Many studies on language attitudes have been based on an approach in which languages are examined as an isolated unit; in other words, in these studies the participants are asked about their attitudes towards each of the languages in contact independently, by using what we will label in this chapter as monolingual biased questionnaires. The objective of this paper revolves around the analysis of language attitudes towards trilingualism by means of a holistic questionnaire in two multilingual contexts (the Basque Country and Malta). Our results reveal that the holistic questionnaire can be a useful tool to complement traditional questionnaires and it could lead to further knowledge on languages as a whole, rather than treating them separately. Furthermore, in can be a useful tool in order to enhance language awareness and enable language teachers to reflect both on their own language skills and competence as well as those of their students.peer-reviewe
