Resum:
© 2018 Elsevier B.V. The aim of the study was to investigate the current prevalence of DSM-5 Depressive Disorders (DD) among Spanish school children and compare it with data obtained 20 years ago from the same place. We assessed comorbidity, severity and sociodemographic related factors. With a double-phase design, a sample of 1514 students participated in the 1st phase and 562 students (175 at risk of depression) were assessed in the 2nd phase with the Mini-International Neuropsychiatric Interview for Kids. The estimated current prevalence of Major Depressive Disorder (MDD) was 1.6%, similar to the 1.5% found 20 years ago. A total of 3.4% were diagnosed with some form of DD (MDD or Persistent Depressive Disorder (PDD)). No significant differences between genders were found in either of the two periods studied. The rate of depressive symptoms (11.6%) was not significantly different from that of previous data (9.4%). 80% and 71.9% of the children diagnosed with MDD and PDD respectively also had an anxiety disorder. In conclusion, we have not found an increase in depression among Spanish early adolescents. However, the data on the prevalence of DD, the comorbidity, and the impairment all highlight the need to design and implement appropriate preventive interventions in schools.
