- W3045071491 abstract "While self-reported post-traumatic growth (PTG) has been documented after a wide variety of potentially traumatic experiences, we need more knowledge on the mechanisms behind PTG to gain a better understanding of this phenomenon.We aimed to investigate the hypothesized mechanism of perceived event centrality as a mediator on the pathway between peritraumatic reactions and later PTG.In total, 204 survivors of the 2011 massacre on Utøya island, participated 4-5 months (T1), 14-15 months (T2), and 30-32 months (T3) post-terror. We applied counterfactually based causal mediation analysis to explore the potential mediating role of survivors' perceived centrality (T2) in linking their peritraumatic reactions (T1) and self-reported PTG (T3).The vast majority of the survivors reported experiencing some positive changes post-terror, and we found a positive, significant association between survivor's peritraumatic reactions, perceived event centrality and self-reported growth. However, we did not find that centrality significantly mediated the longitudinal association between peritraumatic reactions and later PTG.Reports of PTG are common post-terror, and peritraumatic reactions and perceptions of centrality may help explain individual differences in trauma survivors' level of PTG. Perceived event centrality about one year post-trauma does not appear to explain the relationship between initial reactions to trauma and subsequent PTG.Antecedentes: Si bien el crecimiento postraumático (CPT) auto-reportado se ha documentado después de una amplia variedad de experiencias potencialmente traumáticas, necesitamos más conocimiento sobre los mecanismos detrás del CPT para obtener una mejor comprensión de este fenómeno.Objetivo: Nuestro objetivo fue investigar el mecanismo hipotético de la centralidad percibida del evento como mediador en la vía entre las reacciones peritraumáticas y el CPT posterior.Método: En total, 204 sobrevivientes de la masacre de 2011 en la isla de Utoya, participaron 4-5 meses (T1), 14-15 meses (T2) y 30-32 meses (T3) después del ataque terrorista. Aplicamos un análisis de mediación causal contrafactual para explorar el posible papel mediador de la centralidad percibida (T2) de los sobrevivientes al vincular sus reacciones peritraumáticas (T1) y el CPT autoinformado (T3).Resultados: La gran mayoría de los sobrevivientes informaron haber experimentado algunos cambios positivos después del ataque terrorista, y encontramos una asociación positiva y significativa entre las reacciones peritraumáticas del sobreviviente, la centralidad del evento percibido y el crecimiento autoinformado. Sin embargo, no encontramos que la centralidad mediara significativamente la asociación longitudinal entre las reacciones peritraumáticas y el CPT posterior.Conclusión: Los reportes de CPT son comunes después del terrorismo, y las reacciones peritraumáticas y las percepciones de centralidad pueden ayudar a explicar las diferencias individuales en el nivel de CPT de los sobrevivientes de trauma. La centralidad percibida del evento aproximadamente un año después del trauma no parece explicar la relación entre las reacciones iniciales al trauma y el CPT posterior.背景: 虽然在大量潜在的创伤经历之后记录了自我报告的创伤后成长 (PTG), 但我们需要更多有关PTG背后机制的知识, 以更好地了解这一现象。目的: 我们旨在调查事件中心性作为围创伤反应与后来的PTG之间通路的中介变量的假设机制。方法: 总共有204名经历2011年Utoya岛大屠杀幸存者在恐怖活动后的4-5个月 (T1), 14-15个月 (T2) 和30-32个月 (T3) 参加了研究。我们应用了基于反事实 (counterfactually) 的因果中介分析, 以探索幸存者感知到的事件中心性 (T2) 对围创伤反应 (T1) 和自我报告的PTG (T3) 之间关系的潜在中介作用。结果: 绝大多数幸存者报告说恐怖袭击后经历了一些积极变化。我们发现幸存者的围创伤反应, 感知的事件中心性和自我报告的PTG之间存在积极的显著关联。然而, 我们没有发现中心性显著中介围创伤反应与后来的PTG之间的纵向联系。结论: PTG的报告在恐怖袭击后很常见, 创伤前后的反应和对中心性的理解可能有助于解释创伤幸存者PTG水平的个体差异。但创伤后一年左右的事件中心性似乎不能解释创伤初期反应与随后的PTG之间的关系。." @default.
