The data from 77 studies that examined the relationship between the Tellegen Absorption Scale (TAS) and hypnotic susceptibility were used in a meta-analysis that investigated whether defining the context as hypnotic has a significant impact on this correlation. These studies yielded 187 correlations between a hypnotic susceptibility scale and the TAS.

Studies were coded on the following factors: Year of publication, publication status, type of hypnotic susceptibility scale; whether the TAS was measured in or out of a hypnotic context; and whether the hypnotic context was established before or after TAS assessment, or not at all.

There was a moderate relationship between hypnotizability and the TAS, overall sample weighted mean r = .25. The type of hypnotic susceptibility scale had a significant impact on the magnitude of the TAS and Hypnotizability relationship. Mean sample weighted correlations ranging from .23 for the Carleton University Responsiveness to Suggestion Scale (CURSS) to .41 for the Hypnotic Induction Profile (HIP)

Except for studies using the CURSS, there was no statistically signficant differences between those studies that established a hypnotic contextual, or those that did not for most of the susceptibility scales. However for the CURSS, the Hypnotizability TAS relationship was significantly lower when no hypnotic context was established, than when the context was defined as involving hypnosis.

Based on these results, variations in the size of the relationship between hypnotic susceptibility and the TAS are most likely due to the type of hypnotizability scale used in the study, and to sampling and measurement error rather than to any contextual influence on this relationship.
