OBJECTIVES
This study updated Reed's 1999 "Mapping the Literature of Occupational Therapy." An analysis of citation patterns and indexing coverage was undertaken to identify the core literature of occupational therapy and to determine access to that literature.
METHODS
Citations from three source journals for the years 2006 through 2008 were studied following the common methodology of the "Mapping the Literature of Allied Health Project." Bradford's Law of Scattering was applied to analyze the productivity of cited journals. A comparative analysis of indexing was conducted across three bibliographic databases.
RESULTS
A total of 364 articles cited 10,425 references. Journals were the most frequently cited format, accounting for 65.3% of the references, an increase of 4.1% over the 1999 study. Approximately one-third of the journal references cited a cluster of 9 journals, with the American Journal of Occupational Therapy dominating the field. An additional 120 journals were identified as moderately important based on times cited. CINAHL provided the most comprehensive indexing of core journals, while MEDLINE provided the best overall coverage.
CONCLUSIONS
Occupational therapy is a multidisciplinary field with a strong core identity and an increasingly diverse literature. Indexing has improved overall since 1999, but gaps in the coverage are still evident.
目的
本研究更新了里德（Reed）1999 年的“职业治疗文献图谱”。对引文模式和索引覆盖范围进行了分析，以确定职业治疗的核心文献，并确定获取该文献的途径。
方法
采用“辅助卫生领域文献图谱项目”的通用方法，研究了 2006 年至 2008 年三个来源期刊的引文。布拉德福（Bradford）的分散定律被用于分析被引期刊的生产力。对三个书目数据库进行了索引比较分析。
结果
共有 364 篇文章引用了 10425 条参考文献。期刊是最常被引用的格式，占参考文献的 65.3%，比 1999 年的研究增加了 4.1%。大约三分之一的期刊参考文献引用了 9 种期刊组成的集群，其中《美国职业治疗杂志》（American Journal of Occupational Therapy）占据主导地位。根据被引次数，另外 120 种期刊被确定为中等重要性。CINAHL 对核心期刊的索引最全面，而 MEDLINE 提供了最佳的整体覆盖范围。
结论
职业治疗是一个多学科领域，具有强烈的核心身份和日益多样化的文献。自 1999 年以来，索引总体上有所改善，但覆盖范围仍存在差距。
