| Abstract: | The DSM‐IV and ICD‐10 are both operational diagnostic systems that classify known psychological disorders according to the number of criteria symptoms. Certain discrepancies between the criteria exist and may lead to some inconsistencies in psychiatric research. The purpose of this study was to investigate these differences in the assessment of depression with item response theory (IRT) analyses. The World Mental Health‐Japan (WMHJ) Survey is an epidemiological survey of the general population in Japan. We analyzed data from the WMHJ completed by 353 respondents who had either depressive mood or diminished interest. A two‐parameter logistic model was used to evaluate the characteristics of the symptoms of the DSM‐IV and ICD‐10. IRT analyses revealed that the symptoms about psychomotor activity, worthlessness and self‐reproach were more informative and suggestive of greater severity, while the symptoms about dietary habits were less informative. IRT analyses also revealed that the ICD‐10 seems more sensitive to the mild range of the depression spectrum compared to the DSM‐IV. Although there were some variations in severity among respondents, most of the respondents diagnosed with a severe or moderate depressive episode according to the ICD‐10 were also diagnosed with a major depressive episode according to the DSM‐IV. |
