The Development and Use of the Valencia Scales of Attitudes and Beliefs Toward Hypnosis.

The importance of attitudes and beliefs in relation to people's behavior, both in general and within the context of psychological treatment, is undeniable. This is especially true in the field of hypnosis, where misinformation and myths are widespread. In response to a request from, and as a tribute to, Professor Steven Jay Lynn, we summarize the status of the Valencia Scales of Attitudes and Beliefs toward Hypnosis, both the client (VSABH-C) and therapist (VSABH-T) versions. A literature review was conducted in May 2024 across nine databases. The only inclusion criterion was that the studies had to cite and/or use either or both versions of the VSABH scales as a measurement instrument. A total of 73 references were selected and classified into four categories: psychometric analyses, use of the scales, citations, and unpublished references. The findings indicate that the VSABHs are widely used, useful, robust, and versatile scales with international projection, and its 37-item version is recommended. Scholars and practitioners are encouraged to continue the psychometric and applied study of these scales and to undertake adaptation processes in different languages, cultures, and samples, adhering to the guidelines set forth by the International Test Commission (ITC) rather than relying solely on reverse translations.
