Waterloo-stanford group scale of hypnotic susceptibility, form c: Manual and response booklet

Abstract

The manual and response booklet for the Waterloo-Stanford Group Scale of Hypnotic Susceptibility, Form C (WSGC) is presented. The WSGC is a group adaptation of the individually administered Stanford Hypnotic Susceptibility Scale, Form C (SHSS:C).

Portuguese Norms for the Waterloo-Stanford Group C (WSGC) Scale of Hypnotic Susceptibility

“…Cronbach's alpha reliability coefficient was .62 in the Portuguese sample and .67 in the SHU sample. Reliability coefficient in the reference samples are .70 as reported by Kirsch et al (1998) and .80 and .81 on two samples as reported by Bowers (1998).…”

“…As a check on this translation, a native English speaker who is fluent in Portuguese translated the scale back into English. The scale administration followed the exact instructions of the original version (Bowers, 1998), with the exception of Item 10 (negative visual hallucination). For this suggestion, instead of placing three balls on a wood platform on the floor, we placed three 20 × 20 cm colored squares on a 60 × 90 cm board.…”

“…However, the SHSS:C is an individually administered scale that takes more than an hour to administer to each participant. To overcome this limitation, the Waterloo-Stanford Group C Scale of Hypnotic Susceptibility (WSGC) was developed by Bowers (1993Bowers ( , 1998 as a group adaptation of the SHSS:C. In the WSGC, a standard eye-closure induction followed by 12 hypnotic suggestions are presented via audiotape. Participants then rate their responses by indicating whether or not they responded behaviorally to the 12 suggestions.…”

Differential patterns of spontaneous experiential response to a hypnotic induction: A latent profile analysis

“…The WSGC is a group adaptation of the individually-administered Stanford Hypnotic Susceptibility Scale, Form C (Weitzenhoffer & Hilgard, 1962) and consists of 12 dichotomously-scored items including direct ideomotor (e.g., arm heaviness), challenge motor (e.g., arm immobilization), and cognitive-perceptual (e.g., auditory hallucination) suggestions, with scores ranging from 0 to 12. This measure has strong psychometric properties (Bowers, 1993(Bowers, , 1998.…”

“…Finally, we tested the prediction that the experiential response patterns of the derived profiles would correspond to those predicted by the bifurcated and trifurcated dissociative typological models (Barber, 1999a;Barrett, 1996;Cardeña, 1996;Carlson & Putnam, 1989;Perry, 2004). Bowers, 1993Bowers, , 1998) was used to measure responsiveness to hypnotic suggestions. The WSGC is a group adaptation of the individually-administered Stanford Hypnotic Susceptibility Scale, Form C (Weitzenhoffer & Hilgard, 1962) and consists of 12 dichotomously-scored items including direct ideomotor (e.g., arm heaviness), challenge motor (e.g., arm immobilization), and cognitive-perceptual (e.g., auditory hallucination) suggestions, with scores ranging from 0 to 12.…”
