Thought suppression is a finding from experimental psychology with particularly strong applicability to clinical work. The basic finding is that the harder one tries not to think of something, the more that item intrudes into consciousness. This effect is stronger for thoughts that have emotional content. Thought suppression is a common feature of problems such as obsessive compulsive disorder (OCD) where individuals attempt to suppress intrusive thoughts. Intrusive thoughts (and thought suppression) are also features of other clinical conditions such as PTSD and depression. There is evidence that techniques such as cognitive restructuring, or mindfulness/acceptance are helpful techniques for managing intrusive cognitions. This information sheet gives a simple outline of thought suppression, and the effects of trying to suppress intrusive thoughts.
Thought suppression is most powerfully explained by a demonstration. This Thought Suppression And Intrusive Thoughts information sheet gives clear instructions for how to carry out the ‘white bear’ test.
