An American Validation Study of the Newcastle Diagnostic Scale
II. Relationship with Clinical, Demographic, Familial and Psychosocial Features
Published online by Cambridge University Press: 02 January 2018
Abstract
We completed the Newcastle Diagnostic Scale on 152 unipolar depressed in-patients: its validity was supported by the findings that endogenous depressives were, in contrast to neurotic depressives, older, more severely depressed, with better social support, fewer life events, less personality disorder, and a lower morbid risk of alcoholism and antisocial personality in their first-degree relatives. The relationship between Newcastle scores and the morbid risk for alcoholism was non-linear, such that a cut-off score of 4, rather than 5, maximised the difference between the endogenous and neurotic groups with respect to familial alcoholism rates as well as other validating variables.
