This study examined the impact of the 2004 Asian tsunami on 400 Thai adolescents 1 year after the disaster. Quantitative analyses showed that youth behavior problems were positively associated with tsunami experiences and negatively associated with positive family functioning. Tsunami exposure, school connectedness, religious beliefs and practices, and availability of mental health services did not predict behavior problems. Sequential regression analysis was performed with age, gender, tsunami experiences, and family functioning predicting youth behavior problems. In-depth interviews with 40 adolescents revealed many losses and difficulties after the tsunami, including death of parents and school difficulties. Positive aspects of recovery were support from family, peers, and other social networks and increased educational opportunities. (Contains 4 tables.)
