摘要：This co‐registered Cochrane and Campbell systematic review compares the effectiveness of parent‐infant psychotherapy (PIP) in improving the mental health of parents, the parent‐infant relationship and infant emotional wellbeing with that of no treatment, treatment as usual and alternative treatments. The review summarises findings from eight randomised controlled trials (RCTs), with a total of 846 participants. Compared with no treatment or treatment‐as‐usual, PIP participants show an increase in the number of infants securely attached; fewer infants with an avoidant or disorganised attachment style; and more infants moving from insecure to secure attachment. This was maintained at follow up. PIP is neither more nor less effective than no treatment or treatment‐as‐usual in improving maternal mental health, and reflective functioning; infant stress and development; or the quality of the mother‐infant interaction. Parent‐infant psychotherapy (PIP) is a dyadic intervention that works with parent and infant together, with the aim of improving the parent‐infant relationship and promoting infant attachment and optimal infant development. PIP aims to achieve this by targeting the mother's view of her infant, which may be affected by her own experiences, and linking them to her current relationship to her child, in order to improve the parent‐infant relationship directly.
