Method: A total of 204 participants aged 15–65 with type 1 diabetes completed the self-report measures of the DAS-1, which includes clinical and psychological variables. Results: Robust confirmatory factor analysis detected a unidimensional structure of the item scores. The omega coefficient was 0.91 and test–retest reliability was 0.87. Classifying subjects as in a Positive or Negative mood state, ROC analysis yielded an optimal cut-off of 50 for the DAS-1 scores, with a clinical accuracy of AUC = 0.85. The DAS-1 demonstrated evidence of good reliability and acceptable construct validity. Conclusion: The DAS-1 demonstrated good clinical utility, good sensitivity and adequate specificity. Clinical and theoretical implications of these results are discussed.engVoRhttp://creativecommons.org/licenses/by/4.0/Type 1 diabetesAdjustment scaleAssessmentRobust factor structureReliabilityValidityDiabetes mellitus tipo 1AutoevaluaciónFecha de caducidad de productosEstudio de validaciónHumansReproducibility of ResultsDiabetes Mellitus, Type 1ROC CurveArea Under CurveSelf ReportFactor Analysis, StatisticalAttribution 4.0 International3237299710.3389/fpsyg.2020.005331664-1078Frontiers in Psychologyopen access
