Video feedback parent-infant intervention for mothers experiencing enduring difficulties in managing emotions and relationships: A randomised controlled feasibility trial.

Objectives: Parents experiencing mental health difficulties consistent with "personality disorder", often related to a history of complex trauma, may face increased challenges in parent-child relationships and child socioemotional development. There are no published randomised controlled trials (RCTs) evaluating perinatal parent-child interventions for this population. We evaluated the feasibility and acceptability of undertaking an RCT of the video feedback intervention for positive parenting adapted for perinatal mental health (VIPP-PMH).

Design: Feasibility study incorporating a pilot RCT.

Methods: Mothers with enduring difficulties in managing emotions and relationships, consistent with a "personality disorder", and their 6- to 36-month old infants were randomly allocated to receive six sessions of VIPP-PMH (n = 20) or usual care alone (n = 14).

Results: 76% of eligible mothers consented to participate. Intervention uptake and completion rates were 95% (≥1 VIPP-PMH session) and 70% (6 sessions), respectively. Follow-up rates were 85% at month 5 and 65% at month 8 post-baseline. Blinded observer-ratings of maternal sensitivity in parent-child interaction favoured the intervention group at month 5 (RR = 1.94, 95% CI 0.67-5.63) and month 8 (RR = 1.91, 95% CI 0.68-5.33). Small changes over time in self-rated parenting confidence and stress favoured the intervention group. There were no clear intervention effects on maternal non-intrusiveness or mental health, or on child behaviour problems, emotional functioning, or self-regulation.

Conclusions: An RCT of VIPP-PMH is feasible and acceptable to implement with mothers experiencing difficulties consistent with perinatal "personality disorder". A fully powered definitive RCT should be undertaken.
