rs, Spearman's rho; CI, Confidence Interval; p, probability; SCL-90-R, Revised Symptom Checklist 90; SPQ, Schizotypal Personality Questionnaire; PAGE-R, Revised Exceptional Experiences Questionnaire. The critical thresholds provided by the FDR procedure (Benjamini and Hochberg, 1995) were 0.077 (α = 0.10, trend), 0.036 (α = 0.05, significant), and 0.006 (α = 0.01, highly significant).
