Since the beginning of the human race, individuals have migrated alone or in groups. This process of migration has often been considered to be an aetiological factor in the genesis of many mental disorders.
Two studies collecting rates of first onset schizophrenia in Trinidad and in London using the same assessment instruments.
The sending countries have low rates of schizophrenia. The impact of migration itself produces high stress but rates of schizophrenia are even higher in the second generation, suggesting that that other social factors may be responsible for the increase if genetic vulnerability is excluded.
Individual social factors, such as cultural identity and the impact of racism, are more likely to play a key role in the genesis of schizophrenia.
自人类诞生以来，个体就一直独自或成群地迁徙。这种迁徙过程常被认为是许多精神障碍发病的一个病因因素。
两项研究使用相同的评估工具收集了特立尼达和伦敦首次发病精神分裂症的发病率。
移民输出国精神分裂症发病率较低。移民本身会产生高压力，但第二代的精神分裂症发病率更高，这表明如果排除遗传易感性，其他社会因素可能是发病率增加的原因。
个体社会因素，如文化认同和种族主义的影响，更有可能在精神分裂症的发病中起关键作用。
