| Summary: | 碩士 === 慈濟大學 === 公共衛生學系碩士班 === 100 === Objective: This study aimed to: 1. investigate the prevalence rates and pattern of traumatic events experienced by the Indigenous and Han adolescents, 2. investigate if they develop trau-matic stress responses and substance misuse, 3. explore the relationship between social support and post-traumatic stress responses.
Method: The participants were students of the 7th and 8th grads in Hualien country. The total of participants was 621 students. Structured questionnaires were used to assess the experience of traumatic events, stress response, and the degree of social support. The questionnaires were self-administered, including: post-traumatic stress scale -Youth Edition and the Taiwan Relationship Inventory for Children and Adolescents. Data collection was carried out in class.
Results: 371 participants accounting for 59.7% experienced at least a traumatic event. There was no significant difference in pervelance rates of traumatic events between males and females, but females hada significantly higher rate of witnessed sexual violence compared to males. In addition, participants of Taroko and Amis origin had significantly higher rates of traumatic events than the Han counterparts. 19 participants met the PTSD diagnosis, the prevalence rate was 3.1%. There were more females (4%) met the PTSD diagnosis than males (1.9%), but the difference was not significant. Moreover, there was no difference be tween 3 ethnic groups. The factors signifycnatly associated with PTSD severity were the number of traumatic events, negative interaction with primary carers, and negative interaction with peers. .The negative interaction with primary carers mediated the relation between traumatic events and PTSD severity. However, when examinating separately, the results showed different patterns of factors assoaciated with PTSD severity in these ethnic groups.
Conclusion: There was no significant gender difference in the prevelance rate of traumatic events, but there were no significant ethnic differenct rates. The negative interaction with primary carers mediated the effect of the number of traumatic events on PTSD severity, which supported the notion of the mediating effect of social support.
The results suggest that attention should be focused on the specific types of traumatic event, and that the planning of PTSD prevention programes should be aimed at strengthening the social support of youths. It is hoped that by reducing the occurrence of traumatic events would lead to less stress responses displayes by the youths, which in turn improve their mental health status.
