On the Risks of Medicalization of Adolescents Self-Injuring Acts

引用

Open Journal of Psychiatry 2021年第1期11卷 29-46页

作者： Inger ekman Lars Jacobsson Department of Social Work Ume&#229 University Ume&#229 Sweden Department of Clinical Sciences Psychiatry Ume&#229 University Ume&#229 Sweden

Although common among community adolescents, self-injuring acts are mainly studied by psychiatrists and psychologists and rarely by social work researchers. The preponderance of medical research in the field has come to associate self-injuring acts with mental issues. This view has to a large extent been adopted among professionals as well as among laypeople. When examining adolescents’ unsolicited internet published narratives, this medicalization of self-injuring acts was found to have negative consequences for disclosure and help-seeking, and hence limit the adolescents’ possibilities to get adequate help and support. The main objective of this work is to study adolescents’ views on hampering factors for help-seeking for self-injuring acts and the role of medicalisation for their willingness for disclosure and help-seeking. Disclosure of self-injuring acts within the social network was described as met with demands to seek professional mental help. Seeking professional help was accompanied with fear of being perceived as crazy or diagnosed as mentally ill. Internet websites were described as value free and safe arenas giving opportunity to disclose self-injuring acts without fear of being stigmatized and labelled as mentally ill. An extended involvement of social work researchers and professionals, approaching self-injuring acts not primarily as a sign of mental problems, but as an adolescent way of trying to manage a complicated social context, could enhance finding adequate support systems. It is also necessary that the medical profession contributes to a demedicalization of self-injuring acts.

中国作为一个拥有世界20%人口的国家,却只拥有世界可耕用地的7%。据一些西方媒体报导,在2008年中国食品危机发生之后,中国为了保证其食品供应免受国际市场不稳定因素所造成的负面冲击,开始采取纵向一体化的战略,向海外租用农业用地;进一步,有些西方媒体又将中国的这种行为贴上了新殖民主义的标签。为了研究中国在莫桑比克从事的农业活动,本人在莫桑比克进行了实地调查,获得了大量的第一手或第二手材料。本文以这些材料为基础,探讨了中国在海外租用农业用地战略的可行性。研究表明,即便向海外寻求土地资源可以起到适当分散粮食安全风险的作用,但它并不是中国本土粮食生产和供应的完美替代。一个更加有趣的发现是,目前莫桑比克并不存在旨在将农业产品出口到中国的中国投资项目。这个研究结果与许多大型非政府组织和国际机构目前所相信的媒体说法正好相反。本文研究并不支持中国在非洲奉行“新殖民主义”的论点。站在非洲国家的角度看,中国的角色并不是所谓的“殖民者”,而是他们的战略合作伙伴。与发达国家相比,中国对非洲实施援助的一大特点是将援助与商业运营和技术转移密切结合在一起,能够更加有力地促进非洲本身的发展;当然,在此过程中,中国也会获得很大的好处。简言之,对中非而言,这是一个双赢博弈。关于中国在非洲租用土地的动机,西方媒体认为主要是因为中国的农业耕地非常有限,进而需要拓展“生存空间”。但需要注意的是,尽管其农业耕地非常有限,现在中国95%的食品需求仍是由国内生产而供应的。本文分析表明,中国企业之所以海外租用农业用地的动力,主要还不是因为中国国内土地资源的稀缺,而是因为中国拥有适合于非洲当地情况的农业技术。正因如此,通过援助和开发非洲,中国企业(包括国有的和私营的)不但有利于非洲本身的繁荣,也能够在此过程中获得自身发展的机会。
