The Hamilton Anxiety Scale. Evaluation of homogeneity and inter-observer reliability in patients with depressive disorders.
In the present study the Hamilton Anxiety Scale (HAS), originally constructed for patients with neurotic anxiety, has been applied to patients with diagnosis of depressive disorders. The inter-rater reliability and homogeneity are evaluated and total scale score has been correlated to the Bech-Rafaelsen Melancholia Scale (BRMES). Twenty-two patients entered the study, 13 with endogenous depressions, and 9 with non-endogenous depressions when classified according to the ICD-8. For both scales the inter-rater reliability was found statistically significant. Concerning the homogeneity of the HAS, statistical significance was obtained for 7 items reflecting psychic anxiety, whereas in the BRMES statistical significance was found in all items apart from 2. Total scale score on HAS correlated positively with total score on BRMES for all 2 patients. However, when the patients were classified according to the ICD-8 this correlation seemed to be due to the endogenously depressed group as no significant correlation was seen for the group of non-endogenous depression. On the other hand, when the patients were classified according to the MULTI-CLAD system no significant intercorrelation of the HAS and BRMES scores was found within the subtypes of depression.
