In psychopathology, an obsessive compulsive disorder (OCD) is a type of chronic disorder in which a person has uncontrollable, reoccurring thoughts (obsessions) and/or behaviors (compulsions) that he or she feels the urge to repeat over and over.

The person who has an OCD usually repeats these behaviors in order to stop the recurring thoughts that make the person feel discomfort and anxiety.

In this example, Renette has not been able to paint her bathroom because every time she paints a wall, she uses a magnifying glass to ensure that the job is perfect and if it's not, she will strip the paint off and start again. She is having the thought that the painting should be perfect and if it's not, she probably feels anxiety and she has the behavior of stripping the paint off. Thus, she is demonstrating the symptoms of obsessive-compulsive disorder.
