Checking Certainty And Doubt
Checking, certainty, and doubt is an information sheet about a maintenance mechanism important in obsessive compulsive disorder (OCD). It includes a description of checking, and a summary of recent research which indicates that increased checking leads to decreased trust in memories. The information sheet also includes a suggestion for a behavioral experiment so that clients can explore the operation of this mechanism in their own lives.
This tool can be given to clients as psychoeducational information. Many clients will find it more effective, however, to attempt the included behavioral experiment and to discover for themselves the effects of checking upon certainty.
