I check things more often than necessary

I get upset if objects are not arranged properly

I feel compelled to count while I am doing things

I find it difficult to touch an object when I know it has been touched by strangers or certain people

I find it difficult to control my own thoughts

I collect things I don't need

I repeatedly check doors, windows, drawers, and so on

I get upset if others change the way I have arranged things

I feel that there are good and bad numbers

I wash or clean myself more than necessary

I am upset by unpleasant thoughts that come into my mind against my will

I avoid throwing things away because I am afraid I might need them later

I repeatedly check gas and water taps and light switches after turning them off

I need things to be arranged in a particular order

I have nasty thoughts and have difficulty getting rid of them

I wash my hands more often and longer than necessary

I need to repeat certain actions until I feel it is right
