Self-reported Internalizing and Externalizing Behaviours among Junior High School Students at 2 and 4 Years after the 921 Earthquake in Taiwan

Abstract

We examined the impact of the 921 Taiwan Earthquake on internalizing and externalizing behaviours among junior high school students 2 and 4 years after the earthquake. This study was a secondary analysis using data extracted from the Taiwan Education Panel Survey and included 12111 students. The impact of the earthquake was assessed by the length of time to restore the home environment and whether a family member died or was severely injured in the earthquake. Generalized estimating equations showed that living in an urban area and a longer duration after the earthquake were associated with increased internalizing and externalizing behaviours. Boys reported more externalizing but fewer internalizing behaviours than girls. After adjustment for those variables, having a family member who had died or was severely injured was not significantly associated with increased internalizing and externalizing behaviours. However, a longer duration of time to restore the home environment was significantly associated with these behaviours. Regardless of the impact level of the disaster, adolescents had increased internalizing and externalizing behaviours from the seventh to ninth grades. Post-disaster mental health services should continue monitoring and supporting children whose ordinary home living is affected by a natural disaster up to 4 years post-disaster.

Statistical analysis of childhood and early adolescent externalizing behaviors in a middle low income country

“…Children's exposure to heavy metal contamination [14] and noise pollution [15] exhibit high levels of deviant and disruptive behaviors. Natural disasters like earthquakes [16] and hurricanes [17] can trigger externalizing tendencies in children and young adults.…”

Addressing Disaster Exposure Measurement Issues With Latent Class Analysis

“…Instead of creating a continuous sum score, critical experiences from the disaster, such as death of a loved one or time displaced from one's home, are used to examine differences between groups of exposed individuals. For example, Liao, Chen, Chen, and Chien () used this approach, identifying death or injury of a family member and time until the home was restored following a massive earthquake in Taiwan. These authors compared MH outcomes for children who experienced each of these items and those who did not.…”

Survey dataset on the types, prevalence and causes of deviant behavior among secondary school adolescents in some selected schools in Benin City, Edo State, Nigeria

“…Evolving trends and behavioral patterns are often observed and made available as scientific findings. Some examples can be seen in [16] , [17] , [18] , [19] , [20] , [21] , [22] , [23] , [24] , [25] , [26] . Different statistical analysis can be useful for further behavioral analysis [27] , [28] , [29] , [30] , [31] , [32] .…”
