This is the data used in the article: "What happens when individual answer questionnaires in two different languages". The aim of the study was to compare scores from the English and the Spanish versions of two well-known measures of psychological distress using a within-subject approach. This method involved bilingual participants completing both measures in four conditions. For two groups of people, measures were offered in the same language both times and for the other two groups, each language version was offered, the order differing between the groups. The measures were the Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM; Evans et al., 2000, 2002)(CORE-OM; Evans et al., 2000, 2002)(CORE-OM; Evans et al., 2000, 2002)and the Schwartz Outcome Scale-10, both originally created in English and then translated to Spanish.

Participants are divided in four groups:) English on both occasions (EE), 2) English the first occasion and Spanish on the second occasion (ES), 3) Spanish the first occasion and English on the second occasion (SE), and 4) Spanish on both occasions (SS)
