The operating characteristics of the Center for Epidemiologic Studies Depression Scale were compared between Japanese and U.S. adult workers. Data were analyzed from age- and education-matched male white collar workers (n = 368 for each) selected from 2016 workers in Japan and 3059 in the United States. The U.S. data were obtained from the 1974-75 Augmentation Survey of the National Health and Examination Survey I. The Japanese responses to positively worded items markedly differed from those of U.S. workers, whereas responses to negatively worded items were generally comparable in the two groups. Thus, spuriously higher positive subscale and whole scale scores were found among the Japanese workers compared with U.S. workers (mean scores: 6.03 vs. 1.83 for the positive subscale and 9.94 vs. 5.35 for the whole scale, respectively; both differences were statistically significant). Negative subscale scores did not differ significantly in the two samples (3.91 vs. 3.52). The present study confirmed the hypothesis of Iwata et al. that Japanese respondents have a tendency to suppress the expression of positive affect.
对日本和美国成年工人的流行病学研究中心抑郁量表的操作特征进行了比较。数据来自年龄和教育程度匹配的男性白领工人（日本2016名工人中选取368名，美国3059名工人中选取368名）。美国的数据来自1974 - 75年全国健康与检查调查I的增强调查。日本工人对正向表述项目的回答与美国工人明显不同，而对负向表述项目的回答在两组中总体相当。因此，与美国工人相比，日本工人的正向子量表和总量表得分出现了虚假的更高分数（平均得分：正向子量表分别为6.03对1.83，总量表分别为9.94对5.35；两者差异均具有统计学意义）。两个样本的负向子量表得分没有显著差异（3.91对3.52）。本研究证实了岩田等人的假设，即日本受访者倾向于抑制积极情绪的表达。
