Step 1 of 2

  • General Instructions

    This rating scale is designed to rate the severity and type of symptoms in patients with obsessive compulsive disorder (OCD). Rate the characteristics of each item during the prior week up until and including the time of the interview. Scores should reflect the average (mean) occurrence of each item for the entire week.

  • Check all that apply, but clearly mark the principal symptoms with a "P", (Rater must asertain whether reported behviors are bona fide symptoms of OCD, and not symptoms of another disorder such as Simple Phobia or Hypochondriasis. Items maried "*" may or may not be OCD phenomena.)

    Questions 1 to 5 are about your obsessive thoughts Obsessions are unwanted ideas, images or impulses that intrude on thinking against your wishes and efforts to resist them. They usually involve themes of harm, risk and danger. Common obsessions are excessive fears of contamination; recurring doubts about danger, extreme concern with order, symmetry, or exactness; fear of losing important things.

    The five questions of obsessions remain

  • “Obsessional thoughts" refers to unpleasant, unwanted, and intrusive thoughts/images that keeps appearing in your mind. You don't want these thoughts/images, but you can't control it. They always go against your wishes. When you have these thoughts/images, you feel highly anxious.
  • Explain: When obsessions occur as brief, intermittent intrusions, it may be difficult to assess time occupied by them in terms of total hours. In such cases, estimated time by determining how frequently they occur. Consider both the number of times the intrusions occur and how many hours of the day are affected. Ask yourself: How frequently do the obsessive thoughts occur?
  • In other word: What is the longest block of time in which obsessive thoughts are absent?
  • Explain: If currently not working, try to determine how much performance would be affected if you were employed.
  • Explain: In most eases, distress is equated with anxiety; however, you may report that your obsessions are "disturbing" but not "anxiety." Only rate anxiety that seems triggered by obsessions, not generalized anxiety or associated with other conditions.
  • Explain: Only rate effort made to resist, not success or failure in actually controlling the obsessions. How much you resist the obsessions may or may not correlate with your ability to control them.
  • Explain: In contrast to the preceding item on resistance, the ability of the patient to control your obsessions is more closely related to the severity of the intrusive thoughts.
