The relationship of self-reports of hypnotic depth obtained during self-hypnosis to hypnotizability and to the kinds of imagery produced during self-hypnosis is investigated. The sample consisted of 22 highly hypnotizable Ss who practiced self-hypnosis in 1-hour daily sessions for 4 weeks and kept daily journals in which they detailed the contents of their self-hypnosis experiences. The journals were coded for imagery production by scoring for both reality-oriented and primary process imagery. Ss had been taught to monitor their hypnotic depth using a slightly revised version of the Extended North Carolina Scale (ENCS) of Tart (1979). Previously, ENCS has been used only with hetero-hypnotic Ss. The self-reports of depth using ENCS correlated highly with hypnotizability as measured by the Revised Stanford Profile Scale of Hypnotic Susceptibility, Form I of Weitzenhoffer and Hilgard (1967) and with imagery production. Results demonstrate that ENCS scores are also a valid indicator of self-hypnotic depth among highly hypnotizable Ss. Furthermore, they indicate that both hetero-hypnotizability and imagery production are related to self-hypnotic depth, but that the association between imagery and hypnotizability is due to their individual relationships to self-hypnotic depth.
