Background:
The relationships between acculturation and suicide were investigated in East Taiwan.
Methods:
Psychological autopsy interviews were conducted for consecutive suicides from two native Taiwanese groups (Atayal and Ami) (N = 30 for each group); each of them was matched with two controls for age, sex and area of residence. The Taiwan Aboriginal Acculturation Scale was used to measure the extent of acculturation.
Results:
A lower degree of social assimilation was significantly associated with a higher risk of suicide in the Atayal and the male groups. In multivariable regression analysis, a significant effect of low social assimilation on the risk of suicide was found in Atayal and in men, even after controlling for the effects of ICD-10 depressive episode and emotionally unstable personality disorder. Meanwhile, there was a significant trend across low, moderate and high social assimilation on suicide risk in Atayal and in men.
Conclusions:
For the native Taiwanese, the stress from rapid acculturation into the main Chinese society is crucial to their mental health. It might be reduced through targeted social and educational programmes.
