Online tests for Obsessive Compulsive Disorder can help to determine whether a person should seek professional attention for the disorder, but they cannot make an OCD diagnosis, according to PsychCentral. An OCD diagnosis is only made by a trained health care professional.
OCD is a clinical disorder that induces recurrent obsessions and/or compulsions, notes Mayo Clinic. Online testing assess whether or not an individual has symptoms that are characteristic of the disorder, such as repetitive thoughts, ideas, or impulses. These symptoms can overlap with those of other mental disorders, including anxiety and schizophrenia. A mental health professional is needed to determine whether the symptoms are true markers of OCD and can confirm a diagnosis with lab testing, a physical exam and a psychological evaluation.
