Control variables include age, sex, and education. Emotional instability was assessed using the anger-hostility subscale of the SCL-90-R. Two outliers were removed from the model predicting interpersonal sensitivity, seven from the model predicting emotional instability (anger-hostility), and one from the model predicting additional items. 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.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.
