This study is a national-level economic cost-estimates of injury from interpersonal and self-directed
violence for Thailand during 2005 using the World Health Organization-US Centers for Disease Control and
Prevention’s guidelines. Direct medical costs from self-directed violence totaled 569 million Baht (THB) while
the cost of interpersonal violence was THB 1.3 billion. Productivity losses for injuries due to self-directed
violence were estimated at THB 12.2 billion and those for interpersonal violence were THB 14.4 billion. The
total direct medical cost, thus, accounted for about 4% of Thailand’s total health budget while the productivity
losses accounted for approximately 0.4% of Thailand’s GDP. In summary, interpersonal and self-directed
violence caused a total loss of 33.8 billion baht for Thailand in 2005. More than 90% of the economic loss was
incurred from productivity loss and about four-fifths came from men.
