Core belief challenge and rumination as predictors of PTSD and PTG among adolescent survivors of the Wenchuan earthquake

Middle school students in Wenchuan County (N = 354) were assessed 4.5 years after the Wenchuan earthquake to examine the effects of challenges to core beliefs, intrusive rumination, and deliberate rumination on posttraumatic stress disorder (PTSD) and posttraumatic growth (PTG). The results indicated that intrusive rumination partly mediated the relationship between challenges to core beliefs and PTSD, whereas deliberate rumination partly mediated both the relationship between challenges to core beliefs and PTG, as well as the relationship between intrusive rumination and PTG. These findings suggest that challenges to core beliefs had a direct positive impact on both PTSD and PTG. Moreover, such challenges predicted PTSD through intrusive rumination and predicted PTG through deliberate rumination. Furthermore, intrusive rumination might cue individuals to engage in a more purposive deliberate rumination process. These results indicate that PTSD and PTG are influenced by different mechanisms and that PTSD and PTG represent 2 separate dimensions of experience following adversity.

Longitudinal relationships between posttraumatic stress symptoms and sleep problems in adolescent survivors following the Wenchuan earthquake in China.

Purpose To examine the longitudinal relationships between Posttraumatic Stress Disorder (PTSD) and sleep problems among adolescent survivors in the Wenchuan earthquake, China. Methods 350 adolescent survivors were randomly selected from several primary and secondary schools in the counties of Wenchuan and Maoxian, the two areas most severely affected by the Wenchuan earthquake. Participants completed Revised Child PTSD Symptom Scale and Sleep Problems Subscale of Self-generated Child Behavior Problems Questionnaire at one year (T1), one-and-a-half years (T2), two years (T3) after the earthquake, respectively. Results There was a bidirectional relationship between intrusive symptom clusters of PTSD and sleep problems from T1 to T2, and this relationship became non-significant from T2 to T3. There was a one-way predictive relationship of avoidance symptom clusters of PTSD onto sleep problems from T1 to T3. The hyperarousal symptom clusters of PTSD had effects on sleep problems from T1 to T2 but not from T2 to T3, while sleep problems have no significant effect on hyperarousal symptom clusters of PTSD from T1 to T3. In addition, the relationships between three symptom clusters of PTSD and sleep problems weakened with time change. Conclusions From 1 year to 1.5 years after the earthquake, all the three symptom clusters of PTSD could be important predictive factors for the development and maintenance of sleep problems, while sleep problems could only be risk factors for the intrusive symptom clusters of PTSD. From 1.5 years to 2 years, only the avoidance symptom clusters of PTSD were risk factors for sleep problems, and sleep problems had no significant effects on any symptom clusters of PTSD. Overall, the relationship between PTSD and sleep problems weakened with time change.

Longitudinal linkages between posttraumatic stress disorder and posttraumatic growth in adolescent survivors following the Wenchuan earthquake in China: A three-wave, cross-lagged study

The aim of this study is to examine the longitudinal relationships between posttraumatic stress disorder (PTSD) and posttraumatic growth (PTG) among adolescent survivors of the 2008 Wenchuan earthquake in China. The participants in our study included 245 adolescent survivors who were randomly selected from several primary and secondary schools in the counties of Wenchuan, which are the areas most severely affected by the Wenchuan earthquake. Participants completed the Revised Child PTSD Symptom Scale and the Posttraumatic Growth Inventory (PTGI) at 3.5 years after the earthquake (T1), 4.5 years after the earthquake (T2), and 5.5 years after the earthquake (T3). The results found that PTSD reported in T1 and T2 predicted subsequent PTG reported at T2 and T3 and that PTG did not predict PTSD from T1 to T3. In addition, the cross-sectional correlation between PTSD and PTG weakened from T1 to T3. These results indicate that PTSD and PTG can coexist in individuals after a traumatic experience, and they further suggest that the reduction in PTSD does not indicate the appearance of PTG.

The role of rumination in posttraumatic stress disorder and posttraumatic growth among adolescents after the wenchuan earthquake

Three hundred and seventy-six middle school students in Wenchuan County were assessed three and one-half years after the Wenchuan earthquake to examine the effects of rumination on posttraumatic stress disorder (PTSD) and posttraumatic growth (PTG). The results revealed that recent intrusive ruminations partly mediated the relationship between intrusive rumination soon after the earthquake with PTSD but not with PTG. Recent deliberate rumination partly mediated the relationship between intrusive rumination soon after the earthquake and PTG but not PTSD. Moreover, recent deliberate rumination also partly mediated the relationship between recent intrusive rumination with PTG but not with PTSD. Overall, intrusive rumination soon after the earthquake had an effect on PTSD but not on PTG through recent intrusive rumination and affected PTG but not PTSD through deliberate recent rumination. Furthermore, intrusive rumination soon after the earthquake affected PTG but not PTSD by recent deliberate rumination following recent intrusive rumination. More importantly, the present study also found that PTSD exhibited no relation to PTG. These results suggest that PTSD and PTG are influenced by different mechanisms, which further indicates that PTSD and PTG represent two separate dimensions of experience after adversity.

Longitudinal relationships between neuroticism, avoidant coping, and posttraumatic stress disorder symptoms in adolescents following the 2008 Wenchuan earthquake in China

The Wenchuan earthquake, which occurred in southwestern China in May 2008, was a source of severe psychological distress to adolescents. This study explored the developmental trajectory of posttraumatic stress disorder (PTSD) symptoms and the longitudinal relationships between neuroticism, avoidant coping, and PTSD symptoms measured at three time points: 1 year (T1), 1.5 years (T2), and 2 years (T3) after the earthquake. The participants included 636 adolescents from several high schools located in the areas that were most severely affected by the earthquake. Structural equation modeling results revealed bidirectional effects between neuroticism, avoidant coping, and PTSD symptoms. More severe PTSD symptoms predicted higher levels of avoidant coping at T1–T2 and T2–T3 but only predicted higher levels of neuroticism at T1–T2. Higher levels of neuroticism at T1 predicted more severe PTSD symptoms at T1–T2, while higher levels of avoidant coping at T1 predicted more severe PTSD symptoms at T2–T3.

Understanding the Relationship Between Social Support and Posttraumatic Stress Disorder/Posttraumatic Growth Among Adolescents After Ya'an Earthquake: The Role of Emotion Regulation.

Objective: Posttraumatic distress disorder (PTSD) and posttraumatic growth (PTG) may coexist in trauma survivors, but there are mixed relationships between PTSD and PTG. To elucidate their relationship and constructs, it is necessary to examine simultaneously predictive factors, and to compare their determining factors. The aim of this study was to increasing our understanding the relationship between PTSD and PTG by examining simultaneously the role of social support and emotion regulation in PTSD and PTG among adolescents after the earthquake. Methods: Six months after the Ya’an earthquake, 315 middle school students in Lushan county were assessed using measures of trauma exposure, social support, and emotion regulation, as well as Child PTSD Symptom Scale and Posttraumatic Growth Inventory. Results: Social support had significant direct association with PTG but not with PTSD, but social support had a negative indirect prediction on PTSD and a positive indirect prediction on PTG through cognitive reappraisal. Social support, through expressive suppression, had a significant and indirect prediction on PTSD, but a nonsignificant indirect prediction on PTG. Conclusions: This study indicate that the predictive mechanism of PTSD and PTG were different and further suggest that PTSD and PTG are separate, independent dimensions of psychological experiences following adversity.

Longitudinal relationships between gratitude, deliberate rumination, and posttraumatic growth in adolescents following the Wenchuan earthquake in China.

To examine the longitudinal relationship between gratitude, deliberate rumination and posttraumatic growth (PTG) in the adolescent survivors after the Wenchuan earthquake, 217 adolescent survivors were randomly selected from several primary and secondary schools in the county of Wenchuan, and were assessed by questionnaires at three and a half years (T1), four and a half years (T2), five and a half years (T3) after the Wenchuan earthquake, respectively. The results found that there was a one-way predictive relationship of gratitude onto PTG from T1 to T3, and gratitude predicted deliberate rumination from T1 to T2 but not T2 to T3. Deliberate rumination only had a significant positive effect on PTG from T2 to T3, and PTG only predicted deliberate rumination from T1 to T2. These results indicated that gratitude could be a stable predictive factor for the development of PTG, and gratitude could also affect PTG by deliberate rumination. In addition, the predictive effect between deliberate rumination and PTG is unstable with time change.

The reciprocal relationship between compounding awareness and vocabulary knowledge in Chinese: a latent growth model study

The aim of this study is to examine the developmental relationship between compounding awareness and vocabulary knowledge from grades 1 to 2 in Chinese children. In this study, 149 Chinese children were tested on compounding awareness and vocabulary knowledge from Time 1 to Time 4, with non-verbal IQ, working memory, phonological awareness, orthographical awareness, and rapid automatized naming at Time 1 as control variables. Latent growth modeling was conducted to analyze the data. Univariate models separately calculated childrens initial levels and growth rates in compounding awareness and vocabulary knowledge. Bivariate model was used to examine the direction of the developmental relationships between the two variables with other cognitive and linguistic variables and the autoregression controlled. The results demonstrated that the initial level of compounding awareness predicted the growth rate of vocabulary knowledge, and the reverse relation was also found, after controlling for other cognitive and linguistic variables and the autoregression. The results suggested a reciprocal developmental relationship between childrens compounding awareness and vocabulary knowledge for Chinese children, a finding that informs current models of the relationship between morphological awareness and vocabulary knowledge.

The role of posttraumatic fear and social support in the relationship between trauma severity and posttraumatic growth among adolescent survivors of the Yaan earthquake.

Middle school students in Lushan county (Nu2009=u2009315) were assessed 6 months after the Yaan earthquake using a trauma severity questionnaire, a posttraumatic fear questionnaire, a social support questionnaire and a posttraumatic growth inventory to examine the effects of posttraumatic fear and social support in the relationship between trauma severity and posttraumatic growth (PTG). The results showed that posttraumatic fear mediated the relationship between trauma severity and PTG, and social support moderated the relationship between posttraumatic fear and PTG. These findings suggested that trauma severity could be positively associated with PTG in a direct way or in an indirect way through posttraumatic fear. Moreover, posttraumatic fear had a positive relation to PTG under the condition of high social support level, whereas the relation was non-significant when the level of social support was low. These results were discussed in terms of their implications for adolescents after trauma.

Self-esteem and hope mediate the relations between social support and post-traumatic stress disorder and growth in adolescents following the Ya’an earthquake

ABSTRACT Background and objective: Although posttraumatic stress disorders (PTSD) and posttraumatic growth (PTG) can co-exist, and several theories suggest that social support, self-esteem, and hope can predict both PTSD and PTG, no study to date has examined the combined role of social support, self-esteem, and hope in PTSD and PTG. The present study aimed to simultaneously examine the mediating roles of self-esteem and hope in the relations between social support and PTSD, and between social support and PTG. Design: This study included 397 adolescents living in Lushan County, China, who were affected by the Ya’an earthquake. Method: The participants completed the self-report questionnaires at two and a half years after the earthquake. Structural equation models were built to examine the roles of social support, self-esteem, and hope in PTSD and PTG. Results: Social support directly and negatively predicted PTSD and positively predicted PTG. Moreover, social support negatively predicted PTSD via self-esteem, and positively predicted PTG via hope. In addition, social support positively predicted PTG through multiple mediating paths from self-esteem to hope. Conclusions: PTSD and PTG had different predictive paths. Specifically, social support reduced PTSD through enhanced self-esteem and promoted PTG through hope, or through the path from self-esteem to hope.
