Note: Summaries of key demographic variables, meditation experience and positive psychotic symptoms (*Clinical cut-off 50). Participants could complete the whole survey or only parts of the survey. For each hypothesis, the following number of datasets were available: H1a+H1c+H2a –n = 613 (Questions about meditation practice and PLE symptoms); H4: n = 180 (Included only those who completed the Mystical Experiences questions); H3a: n = 155 (“Psychosis proneness Qus”, i.e. additionally completed questions about risk factors for psychosis). For the purposes of testing the pre-registered hypotheses, we considered a participant to have completed the whole survey to be those who completed it up to the end of the psychosis proneness measures, the last one being the Aberrant Salience Inventory (n = 155). For ’Participants Who Endorsed’ this represents how many picked 1 or more technique relating to each meditation method. The mean score and standard error for the main psychosis symptom measure (CAPE-42 positive subscale) was 29.55 (0.3), well under 50, the clinical threshold to detect undiagnosed first episode psychosis [73]. 16 participants were above this threshold of 50. ‘Immigration Status: Born in Country’ is a measure of how recently people have moved to their country of residence.
