Differentiating Subtypes of Postnatal Depression Based on a Cluster Analysis of Maternal Depressive Cognitions

: Based on the analysis of cognitive style, this study demonstrated that
women experiencing postnatal depression (PND) fall into two categories: (a) those with
a general cognitive vulnerability to depression and for whom childbirth is a non-specific
stressor; and, (b) those whose depression is directly related to the stressful demands of
motherhood. Studying an Australian sample of 406 postnatal women who completed the
Edinburgh Postnatal Depression Scale (EPDS), the Dysfunctional Attitudes Scale (DAS24), and the Maternal Attitudes Questionnaire (MAQ), hierarchical cluster analysis
identified three groups distinguished on the basis of depressive symptomatology and/or
the nature and strength of maladaptive cognitions.
