Shame contains external and internal aspects. However, a Japanese language scale for simultaneously assessing both aspects of shame has not been developed to date. This study aimed to standardize the Japanese version of the External and Internal Shame Scale (EISS-J). An online survey was conducted among university students (N = 203) at six universities in Japan (Study 1). A retest questionnaire was sent to the participants by email three weeks after the first survey (Study 2). Study 1 examined the internal consistency, factor structure, and criterion-related validity of the EISS-J, while Study 2 examined its test-retest reliability. Moreover, an additional study was conducted to examine the criterion-related validity of the scale.
Study 1 demonstrated the high internal consistency of the EISS-J. Moreover, confirmatory factor analysis indicated a two-factor model: external and internal shame. However, exploratory factor analysis indicated a three-factor structure. Study 2 confirmed the test-retest reliability of the scale. Furthermore, both studies indicated correlations between the EISS-J and fear of compassion, anger, humiliation, depression, anxiety, and stress. In addition, the study established the criterion-related validity of the scale. These results confirmed adequate reliability and validity of the EISS-J.
羞耻包含外在和内在两个方面。然而，目前还没有开发出一种同时评估羞耻的这两个方面的日语量表。本研究旨在对《外在和内在羞耻量表》（EISS-J）进行日语标准化。在日本的六所大学的大学生中进行了一项在线调查（研究 1）。在第一次调查后的三周，通过电子邮件向参与者发送了一份重测问卷（研究 2）。研究 1 考察了 EISS-J 的内部一致性、因子结构和效标关联效度，而研究 2 则考察了其重测信度。此外，还进行了一项附加研究来检验该量表的效标关联效度。
研究 1 表明 EISS-J 的内部一致性很高。此外，验证性因子分析表明该量表存在外在和内在羞耻两个因子。然而，探索性因子分析表明存在三因子结构。研究 2 证实了该量表的重测信度。此外，两项研究均表明 EISS-J 与同情恐惧、愤怒、屈辱、抑郁、焦虑和压力之间存在相关性。此外，该研究还确定了量表的效标关联效度。这些结果证实了 EISS-J 具有良好的信度和效度。
