Improving help-seeking for postnatal depression and anxiety: a cluster randomised controlled trial of motivational interviewing
Low uptake of treatment by women with symptoms of postnatal depression and anxiety is consistently reported. This study examined whether a brief motivational interviewing (MI) intervention delivered by Maternal and Child Health Nurses (MCHNs) during routine emotional health assessments improves help-seeking following childbirth. In this parallel two-group cluster randomised controlled trial, MCHNs delivered a MI intervention (‘PRIMER’, n = 20) or Routine Care (n = 20) at women’s (n = 541) postnatal consultations. The primary outcome was help-seeking over the 12 months post-birth. Other outcomes were emotional distress measured by the Edinburgh Postnatal Depression Scale, Beck Depression Inventory-Revised and Depression Anxiety Stress Scales, and barriers to help-seeking obtained by self-report via a checklist of potential barriers that was presented to women to select from if applicable. 27.4% of the sample experienced emotional distress over the 12 months post-birth. When comparing women who experienced emotional distress with those who did not, odds of seeking help were 4.0 times higher for the MI condition than Routine Care (p = .004). Of the women who sought help from a psychologist, 47.6% in the MI condition attended 6 + sessions versus 20.0% in Routine Care (numbers too small for reliable significance test). There was a non-significant trend of lower depression, anxiety and stress in the MI condition. Three risk factors for postnatal depression predicted help-seeking: antenatal anxiety (OR = 2.8, p = .002), depression history (OR = 2.5, p = .002) and self-esteem (OR = 0.7, p = .04). Common barriers to seeking help were thinking that one would or should be able to manage without help (endorsed by 11.1%). Treatment uptake for postnatal distress can be increased with MI. Training MCHNs in MI was feasible and valued. Given the devastating effects of depression, further research is needed to ascertain whether MI can improve mental health outcomes.
