摘要

The evaluation of reference service requires a multi-level research design that can account for the effects of intra-class correlation that arise as the result of gathering multiple observations from each library and librarian participating in the study. Few studies have ever tested for these effects that tend to diminish the value of the standard error, misleading the investigator into believing that a relationship between variables has been discovered which does not necessarily exist. Although many previous studies have focused on a single outcome variable, this study attempted to measure the influence of seventeen predictors on three outcomes: the accuracy of the information received by the library user, the utility of the information received by the user, and the inquirer's satisfaction with the reference process. Evidence suggested that little variance in the outcome variables was explained as differences between librarians or between libraries. The potential danger of intra-class correlation was low. Variables that predicted a significant effect on the outcome measures include the extent to which the librarian followed the RUSA Behavioral Guidelines, the difficulty of the query, the user's level of education, the user's familiarity with using the library, and the level of service provided by the library. Variables that did not predict any significant effect on the outcome measures include the librarian's experience and education as well as the size of the library collection.

機譯：參考服務的評估需要一個多層次的研究設計，該設計可以解釋類內(nèi)相關性的影響，這些影響是由于從參與研究的每個圖書館和館員那里收集了多個觀察結果而產(chǎn)生的。很少有研究對這些影響會減小標準誤差值的影響進行過測試，從而使研究人員誤以為已發(fā)現(xiàn)不一定存在的變量之間的關系。盡管以前的許多研究都集中在單個結果變量上，但本研究試圖衡量17個預測變量對三個結果的影響：圖書館用戶接收到的信息的準確性，用戶接收到的信息的實用性以及查詢者的對參考過程滿意。有證據(jù)表明，結果變量的差異很小，可以解釋為圖書館員之間或圖書館之間的差異。類內(nèi)相關的潛在危險很小。可以預測對結果度量有重大影響的變量包括：圖書館員遵循RUSA行為準則的程度，查詢的難度，用戶的受教育程度，用戶對使用圖書館的熟悉程度以及圖書館提供的服務水平圖書館。不能預測對結果衡量有任何重大影響的變量包括圖書館員的經(jīng)驗和教育程度以及圖書館藏書的規(guī)模。
