Previous issue date: 2014-12-05 / Obsessive-compulsive disorder (OCD) is a chronic mental illness that causes major suffering and affects quality of life (QoL). Depressive symptoms (DS), in turn, have shown to be highly prevalent in patients with OCD. Notwithstanding, it remains unclear whether QoL impairment is a result of OCD or DS. Likewise, the impact of DS on the QoL of adolescents with OCD has not been sufficiently explored. This dissertation comprises two empirical population-based studies: 1) the first study assessed whether the presence or absence of DS in adolescents with and without OCD was associated with QoL; 2) the second study measured the effect size of DS on the QoL of adolescents with OCD. Results showed that patients with DS, regardless of the presence or absence of OCD, show lower QoL scores in the physical health, psychological, and social relations domains, and also lower total scores; no significant differences were found between the groups in the environment domain. Furthermore, results showed that the combination of DS and OCD presented moderate to high effect sizes (0.66 to 1.97), indicating statically significant QoL impairment in adolescents with DS. These findings allow us to conclude that QoL is poorer when DS are present, regardless of the presence of absence of OCD. Moreover, the co-occurrence of DS in adolescents with OCD results in statistically significant impairment in all QoL domains. / O transtorno obsessivo-compulsivo (TOC) ? considerado um transtorno mental cr?nico que causa acentuado sofrimento e interfer?ncia na qualidade de vida (QV). Os sintomas depressivos (SDs), por sua vez, apresentam alta preval?ncia junto ao TOC. No entanto, a literatura n?o esclarece se o preju?zo na QV se d? em fun??o do TOC ou dos SDs. Da mesma forma, o impacto dos SDs na QV de adolescentes com TOC n?o foi suficientemente estudado. A presente disserta??o ? composta por dois estudos emp?ricos de base populacional: 1) o primeiro estudo verificou se a presen?a ou aus?ncia de SDs em adolescentes com e sem TOC est? associada ? QV; 2) o segundo estudo mensurou o tamanho do efeito dos SDs na QV de adolescentes com TOC. Os resultados apontam que os grupos com SDs, independentemente de terem ou n?o TOC, apresentaram pior QV nos dom?nios f?sico, psicol?gico, rela??es sociais e no escore total; n?o houve diferen?a significativa entre os grupos no dom?nio meio ambiente. Al?m disso, o efeito da adi??o dos SDs ao TOC teve, como resultados, tamanhos de efeitos que variaram de moderados a grandes (0,66 a 1,97), indicando preju?zos estatisticamente significativos em rela??o ? QV em adolescentes com SDs. Esses achados permitem concluir que h? pior QV quando os SDs est?o presentes, independentemente de haver ou n?o TOC. Al?m disso, a adi??o de SDs em adolescentes com TOC provoca preju?zos estatisticamente significativos em todos os dom?nios da QV.
