Note: N = 105. CAPE Biz. Exp. and Perc. Ab. were transformed via rank-based inverse-normal transformation to correct nonnormality. CAPE = Community Assessment of Psychic Experiences; SIPS = Structured Interview for Psychosis-Risk Syndromes; Psychosis-proneness = Psychosis Questionnaire-Brief Version; Hallucination-proneness = Launay-Slade Hallucination Scale; Depression = Beck Depression Inventory-II; Anxiety = Beck Anxiety Inventory. 95% confidence intervals shown in brackets.
SIPS symptom scores are ordinal data. For consistency, they are presented here with parametric statistics. We also tested them with non-parametric statistics (Spearman’s correlations). Results did not meaningfully differ. Nonparametric results with medians and IQRs are provided in the supplemental material, Table S1.
