道具的–自己充足的コミュニケーション尺度の作成——高次因子構造からの妥当性・信頼性の検討——

This study aims at developing instrumental-consummatory communication scales and testing their validity and reliability by examining higher-order factor structures. Twenty-six items were composed in accordance with the definition offered by Festinger (1950) and related discussions. Through maximum likelihood exploratory factor analyses with promax rotation, after deleting five items that did not satisfy our content validity criteria, 21 items converged into 16 item with four factors, i.e., efficiency-clarity (4 items, α=.82), harmonic influence (3 items, α=.82), thoughts organizing (5 items, α=.88), and catharsis (4 items, α=.84) factors. The first two are considered to be sub-factors of instrumental communication and the latter two are thought to be sub-factors of consummatory communication. A series of confirmatory factor analyses and likelihood ratio tests across nest models showed that the fit of the higher-order solution did not significantly deviate from the first-order solution. Based on the fact that one less freely estimated parameter of the second-order model appropriately accounted for the six correlations among factors of the first-order model, it is concluded that the second-order factor model is more appropriate than the first-order model. In addition to the factorial validity of these scales, convergent and discriminant validity tested with related psychological scales and criterion-related validity hypothesized with gender differences in instrumental/consummatory communication were mostly confirmed.
