Table 5presents the factor loadings of each item after Varimax rotation.The first factor (18 items) had an eigenvalue equal
13、to 14.95 and accounted for 24.9% of thevariance and was termed Impaired control over mental activities. Fifteen items that loadedon this factor replicated similar items which loaded on this factor in Sanavios (1980)study. His14th and 15th items on this factor (nos. 59 and 11) loaded 0.37 and 0.37 on
14、 this factor in ourstudy, thus not making the 0.40 criterion (item 59 When I hear about a suicide or a crime, Iam upset for a long time and find it difficult to stop thinking about it, item 11, When doubtsand worries come to my mind, I cannot rest until I have talked them over with a reassuring per-
15、son). Our results also had three additional items (39, 42, 45). Items 42 and 45 have also loadedon 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 thevariance and was termed Checking Behaviors. All the items which
