Introduction: Today, the health information and services are delivered via internet and other communication devices, accessing which requires some capabilities and skills known as eHealth literacy. The aim of this study was to determine the state of the eHealth literacy of postgraduate students in Tehran University of Medical Sciences, Tehran, Iran, in 2015-2016 educational years.Methods: This was a descriptive survey carried out among 700 postgraduate students of six selected majors in Tehran University of Medical Sciences. The sample size was determined to be 248, using Morgan table. Sampling was carried out using proportional sampling method. The data were collected through a questionnaire. The validity of questionnaire was confirmed through the experts’ opinions, and its reliability was measured through Cronbach’s alpha (α = 0.752). The collected data were analyzed using one-sample independent t test.Results: The mean score of eHealth literacy among the sample of study was 48.367, which was above the average (t = 17.692, P < 0.001). There was no significant difference between eHealth literacy level among men and women. The eHealth literacy level of PhD students was estimated to be higher than MSc Students.Conclusion: The studied population needs to be strengthening in the fields of working with word processors and understanding, evaluating, and interpreting research data. Being higher than average in eHealth literacy shows that studied population may be used as eHealth literacy instructors for other parts of society.

Introduction: Considering the importance of using indexing tools such as thesauri and Medical Subject Headings (MeSH) in storage and retrieval of medical information, this study was performed with the aim to determine the compliance rate of keywords of articles published in an English-language journal Shahid Beheshti University of Medical Sciences, Journal of Paramedical Sciences, with the MeSH.Methods: This was a cross-sectional and descriptive study using applied method. The data gathering tool was a researcher-made checklist. In total, 1143 keywords extracted from 269 articles published in 24 issues of the journal; those keywords were compared with MeSH, and were classified in three groups: exact match, partial match and no match.Results: During the investigated years, on average, 277 keywords (24.2%) were exact matches, 409 keywords (35.8%) were partial matches, and the 457 keywords (40.0%) were not match with the terms contained in the MeSH. Keywords in match or match with the entry term categories formed the largest portion of partial match keywords.Conclusion: The results show that the authors of this journal do not have sufficient knowledge on correct keyword selection with use of the MeSH, and it is necessary for them to be trained in the correct way. In addition, the editorial board of this English-language Iranian journal in the paramedical field should request authors to adjust their keywords based on the MeSH during article selection.

Introduction: Search tools including Search Engines, Meta Search Engines and Subject Directory are used to find the needed information in the World Wide Web. The aim of this study was to compare selected Search Engines and Meta Search Engines in retrieving information concerning physiotherapy from the World Wide Web to determine overlap among them.Methods: The current study was carried out using descriptive comparative methods. Seven search engines and seven meta search engines introduced by ";searchinginewatch.com"; as the most frequently used ones, were analyzed. Then subject sub category of physiotherapy in eight subject fields were chosen from Medical Subject Headings (MeSH) as keywords. After choosing keywords, a search was made via using the search and Meta search engines to identify how many results could be obtained by studied search engines for each individual keyword. Finally the rate of overlap among search engines and meta search engines was measure in terms of percentage. The obtained data were then analyzed using descriptive methods and the SPSS.Results: According to the result of this study, ";Altavista";, All the web ";and";Google"; showed the higher most retrieved results. Among the Meta search engines ";Ixquick"; got the first rank. Search results of ";Altavista"; and ";all the web";,"; Vivsimon"; and ";Clusty"; and ";Metacrawler"; and ";Dogpile"; showed large overlaps. Moreover, overlap percentage between search engines and Meta search engines with respect to keyword, was determined in this study.Conclusion: In this study, the percentage of overlap among selected search engines and meta search engines using the selected keywords, was shown to be 40% - 60% . This difference was because of variety of results ranking methods in different search engines and Meta search engines.Keywords: Medical Information Storage and Retrieval; Physical Therapy (Specialty); Internat
