Introduction: the beliefs, thoughts, feelings, behaviors and relationship with food, all together, constitute eating attitudes. Objective: to develop and perform the psychometric evaluation of the Spanish version of the Disordered Eating Attitude Scale (DEAS). Methods: the original scale was translated into Spanish, back translated and compared to the original version; discrepancies were not observed. The Spanish version was applied to Hispanic undergraduate female college students (n=218). Internal consistency was determined using Cronbach's Alpha; convergent validity was assessed by correlation (Spearman) between Spanish DEAS and the Eating Attitude Test -26 (EAT-26). Reliability was evaluated applying twice the scale to a sub-sample (n=26) within a 30 days interval. Spearman's correlation coefficient (r) was used to compare the test and retest scores. Results: internal consistency was 0,70. The DEAS total score was significantly associated with EAT-26 scores (r=0,54). The correlation between test-retest was r=0.81. Conclusion: the Spanish version of DEAS is reliable, valid and precise and will be useful to evaluate eating attitudes in different population groups and in eating disorder patients in Spanish spoken countries.
