PROBLEM Several recent studies('* 2 , 3 , 4 , have investigated aspects of Wolpe and Lang's") Fear Survey Schedule (FSS), which was developed originally for use in planning the course of behavior therapy in cases of phobic fears. They classified the items of the inventory into six subclasses : animal, social or interpersonal, tissue damage, noises, other classical phobias, and miscellaneous. They indicated that sometimes arbitrary decisions had to be made about placement of some items in the six categories and that the classification was given to facilitate clinical use and was in no sense definitive. They also indicated they were planning a formal statistical analysis of the scale.Two factor analysesc5* 6 , of the FSS have appeared in the literature. However, both used nonpsychiatric populations (namely, introductory psychology students). This paper reports a factor analysis of the FSS on a psychiatric population.
METHODSubjects. Ss were 100 inpatients of a psychiatric institute, including 50 males and 50 females. The age range was from 16 to 60 years; mean age for males, 30.7 years; for females, 32.0 years. As measured by t test, this difference was not significant. None of the patients had demonstrable organic brain damage. Otherwise, the patients were not selected, but rather constituted the first 50 male and first 50 female referrals for psychological testing to be received by the psychology department after the FSS was introduced.The FSS. The newer and more extensive revision(8) was employed. It consists of 76 discrete items. Each S read, or had read to him, the following instructions:
