The present study was designed to test Frankel and Orne's hypothesis that persons with a clinically significant phobia also show high susceptibility to hypnosis. The hypnotic susceptibility scores of 10 persons who sought treatment with hypnosis for agoraphobia were compared with the susceptibility scores of a control group of 20 persons having comparable motivation to succeed in hypnosis. The susceptibility measure was the Stanford Hypnotic Susceptibility Scale: Form C (SHSS:C, Weitzenhoffer & Hilgard, 1962). The groups were also compared on: a) the Archaic Involvement Measure (AIM; Nash, 1984); b) the Field Depth Inventory (FDI; Field, 1965); and c) the Tellegen Absorption Scale (TAS; Tellegen & Atkinson, 1974). No significant differences were found between the groups on the dependent measures. Factors which qualify the results are discussed.
