Confirmatory Factor Analysis of the Valencia Scale of Attitudes and Beliefs Toward Hypnosis-client Version in a Portuguese Sample

摘要

Research literature about hypnosis highlights the importance of clients' attitudes and beliefs toward hypnosis because they promote hypnotic responses and may predict the effectiveness of hypnotic interventions as well as minimize iatrogenic effects for clients. This study analyzes the factorial structure and psychometric properties with confirmatory methodology of the Valencia Scale of Attitudes and Beliefs Toward Hypnosis-Client Version, using a Portuguese sample. We expected to replicate the results obtained in previous research conducted with samples from various countries. The Portuguese sample comprised 1,977 participants. We found a structure of 8 factors, with an adequate internal consistency and test-retest reliability. Results are similar to those found in exploratory and confirmatory factor analyses with samples from other countries.
