A tailored shss.c, permitting user modification for special purposes

In the selection of Ss for the study of specific topics within hypnosis it is often desirable to include a few Ss known to have the specialized ability under investigation. To that end a modification of the Stanford Hypnotic Susceptibility Scale, Form C (SHSS:C) of Weitzenhoffer and Hilgard (1962) has been tested in which one of the original items is replaced at the option of the investigator with an item selected for the purposes of any intended investigation. An empirical test of substituting 4 such items in each of 4 subgroups compared with a standard SHSS:C demonstrated that such a replacement of 1 item by another can be done without violating the usefulness of the established norms on the standardized test. The new form is described as a “tailored” SHSS:C.
