We aimed to validate the Spanish version of Decisional Conflict Scale (DCS) and analyze its psychometric properties in people with migraine.The DCS validation comprised two phases. First, a translation cross-cultural adaptation following International Society for Pharmacoeconomics Outcomes Research (ISPOR) Good Practices: 1-preparation, 2-independent forward translation, 3-reconciliation, 4-back-translation, 5-harmonization, 6-clinical review, 7-content group migraine patients. Second, analysis properties. The reliability or internal consistency scale subscales was assessed using Cronbach's α value. item-subscale correlation also evaluated. A floor ceiling effects score considered when at least 15% respondents obtained >90 (ceiling) <10 (floor). construct validity studied through between by other questionnaires (Decision Self-Efficacy [DSES] 9-item Shared Decision-Making [SDM-Q-9]). Spearman's coefficients were estimated correlations.The conducted on 17 patients who completed questionnaire mean 2.4 ±1.1 minutes. Generally, more than 75% them that items adequate, easy understand, relevant. evaluated sample n=128 Accordingly, high, 0.97 0.87 0.96 subscales. Also, slight effect observed, 24.2% having scores <10. exceeded coefficient 0.7. Whereas generally moderate (Spearman's >0.4).The (Spain) has very acceptable (reliability validity) good potential assessing decisional conflicts among
