Control variables include age, sex, and education. Five outliers were removed from the model predicting phobic anxiety, three from the model predicting obsessive-compulsive symptoms, and one from the model predicting somatization. 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 0.030 (α = 0.10, trend), 0.013 (α = 0.05, significant), and 0.001 (α = 0.01, highly significant). Significant values are in boldface, statistical trends in italics.
