title: Quality of life in children with OCD before and after treatment.
abstract: Quality of life (QoL) is a well-established outcome measure. In contrast to adult obsessive-compulsive disorder (OCD), little is known about the effects of treatment on QoL in children with OCD. This study aimed to assess QoL after cognitive behavioural therapy (CBT) in children and adolescents with OCD compared with the general population and to explore factors associated with potential changes in QoL after treatment. QoL was assessed in 135 children and adolescents (ages 7-17; mean 13 [SD 2.7] years; 48.1% female) before and after 14 CBT sessions, using self-report and a caregivers proxy report of the Questionnaire for Measuring Health-related Quality of Life in Children and Adolescents (KINDL-R). QoL was compared with an age- and gender-matched sample from the general population. Before treatment, QoL was markedly lower in children with OCD compared with the general population. QoL improved significantly in CBT responders (mean score change 7.4), to the same range as QoL in the general population. Non-responders reported no QoL changes after treatment, except for one patient. Comorbidity, family accommodation and psychosocial functioning were not associated with changes in QoL after treatment. To our knowledge, this is the first study of the changes in QoL after treatment of paediatric OCD. The assessment of QoL beyond symptoms and function in children with OCD has been shown to be reliable and informative. The results of this study support the application of QoL assessment as an additional measure of treatment outcome in children and adolescents with OCD.
