In recent years the number of individuals diagnosed with obsessive compulsive disorder (OCD) has increased. With a life time prevalence of 2.5%, OCD is more prevalent than schizophrenia, bipolar disorder, or panic disorder. Undiagnosed and untreated, OCD can have negative effects on many aspects of an individual's life, including vocation. With the mean age of onset in the United States being approximately 16 years of age, the impact of OCD on an individual's vocational development can be considerable. Additionally, individuals with this disorder may present a poor work or academic history. Their vocational performance may be incorrectly interpreted as indicative of irresponsibility or a poor work ethic rather than as a consequence of the disease. Therefore, rehabilitation counselors should be cognizant of the symptoms associated with OCD and the negative impact of the disorder on an individual's life. This article outlines symptoms of the disorder, explores current treatment options, and discusses vocational implications associated with OCD.
