日本版Sociocultural Attitudes Towards Appearance Questionnaire-3短縮版(SATAQ-3 JS)の開発と信頼性・妥当性の検討 Development of the Sociocultural Attitudes Towards Appearance Questionnaire-3 Japanese Short Version (SATAQ-3 JS) and Establishment of its Reliability and Validity
本研究は,摂食障害の要因となるボディイメージの歪みの原因とされる,メディアのメッセージをどれだけ内面化し影響を受けているかを評価するSociocultural Attitudes Towards Appearance Questionnaire-3(SATAQ-3)の12項目の日本語短縮版(SATAQ-3 JS)を作成し,その信頼性・妥当性を,女子学生を対象に検討した.結果から,SATAQ-3 JSは,オリジナル尺度と同様に4因子からなり,また,合計得点と各下位尺度は内的一貫性があり,身体不満足感,やせ願望,ダイエット傾向,社会的比較と高い相関関係にあることから,信頼性と妥当性のある,スクリーニングに適した尺度であることが示された.また,SATAQ-3によって評価することができるボディイメージにかかわる心理社会的諸要因が,日本人女性の食行動の問題においても重要であることが示唆された.
Background: The increase in eating disorder cases in Japan is an important social issue. Body dissatisfaction has been studied as one of the major risk factors of eating disorders, and body image is strongly influenced by the media exposure. Therefore, prevention of media exposure effects may be a key to intervene eating problems. Objectives: This study was conducted to develop the Japanese short-version of the Sociocultural Attitudes Towards Appearance Questionnaire-3, which assesses to what extent individuals internalize media messages and are influenced by them, as well as to establish its reliability and validity. Subjects/Method: In total, 283 female college students whose average age was 19.9 (SD=2.38) and BMI was 20.90kg/m^2 (SD=2.84) were given the SATAQ-3 Japanese version, along with the scales to assess body dissatisfaction, dieting behaviors, drive for thinness, and body comparison. Results: Exploratory factor analysis indicated that SATAQ-3 JS that consisted of 12 items had a four-factor structure. Internal reliabilities of its total and four subscales were all high. Also, it had positive correlations with body dissatisfaction, drive for thinness, dieting behaviors, and body comparison measures. Conclusion: SATAQ-3 JS has a high reliability and validity, which is expected to be useful to screen young females who are likely to be adversely influenced by media exposure. Its clinical and practical usefulness is highly plausible. Moreover, this study indicates that the factors related to body image disturbance are significantly intertwined among Japanese females.
