Rates of depressive and anxiety disorders in a residential mother-infant unit for unsettled infants.

OBJECTIVE: Depression and anxiety are known to be common among women presenting to residential mother-infant programmes for unsettled infant behaviour but most studies have used self-report measures of psychological symptomatology rather than diagnostic interviews to determine psychiatric diagnoses. The aim of the present study was to determine rates of depressive and anxiety disorders and rates of comorbidity among clients of the Karitane residential mother-infant programme for unsettled infant behaviour.
METHOD: one hundred and sixty seven [corrected] women with infants aged 2 weeks-12 months completed the Edinburgh Postnatal Depression Scale and were interviewed for current and lifetime history of depressive and anxiety disorders using the Structured Clinical Interview for DSM-IV diagnosis (Research version).
RESULTS: A total of 25.1% of the sample met criteria for a current diagnosis of major depression, 31.7% had met criteria for major depression since the start of the pregnancy, and 30.5% of clients met criteria for a current anxiety disorder. Of note were the 21.6% who met criteria for generalized anxiety disorder or anxiety disorder not otherwise specified (worry confined to the topics of the baby or being a mother). High levels of comorbidity were confirmed in the finding that 60.8% of those with an anxiety disorder had experienced major or minor depression since the start of their pregnancy and 46.3% of those who had experienced depression since the start of their pregnancy also met criteria for a current anxiety disorder.
CONCLUSIONS: There are high levels of psychiatric morbidity among clients attending residential mother-infant units for unsettled infant behaviour, highlighting the importance of providing multifaceted interventions in order to address both infant and maternal psychological issues.
