Objective: This integrative review explores Obsessive-Compulsive Disorder (OCD) from
the perspective of developmental psychopathology, in terms of its multifaceted etiology and course.
Background: Individuals affected by OCD experience intrusive and undesired thoughts accompanied
by behaviors used to mitigate the unwanted images. Accordingly, there are several sub-types
and personality dispositions reflective of the overall continuum of OCD, spanning normality and
psychopathology. The etiology is complex, with generalized psychological and biological vulnerabilities,
as well as contributors from life stress. Moreover, OCD is a disorder with a highly comorbid
and overlapping presence; therefore, difficulties may arise when differentiating between OCD
and other problems.
Conclusion: Treatment non-responsiveness is a pervasive trend in persons afflicted with OCD, but
the most effective approach likely involves a stepped-care model incorporating cognitive-behavioral
psychotherapy and psychotropic medications. Other considerations will also be discussed.
