ABSTRACT: The purpose of this study
was to examine whether a broadobsessive-compulsive
and related disorders model, which consisted of obsessive-compulsive, hoarding
disorder, body dysmorphic, trichotillomania and pathological skin picking,
displayed sufficient data fit. On the other hand, we examined whether a reduced
obsessive-compulsive and related disorders symptoms model consisting of above
mentioned disorders demonstrated superior fit or not. To test the factor
structure validity of the classification system of obsessive-compulsive
spectrum disorders, we used Confirmatory Factor Analyses (CFA). Result of
factor structure analysis revealed and supported an OCSD symptoms dimension
that included obsessive-compulsive, hoarding disorder, body dysmorphic,
trichotillomania, and pathological skin picking symptoms. Also, results of this
study supportedthe DSM-5
changes.
