          Abstract

          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.

          The Posttraumatic Growth Inventory: measuring the positive legacy of trauma.

          The development of the Posttraumatic Growth Inventory, an instrument for assessing positive outcomes reported by persons who have experienced traumatic events, is described. This 21-item scale includes factors of New Possibilities, Relating to Others, Personal Strength, Spiritual Change, and Appreciation of Life. Women tend to report more benefits than do men, and persons who have experienced traumatic events report more positive change than do persons who have not experienced extraordinary events. The Posttraumatic Growth Inventory is modestly related to optimism and extraversion. The scale appears to have utility in determining how successful individuals, coping with the aftermath of trauma, are in reconstructing or strengthening their perceptions of self, others, and the meaning of events.

              A meta-analytic review of benefit finding and growth.

              The authors conducted a meta-analysis to examine the relations of benefit finding to psychological and physical health as well as to a specific set of demographic, stressor, personality, and coping correlates. Results from 87 cross-sectional studies reported in 77 articles showed that benefit finding was related to less depression and more positive well-being but also more intrusive and avoidant thoughts about the stressor. Benefit finding was unrelated to anxiety, global distress, quality of life, and subjective reports of physical health. Moderator analyses showed that relations of benefit finding to outcomes were affected by the amount of time that had passed since stressor onset, the benefit finding measured used, and the racial composition of the sample.
