emotional examples
Anxiety & Distress
OCD is regarded as a particularly unpleasant emotional experience because of the powerful anxiety that accompanies both obsessions and compulsions.
Obsessive thoughts can be frightening or forbidden, these can lead to an urge to repeat a behaviour (compulsion) which in turn creates anxiety.
Accompanying Depression
OCD and depression are often diagnosed together because anxiety can be accompanied by a low mood and lack of enjoyment of activities. Compulsive behaviour tends to bring some relief from the anxiety, but this is only temporary.
cognitive example
People suffering with OCD are usually plagued with obsessive thoughts, but they also adopt cognitive strategies to deal with these.
For around 90% of OCD sufferers the major cognitive feature of their condition is obsessive thoughts that recur over and over again and are usually unpleasant.
cognitive startegies for obsession
Some sufferers of OCD adopt cognitive strategies to deal with their obsessions. For example, suffers with religious obsessions may pray over and over, to reduce their feelings of being immoral.
Furthermore, sufferers of OCD know that their obsessions and compulsions are irrational (insight into their disorder), and experience selective attention directed towards the anxiety-generating stimuli (similar to the selective attention found in phobias).
