The results of the confirmatory factor analysis showed that the factor load of the items is more than 0.15 and all the routes from the items to the variable hidden at the level. 0.5 were significant and the scale had a good construct validity. An examination of the validity of the structure using CFA showed that the scale has a factor structure consisting of 4 subscales. The study of validity at the same time as calculating the correlation of this scale with the scale of attitude with the help of psychological psychologists - Fisher and Farina (1995) short form, Health Anxiety Questionnaire - Salkoskis and Varvik short form (2002), indicates a positive relationship between scale scores.
