Resumen
A pesar de que el inventario de crecimiento postraumático (PTGI) es un instrumento ampliamente utilizado para evaluar los cambios positivos después de un trauma, su estructura factorial no ha sido consistente en las validaciones hechas al español. Actualmente, no se cuenta con evidencia del estudio de sus propiedades psicométricas en población mexicana, por lo que el propósito de este estudio fue contrastar la estructura factorial del PTGI y describir el perfil promedio de crecimiento postraumático en una muestra mexicana. Participaron 446 personas con edades de 18 a 77 años víctimas de distintos eventos traumáticos. Los resultados indicaron una solución unifactorial, la cual mostró adecuada bondad de ajuste y confiabilidad excelente (α = .94). De acuerdo al perfil de los participantes, se identificó un cambio promedio en el crecimiento, no encontrándose diferencias entre mujeres y hombres. El PTGI-MX se considera un instrumento con buenas propiedades psicométricas para evaluar el crecimiento después de un evento traumático en población mexicana.
Abstract
Although the post-traumatic growth inventory (PTGI) is a widely used instrument to assess positive changes after trauma, its factor structure has not been consistent in the validations made in Spanish. Currently, there is no evidence of the study of its psychometric properties in Mexican population, so the purpose of this study was to contrast the factor structure of the PTGI and describe the average profile of post-traumatic growth in a Mexican sample. The sample consisted in 446 people aged 18 to 77 years, victims of different traumatic events. The results showed a unifactorial solution, which showed adequate goodness of fit and excellent reliability (α = .94). A moderate change in growth was identified, being equivalent according to sex. The PTGI-M is considered an instrument with good psychometric properties to evaluate growth after a traumatic event in Mexican population.
