Purpose

The purpose of this study is twofold. First, the study shall evaluate the extent of usage of grey literature and its different types of addiction research. The second purpose of the research is to analyze the extent of usage of reports such as research reports, survey reports, data reports, etc. As the reports are produced in general by various organizations and can be accessed by not only academicians but also the general public, they play an important role in the dissemination of research to the people. Therefore, the study endeavored to identify the major organizations that are involved in the publishing of research reports in the field of addiction.

Design/methodology/approach

Scopus database was used for the purpose of collecting the data. References in the reference lists of the articles published in 2018 in the journal Psychology of Addictive Behaviors of the American Psychological Association were collected. Scopus indexes the references of the papers in two different categories, namely, indexed in scopus/scopus references and reference lists. They were then categorized as grey literature and non-grey literature. Further, reports were searched manually so that their producers/authors can be found and categorized according to the organizations.

Findings

The study found that grey literature comprises a very small proportion of citations in addiction research (just approximately 5 per cent). This suggests that the improper indexing and bibliographic control of grey literature may be one of the reasons behind the low numbers. Reports comprised the largest proportion of the grey literature cited in addiction research, followed by software documentation, unpublished manuscripts, guidebooks, handbooks, manuals, websites, government publications, etc. The reports of the US Department of Health and Human Services comprised the maximum citations in the reports category because of the reports produced by organizations like Substance Abuse and Mental Health Services Administration (SAMHSA) which comprised 17.59 per cent of the total reports. National Institute of Health (USA) and Centers for Disease Control and Prevention and others. Other than the reports of the organizations of the USA, the reports published by the organizations of Canada, Australia, UK, New Zealand and one European Body were also cited by the articles of the journal.

Practical implications

The research focuses on the use of grey literature in addiction research. The findings of the study indicate very low citations to grey literature in addiction research. This reinforces the need for a separate worldwide information retrieval system for grey literature for researchers to conduct systematic reviews.

Originality/value

Very few studies have been conducted on the use of grey literature and hardly any research focuses on the use of grey literature in addiction research. The study goes one step further and identifies major organizations that are involved in the production of research reports in the field so that their reports can be properly indexed.

灰色文献在成瘾研究中的使用和多样性分析：一项研究

目的

这项研究的目的是双重的。首先，研究应评估灰色文献的使用范围及其不同类型的成瘾研究。研究的第二个目的是分析报告的使用范围，例如研究报告，调查报告，数据报告等。由于这些报告通常是由各种组织制作的，不仅可以由院士访问，而且可以由一般学者访问。在公众中，它们在向人们传播研究成果方面发挥着重要作用。因此，本研究致力于确定参与成瘾领域研究报告出版的主要组织。

设计/方法/方法

Scopus数据库用于收集数据。收集了2018年在《美国心理学会心理学上瘾行为心理学》上发表的文章的参考文献清单中的参考文献。Scopus将论文的参考文献分为两个不同的类别，即在scopus / scopus参考文献和参考文献列表中进行索引。然后将它们分为灰色文献和非灰色文献。此外，手动搜索报告，以便可以根据组织查找其作者/作者并对其进行分类。

发现

该研究发现，灰色文献在成瘾研究中仅占很小的比例（仅约5％）。这表明灰色文献的索引编制和书目控制不当可能是数量偏低的原因之一。在成瘾研究中引用的灰色文献中，报告所占比例最大，其次是软件文档，未出版的手稿，指南，手册，手册，网站，政府出版物等。美国卫生与公共服务部的报告中所引用的文献最多。之所以在报告类别中，是因为药物滥用和精神卫生服务管理局（SAMHSA）等组织制作的报告占报告总数的17.59％。美国国立卫生研究院，疾病控制与预防中心等。除美国组织的报告外，该杂志的文章还引用了加拿大，澳大利亚，英国，新西兰和一个欧洲机构组织发布的报告。

实际影响

该研究的重点是在成瘾研究中使用灰色文献。该研究的结果表明，成瘾研究中对灰色文献的引用很少。这就增强了对灰色文献使用单独的全球信息检索系统的需求，以供研究人员进行系统的审查。

创意/价值

关于使用灰色文献的研究很少，并且几乎没有任何研究将灰色文献用于成瘾研究。这项研究又向前迈进了一步，确定了参与该领域研究报告编制的主要组织，以便可以对其索引进行适当索引。
