Depression, Anxiety and Stress Scales (DASS-21): Factor structure, reliability, invariance and validity of the Catalan Version

The aim of this study was to analyse the evidence of validity, invariance and reliability of the Catalan version of the 21-item Depression, Anxiety and Stress Scale (DASS-21), using the confirmatory factor analysis (CFA) and exploratory structural equation modelling (ESEM) approach. Then, to reasses...

Then, to reassess the best structure obtained in a different validation sample. The items tested correspond to those in the original version of the DASS-21, after transcultural adaptation. The questionnaire was applied to a non-clinical sample of adults (n= 716), of both sexes and a mean age of 40.94 years (SD= 15.21). For study, the sample was randomly-split into two groups: calibration sample, and cross-validation sample. In first subsample nine models were tested. As the first-order three-factor CFA model was the most parsimonious, with well-defined factors that were also supported in terms of their reliabilities (α and ω) and validities, it was selected as the preferred model. The invariance between genders was tested using the total sample. Considering all findings, the Catalan version of DASS-21 is invariant, reliable and shows construct validity, making it a suitable instrument for use in research in the Catalan adult population.El objetivo de este estudio fue analizar la validez, invarianza y fiabilidad de la versión catalana de la Escala de Depresión, Ansiedad y Estrés de 21 ítems (DASS21-) utilizando un enfoque basado en el análisis factorial confirmatorio (CFA) y el análisis exploración de ecuaciones de modelos estructurales (ESEM), para, seguidamente, reevaluar la mejor estructura obtenida en una muestra de validación diferente. Los ítems ensayados se corresponden con los de la versión original del DASS-21, previa adaptación transcultural. El cuestionario se aplicó a una muestra no clínica de adultos (n = 716) de ambos sexos y una edad media de 40,94 años (DE = 15,21). Para el estudio, la muestra se dividió aleatoriamente en dos grupos: muestra de calibración y muestra de validación cruzada. En la primera submuestra se probaron nueve modelos. Se seleccionó el modelo CFA de tres factores de primer orden por ser el más parsimonioso, con factores bien definidos que también estaban respaldados en términos de confiabilidad (α y ω) y validez. La invariancia entre géneros se probó utilizando la muestra total. Considerando todos los hallazgos, la versión catalana de DASS-21 es invariante, confiable y muestra validez de constructo; por tanto, es un instrumento adecuado para su uso en investigación en población adulta catalana.Universitat de Barcelona2022info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionhttps://doi.org/10.1344/ANPSIC2022.52/3.4https://hdl.handle.net/10459.1/465330reponame:Recercat.
