        abstract = {Introduction
Dyspnea is a multidimensional symptom, but this multidimensionality is not considered in most dyspnea questionnaires. The Dyspnea-12 takes a multidimensional approach to the assessment of dyspnea, specifically the sensory and the affective response. The objective of this study was to translate into Spanish and validate the Dyspnea-12 questionnaire.

Methods
The original English version of the Dyspnea-12 questionnaire was translated into Spanish and backtranslated to analyze its equivalence. Comprehension of the text was verified by analyzing the responses of 10 patients. Reliability and validation of the questionnaire were studied in an independent group of COPD patients attending the pulmonology clinics of Hospital Universitario Marqu{\'e}s de Valdecilla, diagnosed and categorized according to GOLD guidelines.

Results
The mean age of the group (n=51) was 65 years and mean FEV1 was 50\%. All patients understood all questions of the translated version of Dyspnea-12. Internal consistency of the questionnaire was {\ensuremath{\alpha}}=0.937 and intraclass correlation coefficient was =0.969; P{\ensuremath{<}}.001. Statistically significant correlations were found with HADS (anxiety r=0.608 and depression r=0.615), mMRC dyspnea (r=0.592), 6MWT (r=?0.445), FEV1 (r=?0.312), all dimensions of CRQ-SAS (dyspnea r=?0.626; fatigue r=?0.718; emotional function r=?0.663; mastery r=?0.740), CAT (r=0.669), and baseline dyspnea index (r=?0.615). Dyspnea-12 scores were 10.32 points higher in symptomatic GOLD groups (B and D) (P{\ensuremath{<}}.001).

Conclusion
The Spanish version of Dyspnea-12 is a valid and reliable instrument to study the multidimensional nature of dyspnea.}
