This is a cross-sectional population-based study. The sample was selected in clusters. Mood disorders were assessed using a short, structured diagnostic interview¡ªthe Mini International Neuropsychiatric Interview (MINI) for DSM-IV and ICD-10 psychiatric disorders. Quality of life was assessed by the MOS 36-item Short-form General Health Survey (SF-36).
The sample comprised 1560 young adults. The prevalence ratio of mood disorder episodes were as follows: 10.0 % depressive episode, 2.3 % manic/hypomanic episode, and 2.4 % mixed episode. Lower scores were found in all domains of quality of life among young adults who experience mood disorder episodes when compared to the general population (p<0.001 in the eight domains of the SF-36). Moreover, the impact on quality of life was higher among young adults with mixed episodes, followed by depressive episodes.
Young adults with mood disorders, even without a previous diagnosis of bipolar disorder, have an impaired quality of life in comparison to the general population.
