In this study, we compare the rates of psychiatric disorders found among
women in a random sample of the general population with those of patients
referred to specialist services. Both these groups were drawn from the same
geographical area. The ratio of prevalence rates is less than the ratio
between inception rates in the two groups. When only those with affective
disorders were considered, the results revealed that the point prevalence
in the treated-disorders group was only 1% of the community-group
prevalence, while the inception into care in the former group was nearly 6%
of that in the latter. Single women and older women were over-represented
in the hospital sample.
