Adaptation and cross-cultural validation of the Decisional Conflict Scale for use in Brazil

Abstract

Objective: To realize the cross-cultural adaptation and evaluation of the psychometric properties of the Decisional Conflict Scale for Brazilian Portuguese. Methods: Methodological study of cross-cultural adaptation. It followed five steps: translation, synthesis, reverse translation, evaluation by an expert committee and validation with 190 nursing students. The construct validity was verified through exploratory factor analysis, adopting the Kaiser-Meyer-Olkin statistic, and the Screeplot and Engevalues analyses. Cronbach's Alpha was used to assess the internal reliability of the subscales. Results: The Content Validity Coefficient of the items reached an agreement of 0.79. Kaiser-Meyer-Olkin stat with a score of 0.91, suitable for the next step. The Screeplot analysis showed a two-factor distribution, confirmed by the Engevalues analysis. The Exploratory Factor Analysis revealed two subscales: the first Decision, Uncertainty and Support and the second Information and Clarity of Values, with Cronbach's alpha coefficients of 0.88 and 0.89. Conclusion: The Brazilian Portuguese version of the Decision Conflict Scale, Conflict in Decision Making Scale, presented two subscales with adequate evidence of validity and reliability, enabling the identification of factors that influence decision conflict in the health-disease process.
