Postnatal Depression: Brief psychological therapies improve in short-term

  • Mother's Mood
  • Mother-Infant Relationship
  • Child Development

 

Two papers published in the May issue of the British Journal of Psychiatry show that brief home-based psychological therapies for postnatal depression improve the mother's mood, the mother-infant relationship and child behaviour problems in the short term.
 
However, more prolonged treatment may be needed if these improvements are to last.
 
Postnatal depression occurs after about 10% of deliveries. Although it tends to get better spontaneously after 4-6 months, it causes considerable distress and disruption to the women and their families, and affects the quality of the early mother-child relationship as well as the emotional development of the child.
 
The aim of this study was to evaluate the long-term effect of three psychological treatments on these consequences of postnatal depression.
 
193 women with postnatal depression were randomly assigned to one of four conditions: non-directive counselling, cognitive-behavioural therapy (CBT), psychodynamic therapy or routine primary care (the control group). They and their children were assessed immediately after the treatment phase at 4.5 months, and at nine, 18 and 60 months after birth.
 
The study therapists included health visitors who received training in CBT and counselling treatments, as well as specialist professional therapists representing each of the three treatment approaches.
 
Therapy was conducted weekly in the women's own homes from 8- 18 weeks after birth. Eight weeks is the time when postnatal depression is likely to be detected by the primary care team.
 
Effect of treatment on mother's mood:

At 4.5 months symptoms of depression in all three treatment groups had improved significantly compared with the control group.
 
The benefit of treatment was no longer apparent nine months after birth, because the spontaneous remission rate brought the women in the control group to the same point as those in the three treatment groups.
 
Treatment did not reduce subsequent episodes of postnatal depression.
 
Effect on mother-child relationship and child outcome:

At 4.5 months all three treatments had a significant benefit on maternal reports of early difficulties in relationships with the infants. Counselling gave better infant emotional and behaviour ratings at 18 months, and more sensitive early mother-infant interactions, for women experiencing high levels of social adversity.
 
The treatments had no significant impact on maternal management of early infant behaviour problems, security of infant-mother attachment, infant cognitive development or any child outcome at five years.
 
The authors comment that the fact that the three treatments provided only limited, short-term benefits suggests that underlying maternal vulnerabilities persisted. In order to prevent longer-term difficulties, more prolonged interventions may be needed.
 
There was no evidence that specialist therapists were more effective than non-specialist health visitors. Compared with routine care, counselling was the most effective treatment for mother-child relationships and child outcome, and health visitors are well-placed to deliver such support.
 
Health visitors' training and practice should be extended to encompass the detection and management of mothers with postnatal depression
