The first factor (18 items) had an eigenvalue equal to 14.95 and accounted for 24.9% of the variance and was termed Impaired control over mental activities. Fifteen items that loaded on this factor replicated similar items which loaded on this factor in Sanavios (1980)study. His 14th and 15th items on this factor (nos. 59 and 11) loaded 0.37 and 0.37 on this factor in our study, thus not m

Our results also had three additional items (39, 42, 45). Items 42 and 45 have also loaded on factor 1 in Strenberger and Burnss (1990) study. The second factor (14 items) had an eigenvalue equal to 4.9 and accounted for 8.2% of the variance and was termed Checking Behaviors.
