同調動機尺度の開発のための予備的検討 : 規範的影響と情報的影響を超えて

Recently, motivations for conformity, classified as normative and informational influences, have been questioned (cf. Kane et al., 2021; Smith & Haslam, 2017). If there are other essential motivations for conformity, the current classification method lacks content validity (Murayama, 2012). Therefore, this study aims to explore further motivations for conformity and statistically examine the validity of the new classification. For this purpose, a preliminary survey was conducted to develop a new scale, the Motivation of Conformity Scale, which classifies and measures conformity based on its motivations. First, an open-ended questionnaire was administered to identify existing motivations for conformity. Next, the sentences collected from the questionnaire were classified based on the KJ method (Kawakita & Makishima, 1970). As a result, the existence of five motives was suggested. Then, we created scale items based on the analysis results and the sentences. Next, to examine the scale validity, a questionnaire was administered to 273 university students, and an analysis was conducted. We examined scale validity based on Murayama's (2012) and Nakamine & Kamijo's (2019) arguments. The scale displays a degree of content validity, although further research and evaluation are warranted.
