| Research Abstract |
The purpose of this study is to investigate the prevalence rate and risk factors on depression among Japanese adolescents. using the DSM diagnostic algorithm. With self-administered questionnaires (the DSD). and semi-structured interviews (the SC ID). two epidemiologic surveys (on school adolescents and on clinical patients) were carried out. For school adolescents (the 8th grade). 238 of the 259 subjects (91.9%) responded in the DSD questionnaires, and 164 of the 191 (85.9%) in the SOID interviews. The 16 subjects were diagnosed as Major Depressive Episode (MDE) by the DSD (the prevalence rate=6.7%), and the 17 (10.4%) by the SOID.These rates were similar to those shown in previous studies. However. the agreement of the MDE diagnosis between the two measures was not so high (kappa=163, n=157). Those in the lower categories for the diagnosis were also low, especially in 'change in appetite/weight' and in 'difficulties in concentration'. In risk assessment for the MDE positives by the DSD, with multiple logistic regression analysis, girls had higher risk than boys did (0dds Ratio=3.3). Feeling that they could not go to school, even if wished to go, was also higher risky (0R=3.1), as well as being bullied in school (0R=3.3). For outpatients in adolescent psychiatry clinic. 34 patients answered for the DSD, and the 14 of them were interviewed on the SOID.Eight patients were diagnosed as MDE by the DSD (the positive rate=23.5%), and seven (50.0%) by the SOID.The agreement on the MDE diagnosis between the two measures in outpatients were relatively higher (kappa=571, n=14) than in general school adolescents. Among the lower categories for the diagnosis, the agreement in 'change in appetite/weight' was low again, but that in 'difficulties in concentration' was quite high. Further studies on these findings will be needed with collecting much more samples on clinical patients and with investigating their medical records.
