A concurrent validity study between the Hypnotic Induction Profile (HIP) and the Stanford Hypnotic Clinical Scale for Adults (SHCS:A) in an inpatient sample: a brief report.
The Hypnotic Induction Profile (HIP) is a brief, standardized assessment of hypnotizability which takes 5-10 minutes to administer. The Stanford Hypnotic Clinical Scale for Adults (SHCS:A) is a different clinical measure of hypnotizability that takes about 20-25 minutes to administer. Although both scales purport to measure the same thing, they were based on different theories of hypnosis and constructed using different psychometric techniques. The present investigation is a concurrent validation study comparing scores on the two instruments in a sample of 24 inpatients. The correlation between the SHCS:A and HIP Induction score was 0.41 (p < .01). However, the Eye Roll Sign (ERS) did not correlate significantly with either the SHCS:A (.04, ns) or the HIP-IND score (-.05, ns). These results indicate that while scores on the HIP and SHCS:A are significantly correlated the inter-correlations are not high enough to consider them as interchangeable measures. Implications of these findings for future research are discussed.
