Abstract

Objectives: To investigate OCD symptom structure
in children and adolescents in order to identify OCD
subtypes.
A few studies have tried to identify symptom based
subtypes of OCD in Children and Adolescents, and
found it to contain 4-5 factors. There are several
reasons for the different number of factors found
such as different methods and limited sample sizes.
Therefore, this study based on a large sample will be
a valuable addition to the previous studies.
Methods: Exploratory factor analysis will be applied
to the Children’s Yale-Brown Obsessive-Compulsive
Scale (CY-BOCS) symptom checklist items in order
to reveal any latent factor structure. The relation
between specific factors and co-morbid disorders will
be examined. Data for 696 children and adolescents
with OCD is already collected and the final sample is
expected to be around 850 subjects, collected from
24 different research units in Europe and USA. This
study is a part of the Nordic Long-Term OCD
Treatment Study (NordLOTS).
Results: Work in progress. Preliminary results will be
available at the time of presentation.
Discussion: Our study is unique in that it includes
individual CY-BOCS checklist items and it is thus
possible that our results will refine or go beyond the
“classical” factors in the original publication. The
importance of our findings for studies on OCD
genetics and pathogenesis of symptoms will be
discussed.
