There exist reliable and stable trait differences in the ability to control phenomenology in response to imaginative suggestion. Hypnotisability scales measure response to imaginative suggestion within a hypnotic context. Because hypnotisability has recently been shown to predict measures of experiential change in psychological experiments (e.g., the rubber hand illusion), there is a need for easy to use screening tools which are accessible to researchers with little or no background in hypnosis or imaginative suggestion research. The SWASH is a time efficient group hypnotisability scale which can be administered to up to 50 participants simultaneously. Here we present norms from an undergraduate sample for a recorded version delivered by a computer program alongside norms for a live presentation. Reliability, validity and mean scores are similar across the two presentations. Computer delivery of a prerecorded script provides a simple tool to rapidly screen for hypnotisability in large groups for researchers with no prior experience of hypnosis research.
