Abstract:Obsessive-compulsive disorder(OCD)is a severe chronic mental illness with a rather high cure rate. However, a high percentage of sufferers actually have not received proper treatment in time. An in-depth analysis of the factors resulting in a retarded treatment of the disease finds that the following factors have all played a part, such as the individual characteristics of the patient, the wrong concept about the illness on the part of the patient, the demographical variables and factors related to treatment. Easier access to quality psychological health care service, to develop more tools for checking and screening the illness, the popularization of OCD-related information, the optimization of current treating methods and finding more effective treating approaches may help the patients obtain timely and proper treatment. Future research can further identify the retarding factors and thus help find pointed coping strategies.
