The purpose of this paper is to assess the quality of Iranian university libraries.,This first systematic review and meta-analysis were based on the PRISMA guidelines by searching in national and international databases from 2003 to January 2017 with standard Persian and English keywords. Data searching, extracting and quality appraising were completed by two researchers, independently. Any unexpected documents were assessed by a third expert researcher. Data were extracted in accordance with the “Strength of the Reporting of Observational Studies in Epidemiology” checklist after the final selection of appraised documents. Random effects size based on Cochrane test and I2 were used for combining the obtained results from different studies together by considering the heterogeneity of studies.,Based on the meta-analysis conducted in 25 (6.42 percent) included studies, the total sample size was estimated. According to three dimensions of LibQUAL, findings of current information control, affect of service and the library as a place were estimated as 5.37 [CI95%: 5.02, 5.73], 6.91 [CI95%: 5.56, 6.26], and 5.46 percent [CI95%: 5.2, 5.73], respectively. Also, mean of service adequacy and superiority gap are equal to 0.07 [CI95%: −0.22, 0.36] and −2.06 [CI95%: −2.89, −1.23], respectively. There was a significant correlation between three dimensions of service quality and service superiority gap of LibQUAL and geographical regions of Iran (p<0.01). Also, a significant correlation was found between the gaps of services and three aspects of LibQUAL model and published years through a meta-regression test (p<0.01).,The results obtained from the present study showed that users are relatively satisfied with the quality of services provided by Iranian university libraries. An improvement in the quality of library services can promote the scientific level of universities.,The results of the present systematic review and meta-analysis study demonstrate a vital connection between primary research studies and decision-making for policymakers in Iranian university libraries to increase quality services.

基于LibQUAL模型的伊朗高校图书馆服务质量的元分析。

本文的目的是评估伊朗大学图书馆的质量。这项首次系统的综述和荟萃分析是根据PRISMA指南，通过搜索2003年至2017年1月在全国和国际范围内使用标准波斯语和英语关键字的数据库进行的。数据搜索，提取和质量评估由两名研究人员独立完成。任何意外的文件均由第三位专家研究员评估。在最终选择评估文件后，根据“流行病学观察性研究报告的强度”清单提取数据。考虑到研究的异质性，使用基于Cochrane检验和I2的随机效应量将不同研究的结果合并在一起。基于25的荟萃分析（6。42％）纳入研究，估计总样本量。根据LibQUAL的三个维度，当前信息控制，服务影响和图书馆作为场所的发现估计为5.37 [CI95％：5.02，5.73]，6.91 [CI95％：5.56、6.26]和5.46％[CI95 ％：5.2、5.73]。此外，服务充足性和优势差距的平均值分别等于0.07 [CI95％：-0.22、0.36]和-2.06 [CI95％：-2.89，-1.23]。LibQUAL的服务质量和服务优势差距的三个维度与伊朗的地理区域之间存在显着相关性（p <0.01）。此外，通过元回归检验，在服务差距和LibQUAL模型的三个方面以及已发表的年份之间发现了显着的相关性（p <0.01），从本研究中获得的结果表明，用户对伊朗大学图书馆提供的服务质量相对满意。图书馆服务质量的提高可以提高大学的科学水平。本系统综述和荟萃分析研究的结果表明，伊朗大学图书馆的决策者应在基础研究和决策制定之间建立至关重要的联系，以提高质量服务。
