Resumo: | We conducted an exploratory factor analysis (EFA) to empirically derive the COVID-19 Peritraumatic Distress Index (CPDI) factor structure. Data (peri-traumatic stress during the COVID-19). We used data from the Physical and Psychological Reactions as Health Indicators Research (Virtual Laboratory of Affective, Cognitive and Behavioral Neuropsychometry – LAVINACC). EFA was implemented using a Polychoric Matrix and Robust Diagonally Weighted Least Squares (RDWLS) extraction method. We used the Parallel Analysis with random permutation, and as a rotation technique, we used the Robust Promin. The adequacy of the model was evaluated using the Root Mean Square Error of Approximation (RMSEA), Tucker-Lewis Index (TLI), and Comparative Fit Index (CFI) fit indices. The Ratio Communality Index (RCI) reported (RCI = 0.998452) showed both subsamples have a similar amount of common variance. Results showed adequacy of the polychoric correlation matrix measured by Bartlett's sphericity (21116.6, (df = 276; p < 0.00001) and KMO = 0.939. The overall assessment (UniCo = 0.918; ECV = 0.85), MIREAL = 0.200), suggested that CPDI can be treated as a two-factor structure: first factor (internal stressors), second factor (external stressors). Replication studies to verify further validity and reliability should be undertaken. |

Se utilizaron datos de la Investigación sobre Reacciones Físicas y Psicológicas como Indicadores de Salud (Laboratorio Virtual de Neuropsicometría Afectiva, Cognitiva y Conductual – LAVINACC). El EFA se implementó utilizando un método de extracción de matriz policórica y mínimos cuadrados ponderados diagonalmente robustos (RDWLS). Se utilizó el Análisis Paralelo con permutación aleatoria, y como técnica de rotación se utilizó Promin. La idoneidad del modelo se evaluó utilizando los índices de ajuste Raíz del error cuadrático medio de aproximación (RMSEA), Índice de Tucker-Lewis (TLI) e Índice de ajuste comparativo (CFI). El índice de similitud (RCI) informado (RCI = 0.998452) mostró que ambas submuestras tienen una cantidad similar de varianza común. Los resultados mostraron adecuación de la matriz de correlación policórica medida por la esfericidad de Bartlett (21116.6, (df = 276; p < 0.00001) y KMO = 0.939. La evaluación global (UniCo = 0.918); (ECV = 0.85), MIREAL = 0.200), sugirió que el CPDI puede ser tratado como una estructura de dos factores: primer factor (estresores internos), segundo factor (estresores externos). Se deben realizar estudios de replicación para verificar una mayor validez y confiabilidad.Realizamos uma análise fatorial exploratória (EFA) para derivar empiricamente a estrutura fatorial do Índice de Estresse Peri-traumático COVID-19 (CPDI).
