Abstract

Background

The study was implemented to examine the relationship between traumatic experiences and longitudinal development of mental health for children and adolescents who survived the 2008 Sichuan earthquake.

Methods

Using the method of multistage systematic sampling, 596 children aged between 8 and 16 years were randomly selected from severely affected areas of the earthquake. These children were interviewed with standardized instruments of posttraumatic stress disorder (PTSD) and depression at the 15th month after the earthquake, and re-interviewed at the 36th month.

Results

From the initial to the follow-up assessments, there were no significant changes in both PTSD and depression scores. In addition, no significant change was found on the overall prevalence rates of the symptoms: from 12.4% to 10.7% for PTSD, from 13.9% to 13.5% for depression, and from 4.2% to 4.7% for their co-occurrence. The study also indicated that the earthquake might have a delayed impact on the psychosocial functioning of children and adolescents who were not directly affected by the disaster.

Conclusions

For child and adolescent survivors of the earthquake, symptoms of PTSD and depression seemed to persist over time. The finding that children reduced their use of mental health services raised great concerns over how to fulfill the unmet psychological needs of these children. More mental health interventions should be allocated to children who had elevated risk for developing persistent course of the symptoms.

Peer Review reports

Background

Over the past decade, Asia has been the continent frequently and severely affected by earthquakes [1]. From the 225,000 deaths caused by the 2004 Indian Ocean earthquake and tsunami [2], to 73,276 deaths by the 2005 Pakistan earthquake [3], 69,200 deaths by the 2008 China Sichuan earthquake [4], and 15,839 deaths by the 2011 Great East Japan earthquake [5], Asian countries suffered not only giant losses from the instantaneous and devastating blow of the disaster, but critical consequences from the longstanding post-earthquake adversities, e.g., the dysfunction of public health systems. As an essential component of public health, continuing attention should be paid to the mental health of the survivors because psychological impact may last for many years after the event [6–9]. However, little research has prospectively examined the psychological sequelae in Asian socioeconomic context, especially for children and adolescents.

There are theoretical and practical reasons to explore this issue. On one hand, empirical literature on the association between children’s disaster-related traumatic experiences and mental health mostly drew samples from schools [8, 10–14]. This sampling method, however, is not suitable for research conducted in low-income settings of Asia, where there is a reported substantial proportion of school-aged children dropouts [15, 16]. In addition, most of the longitudinal studies conducted in Asia were accomplished in a short time period, often in a year or several months [17, 18], which might result in the underrepresentation of psychological development in the subjects. In the study we adopted a community-based design, an approach that is increasingly used to examine the environmental and social determinants of health [19], so that we could assess the psychological development of child survivors in a two-year period. Certainly, this research would enrich the literature of post-disaster studies in Asia. On the other hand, as psychological support is an indispensible investment to prevent mental health crisis after natural disasters, it would be beneficial to screen out children with certain characteristics that are associated with vulnerability to psychological symptoms, so that appropriate and cost-effective interventions would be allocated to them.

Therefore, by a community-based follow-up design, this study aimed to investigate the relationships between various traumatic experiences and the longitudinal development of Posttraumatic Stress Disorder (PTSD) and depression among child and adolescent survivors of the 2008 Sichuan earthquake.

Methods

Subjects and design

Two assessments were carried out among child and adolescent survivors, 15 and 36 months after the earthquake. A household was used as the primary sampling unit and was defined as any group of persons who lived together and shared food and bedding, etc. Before sampling, a power analysis to determine an appropriate sample size was based on symptoms of PTSD. Since the literature showed that the post-disaster prevalence rates of PTSD varied between 10% and 22% among East-Asia children [11, 14, 18], 10% was used to calculate the sample size as a conservative approach. Assuming a design effect of 1.5, we estimated that 576 participants were required to obtain 3.0% precision around the prior-specified 10% prevalence rate of PTSD. The final anticipated sample size was adjusted to 1,145 households, after considering the proportion of households with a child from 8 to 16 years of age and a potential 20% non-response rate.

The study employed a multi-stage systematic sampling design to select participants in the severely affected areas of the earthquake. Details of the sampling procedure were depicted in Figure 1. In brief, two of the ten severely earthquake-affected sub-districts declared by the government, including 267 villages and over 65,900 households, were selected as the frame. After excluding villages with a very small number of households and villages with possible geological dangers, such as landslide, 39 villages were used as potential sampling sites. Within each available village, systematic sampling was performed. Households were numbered according to registration information and were systematically selected. But for a number of villages where many people no longer resided at their homes, systematic sampling was not feasible; non-random sampling methods were supplemented. Finally, a total of 1,170 households were recruited, which included 690 families with at least one child aged between 8 and 16 years.

Data collection

Our psychologists and eight social science graduate students performed the interview. Before the assessments, interviewers were called together to review the questionnaire and achieve agreement on the explanation of each item. Exclusion criteria were absence from the affected area during the earthquake and severe learning deficiency. With the help from key informants (e.g., parents, adult neighbors, school teachers, etc.), children and adolescents with pre- or post-earthquake traumatic experiences were also excluded. When more than one child was eligible for study in a household, one child was selected according to the Kish method [20]. With the help of village, township and county-level school staff, we identified the children who were present at school at the time of the home visit. Due to the high illiteracy rate in the surveyed area, only verbal consents were sought from their guardians and then carefully recorded by the interviewers in field files after standard and complete descriptions of the study. Then each participant completed the questionnaire independently, and was presented a small gift upon its completion. A week later, almost ten percent of participants who were originally involved in the questionnaire interview were reassessed by our psychologists based on DSM-IV criteria.

Instruments

Standardized instruments were used to measure the severity of PTSD and depression in the subjects. Symptoms of PTSD were evaluated using the self-report Child PTSD Reaction Index [21, 22]. The instrument has been frequently used to assess traumatized children after major disasters and catastrophic violence, and has satisfactory psychometric properties in a Chinese context [4]. It contains 20 items rated on a 5-point Likert scale ranging from 0 (“none”) to 4 (“most of the time”), making the total score of the Child PTSD Reaction Index ranging from 0 to 80. Comparisons of Child PTSD Reaction Index scores with clinical diagnosis of PTSD have suggested the following guidelines: (1) 0–11 = suspect, 12–24 = mild, 25–39 = moderate, 40–59 = severe, 60–80 = very severe; (2) high level of agreement between a score > = 40 and diagnosis of PTSD based on DSM-IV criteria [22].

The Children’s Depression Inventory (CDI), which has been widely used to measure depression in children and adolescents in epidemiological studies [23, 24], was employed to assess symptoms of depression among the participants. It contains 27 items with a self-rating scale ranging from 0 to 2 that yields a total score ranging from 0 to 54. Children with a score of 20 or above were classified as having symptoms of depression [24]. The instrument has been validated in Chinese children with Cronbach’s α ranging from 0.85 to 0.89, and test-retest reliability ranging from 0.75 to 0.85 [23, 25–27].

Perceived social support was measured by the adapted Multidimensional Scale of Perceived Social Support (MSPSS) [28, 29]. It contains 12 questions with a self-rating scale ranging from 0 to 4 that yields a total score ranging from 0 to 48. A Total MSPSS Score was obtained by summing across all items, with a higher score indicating more perceived social support. Hong and his colleagues have demonstrated its feasibility in China [30].

Adapted from an existing disaster exposure scale [10], the earthquake-related event exposure measure was the sum of 11 events that could occur during or after the earthquake. All these questions were coded into yes/no items, and were categorized into three groups: objective experience, earthquake-related loss, and subjective experience. Positive responses to these items were summed for analyses in each category. For mental health service utilization measures, we adopted the methodology of National Comorbidity Survey [31]. We asked participants whether they received counseling from a helping professional (e.g., psychologist, psychiatrist, physician, trained teacher, etc.) for emotional problems and whether the counseling was related to the earthquake.

To minimize potential bias, the questionnaire was verified for accuracy and comprehensibility by local mental health professionals. Questions that might be misunderstood were identified, and the best equivalent local expressions were used. The Ethics Committee of the Second Military Medical University approved the consent procedures and instruments used in the study.

Data analysis

Means, standard deviations, frequencies and percentages were calculated for descriptive data analysis. T-tests were used to evaluate differences in continuous variables, and Chi-square tests were used to test for significance in categorical characteristics. Point estimates and 95% confidence intervals (CI) for prevalence rates of PTSD and depression were estimated overall as well as stratified by demographics and earthquake-related experiences. Kappa coefficients were used to test the agreement on the instrument-based and DSM-IV-based clinical diagnosis of PTSD and depression. To examine the relationships between perceived social support and symptoms of PTSD and depression, Pearson correlations were computed. Linear regression analyses were performed to examine the relative contribution of each independent variable to the severity of PTSD and depression. These variables were selected either because they were associated with the symptoms, or because previous research and a priori theoretical judgment have indicated that they should be included in the models. Two-tailed p < 0.05 was considered statistically significant. Data were analyzed using SPSS version 17.0 (SPSS Inc, Chicago, Ill).

Results

A total of 596 participants were included in the initial assessment, with a response rate of 86.4% (596/690). In the follow-up assessment, 160 children were absent or couldn’t be located, and another 6 children refused to participate, hence only 430 children were retained in the follow-up assessment, which accounted for 72.1% (430/596) of the original sample. The sample at baseline consisted of 297 boys (49.8%) and 299 girls (50.2%) between the ages of 8 and 16 years, with mean (SD) age at 11.5 (2.1) and 11.4 (2.2) years, respectively. Compared with children from Wenchuan, those from Mao were more likely to report that they were in serious danger, that their houses had been seriously damaged, that they felt extremely anxious about their own lives, and that they felt scared that family members or significant others would die or be seriously injured (Table 1).

Empirically derived cutoff scores for both the Child PTSD Reaction Index and CDI were used to estimate the prevalence rates of PTSD and depression. High agreement was found between the instrument-based and DSM-IV-based clinical diagnosis of PTSD and depression, with Kappa coefficients at 89.8% and 91.2% in the initial assessment, and 87.5% and 89.5% in the follow-up assessment, respectively. In the study, the overall prevalence rates of the symptoms did not change significantly from the 15th to the 36th month: 12.4% to 10.7% for PTSD (χ2 = 0.71, df = 1; p = 0.40), from 13.9% to 13.5% for depression (χ2 = 0.04, df = 1; p = 0.84), and from 4.2% to 4.7% for co-occurrence of both symptoms (χ2 = 0.12, df = 1; p = 0.73). Figure 2 shows the prevalence rates of PTSD and depression among participants with various traumatic experiences, from which we can see that over 20% of children who had family members or friends seriously injured, had lost family members, or had lost significant others still faced symptoms of PTSD and depression even 36 months after the earthquake.

For both assessments, we found that girls scored significantly higher PTSD scores than boys; children who had witnessed someone being killed or seriously injured, had lost significant others, had lost important belongings, or had felt guilt concerning someone’s death or injury reported higher PTSD scores than those who had not (Table 2). From the 15th to the 36th month after the earthquake, the overall score for both PTSD and depression did not change significantly. But the situation differed, conditional on children’s demographics and traumatic experiences. Children living in Wenchuan experienced a marked decrease of depression score over the time, while children who were from Mao or were ethnic minorities reported increase of the score. Curiously, we found that children who were identified as not having been seriously injured, having lost family members, having lost significant others, or having felt guilt concerning someone’s death or injury reported an increase of PTSD score over time (Table 2).

In the study, we found that the proportion of participants who reported earthquake-related utilization of mental health services dropped substantially from 34.6% in the first 15 months to 9.5% in the follow-up period. And Pearson correlations demonstrated the positive role of perceived social support in mitigating the symptoms of PTSD (r = −0.10, p = 0.04) and depression (r = −0.42, p < 0.001). The role of social support in predicting PTSD was no longer significant when entering into the linear regression model with other variables, which is shown in Table 3. The strong correlation between PTSD and depression (r = 0.453; p < 0.001) made them serve as the biggest contributor for each other. A point increase in PTSD or depression was associated with more than 0.40-point increase in the other. As to the other variables, objective experiences, subjective experiences, and earthquake-related loss showed significant contributions to PTSD, while perceived social support showed marked influence on depression.

Discussion

By using a community-based follow-up study, we found that symptoms of PTSD and depression seemed to persist among child and adolescent survivors of the 2008 Sichuan earthquake, and that different traumatic experiences predicted different longitudinal development of PTSD and depression for these children. The study also indicated that the earthquake might have a delayed impact on the psychosocial functioning of children and adolescents who were not directly affected by the disaster.

The persistence of the symptoms could possibly be related to unremitting multiple post-disaster adversities that aggravated the symptoms or impeded their remission [9, 18]. Conversely, continued symptoms of PTSD and depression seemed to contribute to secondary stresses and adversities, such as disturbances in school and social functioning, which in turn imposed more difficulties for them to cope with the symptoms. Our study showed that children who had family members or friends seriously injured, had lost family members, or had lost significant others still faced higher prevalence of PTSD and depression than children with other traumatic experiences 36 months after the earthquake. The result may help to screen out children with an elevated risk for persistent psychological problems so that appropriate mental health interventions could be allocated to them.

However, the severity of PTSD differed from previous reports. A study among child survivors after the 1999 Chi-Chi earthquake in Taiwan indicated that victims near the epicenter had moderate levels of PTSD one year after the earthquake [32]; Goenjian et al., using Child PTSD Reaction Index, reported moderate reaction scores in bereaved adolescents six and a half years after the 1988 Spitak earthquake [9], and severe levels of PTSD in adolescents from three public schools six months after hurricane Mitch [33]. In contrast, our study found mild levels of PTSD. The differences may be attributed to different sampling frames. Our study was based on a large community-based sample, while previous studies primarily studied children with specific characteristics or in places with unique features (epicenter, etc.), which might result in a more severe estimation of PTSD symptoms.

A curious point deserves further notice, viz., children who were identified as not having been seriously injured, having lost family members, having lost significant others, or having felt guilt concerning someone’s death or injury reported an increase of PTSD score over the time. A possible speculation is that the earthquake, together with post-earthquake changes in social environment, had a delayed impact on the psychosocial functioning of children and adolescents who were not directly affected by the disaster. For example, while a child who lost his or her parent was likely to receive more support and care from families, relatives, friends and communities after the earthquake, a child without bereavement may get less help. Just as scarce mental health services may be especially allocated to children with more severe traumatic experiences while leaving children without a specific experience unnoticed, children with potential psychological symptoms may be ignored. Thus the finding that earthquake-related mental health utilization fell sharply from 34.6% in the first 15 months to 9.5% in the follow-up period raised great concerns over how to fulfill the unmet needs of psychological recovery for these children.

As the findings from the Japan and Pakistan earthquakes suggested that post-disaster chronic psychological needs were often inadequately managed and could lead to increased rates of complications and indirect morbidity after a disaster [34, 35], measures should be taken to ameliorate the persistent symptoms for child and adolescent survivors of the 2008 Sichuan earthquake. Efforts should be made in several ways. First, in order to facilitate the early identification of children with mental health problems, a comprehensive screening program should be established to evaluate the mental health conditions of these children at regular intervals. Schools may serve as an essential role in early identification and could be able to provide psychological interventions for these children. Second, as the children with mental health problems tend not to come for help, community-based mental health support—such as reaching out to them—may be a better option. In addition, all of those efforts should not be segregated from the other interventions, because these children not only have psychological needs but also require physical, economic, spiritual support as well.

Strengths and limitations

To our knowledge, this is the first community-based study that examines the longitudinal outcomes of mental health among child and adolescent survivors of an earthquake. Although community-based research has gained robust applications in indentifying and solving problems that exist in almost every corner of public health, the combination of a community-based study design and the context of a natural disaster is indeed a bold attempt. A major limitation of the study should also be recognized. All participants in the study experienced the earthquake, and they were not compared with controls from non-affected areas. It was because the Sichuan earthquake was so powerful and extensive that the shock spread over almost half of mainland China, Additionally, it is a challenge to select a significant sample size of children and adolescents who have not experienced the disaster. Even if children were selected as non-exposed, there is significant demographic and cultural variation between exposed and unexposed children. Nevertheless, as the study indicated that children with more earthquake-related experiences predicted more severe PTSD and depression, we are confident to assume that children affected by the earthquake have more severe mental health symptoms than those without the experience.

Conclusions

Problems that require treatment often do not manifest themselves until much later in life, so primary prevention is essential for young people. Identifying factors that are associated with vulnerability to post-earthquake psychological problems is the beginning for preventing public mental health nightmares in the future. Our results suggested that a substantial proportion of children who had family members or friends seriously injured, had lost family members, or had lost significant others still suffered symptoms of PTSD and depression even three years after the earthquake. We also found that the earthquake might have a delayed impact on the psychosocial functioning of children and adolescents who were not directly affected by the disaster. Despite of the crucial situation, the proportion of participants who reported earthquake-related utilization of mental health services dropped substantially from 34.6% in the first 15 months to 9.5% in the follow-up period, which raised great concerns over how to fulfill the unmet psychological needs of these children.
