It is concluded (1) that the index score as a measure of Wechsler-Bellevue scatter empirically derived for this study shows a significant difference between normals (not patients) and neurotics, and between neurotics and psychotics; (2) that an estimate of progressive seriousness of psychological disturbance based on psychiatric diagnosis is reflected in an increased index score for 2 separate hospital populations; and (3) that the index score is an estimate of level of adjustment as evidenced by its ability to discriminate significantly between inpatient neurotics and working outpatient neurotics.Abstract Teaser
