The spectrum of severity and the need to test treatments for OCD underlines the importance of reliable and valid scales when it comes to rating the symptoms. It needs to be sensitive to the slight changes in severity and frequence of both obsessions and compulsions, and currently only one scale seems to encompass this definition - the Yale Brown Obsessive Compulsive Scale, or Y-BOCS.
There are two other rating scales used in the diagnosis and treatment of OCD - the Maudsley and the Leyton Obsessive Compulsive Inventories, but these depend on self rating and confound measurement of trait with other variables. The Y-BOCS is not influenced by the number or type of obsessions and compulsions, and rather than cataloguing the symtoms experienced, it analyses the impact on the sufferer's life and the resulting anxiety.
The intended use of the Y-BOCS is the quantification of symptom severity in patients diagnosed with OCD and their response to treatment - it is not designed as a diagnostic test. Symptoms are assessed with regard to the amount of time spent daily on obsessions and compulsions, the interference that this provokes, the subjective distress that is caused and the resistance that the sufferer is able to show when faced with both are measured on the scale.
At the end of the day, no scale is perfect, but I think that the Y-BOCS is an efficient tool for the monitoring of progress - by applying the scale every now and then, it is possible to see even the smallest of steps, and I think that's important.
