were related with other variables such as prejudice toward North African people (cognitive, emotions and behaviours), stress (interaction, resources, identity) and empathy. Discussion: In light of these results, we conclude that the questionnaire is methodologically valid and can be used by the scientific community to measure cooperative and participatory intergroup behaviour as a complement to traditional measures of prejudice and negative intergroup behaviours.
