**5. Psychiatric studies of post-Chi-Chi earthquake survivors**

Researchers focusing on survivors of the Chi-Chi earthquake in Taiwan (Su, Chou, Lin, Tsai, 2010) have found evidence of psychological sequelae that includes posttraumatic stress disorder (PTSD), major depressive disorder, sleep disorder, anxiety, and substance abuse (Chou et al., 2004a, 2004b, 2005, 2007; Chen et al., 2001; Chang et al., 2002; Lai et al., 2004; Hsu et al., 2002; Kuo et al., 2003; Liu et al., 2006; Tsai et al., 2007; Wu et al., 2006; Yang et al., 2003). The quality of life for survivors of traumatic events who develop psychiatric illnesses or impairments is worse than that for survivors without any psychiatric illness (Chou et al., 2004b; Tsai et al., 2007; Wu et al., 2006). In addition, rescue workers such as nurses, fire fighters, and soldiers may develop physical or mental impairments (Chang et al., 2008; Liao et al., 2002; Shih et al., 2002; Yeh et al., 2002). We used PubMed to identify Chi-Chi earthquake-related papers published through June of 2009. All of the Chi-Chi earthquake papers related to psychiatry are summarized in Table 1 (cited from Su, Chou, Lin, Tsai, 2011).
