研究己顯示，題自無反應的形成與安訪者及題目的特質有關，若 不加以暸解，可能會使研究結果產生偏誤。另一方面，也發現訪員特 質與受訪者在某些特殊議題的回答行為有關。因此討論題目無反應 峙，~賓將訪員、受訪者與題目，三方區的特質同時納入考慮。已有 研究者將多層線性模式(HLM) 應用於題目無反應，但這些研究只眼 於探討題目與回答者兩者，或受訪者與訪員兩者之間的E動，或者無 反應的總數與受訪者及訪員之間的關係。本研究以HLM 中的三層模 式來探討題目特質、受訪者與訪員三者對於無反應的影響。所使用的 方法是先依攘題目的特質(面向)分類後，再以三層模式分析這些面 向中的無反應，同時暸解訪員特質、受訪者特質、與題目面向三者的 影響。我以分析台灣地區社會變遷基本調查第三期四次的傳播組中的 十個題目做為例子，並討論其結果。

Item nonresponse has been shown related to respondent and item characteristics. On the other hand, interviewer characteristics also have been found related to response behavior on some special issues. Therefore, in studying item nonresponse, we need to take into consideration characteristics of al1 three above, namely, the interviewer, the respondent and the items. To solve the problem, this study groups items based on what they measure or what mechanism they might activate (dimension), and then uses the 3-1evellogistic model to analyze them, so that the threeway interaction among the items' dimensions, the respondent and the interviewer can be investigated. N onresponse from 10 questions in the Mass Media Volume (volume 1) of the Taiwan Social Change fourth survey of the third period are analyzed as an example. Results and implications are discussed.
