Rape myth acceptance (RMA) is the acceptance of false beliefs, stereotypes, and statements about rape victims, perpetrators, and the act itself. RMA positively predicts shame felt by victims and negatively predicts reports of sexual victimization. Knowledge about sexual violence changes over time; accordingly, psychometric scales measuring RMA should be updated. Hahnel-Peeters and Goetz developed the Rape Excusing Attitudes and Language (REAL) scale by updating the Illinois RMA Scale—a major instrument used in the United States. However, the REAL scale is not available in Japanese. Therefore, we developed and validated a Japanese version of the REAL scale, evaluated RMA in Japanese individuals ( N = 1,000), and compared the Japanese participants’ RMA levels with the mean participant scores from Hahnel-Peeters and Goetz. In collaboration with one of the original authors, the Japanese version was developed through a back-translation process and administered to 1,000 men and women aged between 18 and 65; exploratory and confirmatory factor analyses were conducted on the data collected. The confirmatory factor analysis showed that the Japanese version moderately fitted the 4-factor structure of the original REAL scale. However, a 2-factor form obtained in the exploratory factor analysis best fit the data. Consistent with the original version, the Japanese version showed higher RMA in men than in women. The young generation (18–29 years old) self-reported higher RMA than other generations. Japan’s RMA was significantly higher than that of the U.S. sample. The Japanese version of the REAL scale can be used in future studies to assess RMA in Japanese individuals and develop suitable educational programs to reduce RMA.

日本版强奸借口态度和语言量表的发展以及日美强奸神话接受度的比较


接受强奸神话（RMA）是指接受关于强奸受害者、施暴者和强奸行为本身的错误信念、刻板印象和陈述。 RMA 积极预测受害者感到羞耻，消极预测性受害报告。关于性暴力的知识随着时间的推移而变化；因此，测量 RMA 的心理测量量表应该更新。 Hahnel-Peeters 和 Goetz 通过更新伊利诺斯州 RMA 量表（美国使用的主要工具），开发了强奸借口态度和语言 (REAL) 量表。然而，日语中没有 REAL 比例。因此，我们开发并验证了日本版的 REAL 量表，评估了日本人的 RMA（N = 1,000），并将日本参与者的 RMA 水平与 Hahnel-Peeters 和 Goetz 的平均参与者分数进行了比较。与原作者之一合作，通过反向翻译过程开发了日语版本，并针对 1,000 名年龄在 18 岁至 65 岁之间的男性和女性进行了测试；对收集的数据进行探索性和验证性因素分析。验证性因子分析表明，日文版本适度贴合原REAL量表的4因子结构。然而，探索性因子分析中获得的 2 因子形式最适合数据。与原始版本一致，日本版本的男性 RMA 高于女性。年轻一代（18-29 岁）自我报告的 RMA 高于其他一代。日本的 RMA 明显高于美国样本。日本版 REAL 量表可在未来的研究中用于评估日本人的 RMA 并制定合适的教育计划以减少 RMA。
