Psychiatry Res. 2017 Oct;256:312-317http://hdl.handle.net/10668/11361The aim of the study was to determine the criterion validity of a computerized version of the General Anxiety Disorder-7 (GAD-7) questionnaire to detect general anxiety disorder in Spanish primary care centers. A total of 178 patients completed the GAD-7 and were administered the Composite International Diagnostic Interview (CIDI) for DSM-IV Axis I Disorders, which was used as a reference standard. Sensitivity, specificity, positive and negative predictive values, and positive and negative likelihood ratios were calculated. A cut-off of 10 yielded a sensitivity of .87, a specificity of .78, a positive predictive value of .93, a negative predictive value of .64, a positive likelihood ratio of 3.96 a negative likelihood ratio of .17 and Younden's Index of .65. The GAD-7 performed very well with a cut-off value of 10, the most frequently used cut-off point. Thus, a computerized version of the GAD-7 is an excellent screening tool for detecting general anxiety disorder in Spanish primary care settings.enAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Computerized instrumentsCriterion validityGAD-7Generalized anxiety disorderPrimary careScreeningAdolescentAdultAgedAnxiety disordersDiagnostic and statistical manual of mental disordersFemaleHealth surveysHumansMaleMass screeningMiddle agedPredictive value of testsPrimary health carePsychological testsReference valuesReproducibility of resultsSensitivity and specificitySpainSurveys and questionnairesYoung adultScreening for generalized anxiety disorder in Spanish primary care centers with the GAD-7.research article28666201open accessAtención primaria de saludEncuestas epidemiológicasPruebas psicológicasReproducibilidad de los resultadosSensibilidad y especificidadTamizaje masivoTrastornos de ansiedadValor predictivo de las pruebasValores de referencia10.1016/j.psychres.2017.06.0231872-7123http://helvia.uco.es/xmlui/bitstream/10396/14896/1/moriana.pdf
