[Preliminary study of a list of obsessional thoughts. Validation and factorial analysis]

The validation study and factorial analysis of a list of obsessive thoughts is presented. Four groups were compared. They included patients suffering from obsessive compulsive disorders (n = 22), depression (n = 21), phobias (n = 16) and a control group (n = 21). The four groups were comparable as far as age, sex, and educational level were concerned. The list of obsessive thoughts is valid, reliable, and has a good internal consistency. The factorial analysis showed a first factor (accounting for 37.22% of the variance) reflecting perfectionism, and a second factor (accounting for 12.10% of the variance) reflecting a pathological sense of responsibility.
