摘要

A. M. Rubin等學者所擬之「擬社會互動量表」為傳播學界中廣泛使用之量表。先前研究，不管是概念上或於測量上，均以單一構面來探討「擬社會互動量表」。本論文分為三個研究主題，主要探討「擬社會互動量表」的因素構面。研究一比較「擬社會互動量表」之單因子模型、雙因子模型、以及三因子模型的適切度。研究二使用不同的樣本複製研究一之結果。研究三檢驗模型在三個不同時間點中的適切度。研究結果指出三因子模型具最佳的適切度。此一結果可以幫助學界更了解「擬社會互動」之本質與測量方法。

Although originally posited as a unidimensional measure, it has recently been suggested that A.M. Rubin et al.'s PSI Scale may be multidimensional. This paper investigates the dimensionality of the PSI scale in three studies. Study 1 examined the dimensionality of the PSI scale by asking participants rate the scale items regarding their ”favorite TV character.” The fit of 1, 2, and 3 factor models were compared. In order to replicate the findings of study 1, study 2 followed the same procedure using a very different sample. Study 3 expanded the findings of the previous studies and examined the fit of the 3-factor model across three time points and with specific content. Results of all three studies suggest that a three-factor model provides the best fitting solution in all cases. We discussed our findings in terms of conceptual and methodological issues in the measurement of PSI.
