Abstract
The reasoning behind this study was to determine the most frequently cited journal publications in five physiotherapy journals during a one-year period, and which of five medical indexes provides the most comprehensive review of journals cited. The list of journals most frequently cited in the five journals of interest was created by determining the citation frequency of all cited journals in each of the ‘core’ citing journals. The top 10% of journals (in terms of citation frequency) from each of the five citing journals were combined to produce a master list of the most frequently cited journals. This master list was cross-tabulated with five different medical indexes (Cumulative Index of Nursing and Allied Health, Excerpta Medica, Index Medicus, Physiotherapy Index, Science Citation Index) to determine the comprehensiveness of the database of each index with regard to physiotherapy literature. The Cumulative Index of Nursing and Allied Health was not as thorough as the other indexes in its inclusion of cited journals. No single index database provided adequate coverage of the journals most frequently cited in the five physiotherapy journals. The most comprehensive coverage was provided by pairs of indexes that have strengths in different areas.
