Response patterns on the Center for Epidemiologic Studies Depression S
cale (CES-D) items among Japanese adolescents were compared with those
of their U.S. counterparts. The data were obtained from approximately
1,500 junior high school students, aged 12-15 years. Japanese respons
es to positively worded items markedly differed from those of American
adolescents, whereas responses to negatively worded items were compar
able in the two groups. This resulted in poor psychometric properties
for the CES-D and spurious higher positive subscale and whole scale sc
ores among the Japanese sample. It is possible that Japanese responden
ts tend to suppress positive affect expression and, thus, the positive
ly worded questioning is presumably inappropriate for Japanese samples
.
