PIRI has conducted research in the areas of perinatal depression and prematurity since 2001. Our key findings include:

Beating the Blues Before Birth

This paper aimed to evaluate the efficacy of a brief CBT treatment for maternal depression and anxiety in pregnancy. Both the feasibility study and RCT yielded promising results for adherence, acceptability and improvements in depression and anxiety. Strong reductions in anxiety were observed during pregnancy and improvements in depression were maintained at nine months. Infant outcomes showed effects favouring the intervention in domains including problem solving, self-regulation, and stress reactivity, which were independent of maternal postnatal mood.

Subsequent papers have focused on the epigenetic effects of antenatal depression and the effects on children’s brain development:

MumMoodBooster – Online Treatment for PND

Our previous research with MumMoodBooster has established the usability, feasibility and clinical effectiveness of this internet program. Poor uptake of traditional treatment relates to fear of stigma, poor accessibility of clinic-based programs and expense. Potential strengths of a Web-based intervention for PND are accessibility, privacy and low cost. The potential public health impact of Web-based treatment is therefore enormous given the 300,000 annual births in Australia. Our ongoing work continues to evaluate this validated internet intervention for postnatal depression by comparing it to traditional face-to-face psychological treatment. A large randomised controlled trial has been completed and is awaiting publication.

PremieStart: Protecting the Neurological Development of Premature Infants through Stress-Reduction

The primary aim is evaluate the long-term effectiveness of a simple, inexpensive program of stress-reduction for preterm infants (n=123) on measures of cognition and behaviour. We have already demonstrated some early advantages of the PremieStart program in infant development at 6 months and have now compared developmental outcomes at 4 years in intervention and control preterm children, alongside a matched full-term cohort (funded by NHMRC).

We are currently preparing the results of the 6-year and 9-year follow-ups of this preterm cohort.

Beautiful Beginnings: Early Intervention to Facilitate Brain Development in Preterm Infants

The neurological development of premature infants is severely compromised leading to a high prevalence of long-term neurobehavioural problems. In this work we showed that training parents to minimize stress on their premature neonates results in significant enhancements of early brain development, which are observable on cranial MRI scans. Specifically, white matter microstructure and connectivity were improved by this early intervention.

Depression, the Stress of Parenthood & Mother-Infant Interaction

With this paper, we are the first researchers to show that even when PND is treated effectively, this does not reverse the accompanying stress that mediates many of the negative effects of PND on the mother-infant relationship and ultimately infant development. Pilot data suggested that our HUGS mother-infant interaction intervention may be beneficial.

Following on from this work we have now completed 2 RCTs of our HUGS programs which have shown a positive impact of the interventions:

Effective Psychological Treatment for PND

This paper was an RCT comparing cognitive therapy with less specialized psychological interventions. All were demonstrated as superior to conventional routine care. There are relatively few such studies and this one had the added strengths of a broad community sample, formal clinical diagnosis of depression, manualised interventions and well-validated rating instruments.

We subsequently demonstrated in a RCT that our specialised CBT program is at least as effective as treatment with antidepressant medication and can be successfully adapted for delivery by non-specialist health professionals.

Reliable and Acceptable Screening for PND

Before this 2005 paper there had been large screening studies of PND on the one hand and there had been validation studies for PND screening tools on the other. This was the first study to validate a widely used tool in a large representative Australian population against gold-standard diagnostic criteria.

We also published 3 articles evaluating the acceptability of screening. Well-informed Cost-Utility decisions about healthcare screening procedures require several crucial pieces of information including information on the acceptability to patients. This longstanding and important gap in research into perinatal depression screening was addressed comprehensively by the following papers:

Women’s experience of depression and overcoming barriers to seeking help.

This qualitative project was a series of focus groups with women who had been experiencing depression and it concentrated on their acknowledgement of the condition and their journey towards recovery. This is a population that has been shown to be very difficult to engage in services. Of particular relevance were their attitudes and beliefs about their diagnosis and their perceived barriers to care which provide new insight into service design and delivery for women with depression.

Subsequently, we designed and successfully tested a motivational interviewing program that increases rates of help-seeking when delivered by Maternal and Child health Nurses at routine visits:

Towards parenthood: An antenatal intervention to reduce depression, anxiety and parenting difficulties

This paper describes the effectiveness of an antenatal intervention which targeted risk factors for poor postnatal adjustment, with the dual aim of reducing both postnatal symptoms of depression/anxiety and parenting difficulties.
