Validity of the Fear Survey Schedule in phobia research: A laboratory test

The Fear Survey Schedule III, developed by Wolpe and Lang (1969, 1977), is used frequently to classify subjects as phobic or nonphobic. Subjects selected for their intense-fear scores on blood, fire, bat, and snake items did not significantly differ from no-fear subjects on an objective behavioral assessment test. Analyses of subject verbal reports suggest several possibilities for the inability to discriminate between fearful and nonfearful subjects. Researchers are cautioned about the use of the Fear Survey Schedule for selecting phobic subjects without supporting evidence.
