其他摘要 | Background: Traumatic events have a profound impact on individuals, there are different theoretical hypotheses about the relationship between posttraumatic stress disorder (PTSD) and posttraumatic growth (PTG), the most common and specific responses following traumatic events. Within the population of children and adolescents, who are particularly susceptible to the influences of traumatic events, all those hypotheses are supported by different empirical evidence, yet the associated findings remain inconclusive.
Methods: Current research systematically examined the relationship between PTSD and PTG among children and adolescents based on two different perspectives, variables and people heterogeneity, and investigated the sources of heterogeneity in their relationship. The research encompassed: (1) Meta-analysis of the robust relationship between cross-sectional PTSD and PTG, (2) Cross-lagged analysis was used to calculate influence of PTSD and PTG on each other's level, (3) Latent growth modeling was used to analysis the influence of PTSD and PTG on each other's development rate, (4) Latent profile analysis was used to calculate the combined of PTSD and PTG, (5) Latent transition analysis was used to assess the transformation between combined groups of PTSD and PTG, (6) Latent growth mixture modeling was used to analysis the development of PTSD and PTG, (7) Multi-process growth mixture modeling was used to analysis the combined trajectories of PTSD and PTG. The meta-analysis followed the PRISMA standards and searched multiple databases such as Scopus, Web of Science and PubMed. The empirical studies use data from the survey of 699 children and adolescents(mean age 12.2, SD=2.3, range:8-17)who experienced the "8·12" Tianjin Port explosion incident, at 4 months, 8 months and 13 months after the explosion.
Results: The meta-analysis, which synthesized findings from 28 articles (involving 18,816 participants) in existing literature, revealed a positive cross-sectional correlation between PTSD and PTG (r=0.129, 95% CI: 0.063; 0.195). In empirical studies, PTSD and PTG were positively correlated at all three different time points. Cross-lagged panel analysis demonstrated that earlier levels of PTSD could predict later levels of PTG, but not vice versa. Latent growth modeling indicated that initial levels of PTSD could predict the rate of change in PTG, whereas the reverse was not supported. Latent profile analysis revealed three population heterogeneity patterns: "Growth Group," "High Symptom Group," and "Psychological Resilience Group." Latent transition analysis suggested that individuals may transition between these groups over time. Latent growth mixture modeling identified two population heterogeneity trajectories of PTSD: "Symptom Escalation Group" and "Resilience Recovery Group." Conversely, in the PTG development trajectory, three population heterogeneity trajectories emerged: "Stable Group," "Low Growth Decline Group," and "Continued High Growth Group," with initial severity levels of PTSD symptoms predicting the PTG trajectories, while the reverse was not supported. Multi-process growth mixture modeling uncovered three population heterogeneity groups in the combined developmental model of both constructs: "Symptom Feature Group," "Resilience Feature Group," and "Growth Feature Group," each demonstrating differences in developmental levels and rates of change, the intensity of trauma exposure can predict the classification of some heterogeneous groups. |
