Prevalence of major depressive disorder in the general population of South Korea

Sex Differences in Genetic and Environmental Contributions to Depression Symptoms in South Korean Adolescent and Young Adult Twins

“…The mean score of the CES-D in the present sample was higher than that reported by Kim et al (2000) who studied the CES-D in a nationwide singleton sample aged between 15 and 19 years (16.4 vs. 12.8). However, given that the CES-D data were collected in 1995 in the Kim et al study, while the present data were collected in 2006, the mean difference between the Kim et al and the present study is likely to reflect a secular increase in reporting symptoms of depression in South Korean population (Ohayon & Hong, 2006).…”

Concordance between telephone survey classification and face-to-face structured clinical interview in the diagnosis of generalized anxiety disorder in Hong Kong

“…For example, although most face-to-face surveys using structured diagnostic schedules in Chinese communities showed very low rates of mental disorders (Chen et al, 1993;Shen et al, 2006), several telephone surveys of anxiety and depressive disorders in Hong Kong have revealed prevalence estimates comparable to those found in Western societies (Lee, Tsang, & Kwok, 2005, 2007a. Likewise, with a high participation rate of 91.4%, a telephone survey of the general population in South Korea revealed that major depressive disorder was significantly more common than what was found in previous Korean surveys based on the face-to-face mode of interviewing (Ohayon & Hong, 2006). Authors of these Asian surveys speculated that the anonymity of telephone interviewing could reduce stigma, thereby facilitating symptom expression and more accurate prevalence estimates to be found.…”

“…Widely cited community psychiatric surveys are still based on face-to-face structured interviews and have been mostly carried out in Western societies that can afford this mode of research. Notwithstanding certain inherent limitations, telephone surveys of mental disorders confer several advantages such as affordability, quick turnaround time, wide geographic coverage, anonymity and, arguably, facilitation of disclosure about stigma-sensitive information (Evans, Kessler, Lewis, Peters, & Sharp, 2004;Fenig, Levav, & Kohn, 1993;Ohayon & Hong, 2006;Rohde, Lewinsohn, & Seeley, 1997). Therefore, it is worthwhile to explore their utility in scenarios where face-to-face interviews are not feasible, such as middle and low income countries with scarce resources for mental health research (Sharan, Levav, Olifson, de Francisco, & Saxena, 2007).…”

Risk Factors for Drug Abuse Among Nepalese Samples Selected from a Town of Eastern Nepal

“…A total of 95,332 people reside in 103.38 km 2 areas of Dharan (CBS 2003). With the reference of 20.9% depression in general population (Ohayon and Hong 2006) and 51.5% of depression among drug abusers (Agrawal et al 2006), the sample size was determined as 150 pairs of cases and controls for this study design. This provides 80% power to detect an odds ratio of 2.0 or higher at 5% level of significance, which also includes 10% increment in the sample to overcome non-responses in the community.…”
