Extract

A psychotic v. neurotic scale has been presented in the manual of the Symptom-Sign Inventory (Foulds and Hope, 1968). This scale was constructed after comparing each of four female neurotic groups with each of four female psychotic groups and each of four male neurotic groups with each of four male psychotic groups. For an item to be included in the scale 14 of the 16 comparisons within each sex had to show differences significant at least at the 5 per cent. level. On 18 items the psychotic groups had frequencies in excess of the neurotic; on only one item was it the other way round. The scale score is the sum of these 18 items minus the one.
