Scoring & interpretation
Each question is rated on a scale of frequency (never to very often), perceived distress (none to extreme), and difficulty of control (none to extreme). The scores are totaled to provide an overall measure of the frequency and impact of obsessional intrusions. Scoring cutoffs can be used to identify clinical profiles.
