OCD screening tools focus on intrusive thoughts, checking, washing, ordering, neutralizing, avoidance, and distress. They can help describe symptom areas before professional assessment, but they do not confirm or rule out OCD.
OCI-R is the tool in this category. It explores washing, checking, ordering, intrusive thoughts, hoarding and mental neutralising through 18 questions. The focus is the distress around these experiences, not a preference for neatness alone.
An obsession is an unwanted thought, image or urge that intrudes repeatedly. A compulsion is a repeated action or mental ritual linked to distress or a feeling of necessity. Visible actions such as checking and private mental rituals can both affect daily routines.
For broader worry about everyday matters, see the Penn State Worry Questionnaire in anxiety. For OCI-R, useful context includes how much time a pattern takes, what is avoided and what becomes harder to do. These details explain the experience more clearly than describing oneself simply as a perfectionist.
