This study examined the prevalence and clinical features of ICD-10-defined neurasthenia (NT) in Chinese-Americans and its relations to other psychiatric disorders.
In this community epidemiological survey, the enhanced Composite International Diagnostic Interview (CIDI), with a supplemental NT module, was administered to 1,747 Chinese-Americans, selected with a stratified cluster sampling method.
The SCL-90-R was also used for measuring psychiatric morbidity and symptoms.
Dimensions of social stress and social support were measured by established instruments.
A total of 112 ICD-10 NT subjects (6.4%) were identified.
Of these, 63 (56.3%) did not experience any current and lifetime DSM-III-R diagnoses, yielding a 12-month or lifetime prevalence rate of « pure » NT of 3.61%. This rate was much higher than any of the other psychiatric disorders in this sample.
Compared with normal subjects, « pure » NT subjects had significantly higher SCL-90-R total and factor scores, experienced more psychosocial stress, and perceived less social support (P<. 05 or. 01).
Compared with subjects with depression and anxiety disorders, « pure » NT cases reported significantly less SCL-90-R psychological symptoms (P<. 05 or. 01), but had a strikingly similar elevation in the somatization subscale score.
These data suggest that NT is a distinctive clinical condition overlapping only partially with the other better recognized diagnostic entities. (...)
