    El crecimiento postraumático es la capacidad psicológica para percibir cambios positivos ante eventos altamente estresantes o potencialmente traumáticos y puede ser especialmente útil para amortiguar sus efectos en la vida de los adolescentes. El objetivo de este estudio fue evaluar las propiedades psicométricas de la adaptación peruana del “Inventario de crecimiento postraumático” (PTGI). Participaron 2103 adolescentes (50,7% hombres) de entre 13 y 19 años, quienes estuvieron expuestos a algún evento altamente estresante en los últimos cinco años. Se realizó un análisis factorial confirmatorio, invarianza factorial, análisis de red y se correlacionó el PTGI con una medida de bienestar. Se observó el mejor ajuste parsimonioso en un modelo unidimensional de 21 ítems, el PTGI mostró ser invariante según el sexo, el análisis de red determinó mayor medida de centralidad de fuerza en el ítem 2 (apreciación de la vida). Estos resultados indican que el PTGI es una prueba con validez de constructo, invariante, fiable y adecuado para evaluar el nivel de crecimiento psicológico en adolescentes peruanos que sufrieron algún evento estresante durante los últimos cinco años.

    Posttraumatic growth is the psychological capacity to perceive positive changes in the face of highly stressful or potentially traumatic events and may be especially useful in buffering their effects in the lives of adolescents. The aim of this study was to evaluate the psychometric properties of the Peruvian adaptation of the Posttraumatic Growth Inventory (PTGI). A total of 2103 adolescents (50.7% male) between 13 and 19 years of age, who were exposed to some highly stressful event in the previous five years, participated in the study. Confirmatory factor analysis, factorial invariance, network analysis and correlation of the PTGI with a measure of well-being were performed. The best parsimonious fit was observed in a 21-item unidimensional model, the PTGI was shown to be gender invariant, and network analysis determined a greater measure of strength centrality in item 2 (appreciation of life). These results indicate that the PTGI is a test with construct validity, invariant, reliable and adequate to evaluate the level of psychological growth in Peruvian adolescents who suffered some stressful event during the previous five years.
