Are patients with bipolar affective disorder socially disadvantaged? A comparison with a control group.
BACKGROUND
Bipolar affective disorder (BPAD) has considerable implications for personal and social functioning. However a tendency to be over-represented in high socio-economic classes has been reported in earlier studies, suggesting that social disadvantage accompanying the illness is not severe. In addition, an association between affective disorders in general and increased residential mobility has been suggested, but it is unclear if such an association exists with BPAD.


OBJECTIVE
(1) To investigate the suggestion made in previous studies that patients with bipolar disorder are advantaged socially. (2) To test the hypothesis that patients with bipolar disorder show greater residential mobility compared with other patients with psychiatric disorders.


METHODS
Ninety patients with DSM IV diagnosis of bipolar disorder admitted to the acute in-patient unit of a public-financed district psychiatric service in Dublin were compared with a control group of 91 randomly selected patients with other psychiatric diagnoses, excluding schizophrenia. Socio-economic, educational and employment ratings were compared, and also duration of illness, frequency of admission and residential mobility. The data were collected retrospectively from case notes and through semistructured interviews with patients or their relatives. The bipolar group was compared with the control group and to the unipolar depression subgroup.


RESULTS
The bipolar and control groups were found to have similar demographic and socio-economic features, although the bipolar group had more years of education compared with the whole control group but not when compared with the unipolar depression group. The bipolar group showed longer duration of psychiatric disorder, more frequent hospital admissions and more frequent residential moves since the onset of the illness.


CONCLUSIONS
Bipolar patients requiring in-patient care in this service experience severe disruption to their lives over prolonged periods.
