Postnatal depression affects 10-15% of all mothers but in many cases i
t is undetected and untreated. This paper explores two aspects of mate
rnal thinking in postnatal depression which might affect detection and
treatment. Firstly, it reviews the evidence that there are cognitive
differences between women in the postnatal period and that the vulnera
bility to depression postnatally for some women may reflect a particul
ar cognitive style. Secondly, it examines women's perceptions of their
symptoms, relating these to whether they seek help and accept treatme
nt. The importance of maternal thinking in the treatment of postnatal
depression, particularly by health visitors is discussed.
