Personality traits have also been explored in high-risk samples. Given the odd, eccentric behaviour of persons with schizophrenia, Squires-Wheeler et al.  hypothesized that certain personality disorders, specifically schizoid, schizotypal and paranoid personality disorders, might be more prevalent in the adult offspring of schizophrenic parents. However, no such aggregation was found . In a later follow-up with the same subjects, all from the New York High-risk Project, an experimental scale derived from the MMPI  was shown to be an effective predictor of schizophrenia-related psychoses . This revised Schizophrenia Proneness scale predicted schizophrenia with over 95% accuracy. Positive predictive power was 40%, negative predictive power was over 97%, sensitivity was 37.5% and specificity was almost 98% . Scores on this scale seem to offer significant promise as a relatively cost effective and efficient predictor, although the researchers caution that further refinement is needed .
