Infant-Parent Psychotherapy

Infant-Parent Psychotherapy (IPP) is a therapeutic intervention for mother–infant pairs who may be at risk of an insecure attachment. Practitioners with a qualification in psychology or social work meet with individual families on a weekly basis for a period of 26 to 52 weeks. The practitioner also engages jointly with the mother and infant to model sensitive caregiving behaviour and suggest positive explanations for the child’s behaviour.

Model description

Infant-Parent Psychotherapy is one of three variations of the Lieberman model of child-parent psychotherapy for families with a 12-month infant who may be at risk of an insecure attachment. This risk may be due to difficulties with the parent–child relationship stemming from the parent’s own attachment history, complexities in the family’s life, including parental mental health problems, or specific risks associated with child abuse and neglect.

Mothers identified as being depressed, anxious, traumatised, or at risk of maltreating their child attend weekly sessions with their infant for a period of 12 months or longer. The sessions are delivered by practitioners with a master’s (or higher) qualification in psychology or social work.

During each session, the practitioner helps the mother reflect on her childhood experiences and differentiate them from her current relationship with her child through empathic, non-didactic support. The practitioner also engages jointly with the mother and infant, so that they can model sensitive responding and suggest positive explanations for the child’s behaviour. As the therapeutic relationship develops, the mother learns to appropriately interpret her infant’s behaviours and dissociate any negative attributions of her child from her own history of being parented.

Age of child

0 to 2 years old

Target population

Families with an infant at risk of an insecure attachment because of the parents’ attachment history, complex family circumstances, or specific child maltreatment risks.

Disclaimer: The information in this section is as offered/supported by the intervention provider.

Why?

Science-based assumption

Attachment security lays the foundation for children to develop positive expectations about themselves, and positive and sensitive parent–infant interactions support the development of a secure attachment relationship.

Science-based assumption

Sensitive parenting behaviours are supported by positive representations of the child. Negative parental representations of the child places the attachment relationship at risk.

Who?

Science-based assumption

Parents experiencing multiple hardships and/or an insecure attachment relationship in their own childhood are less likely to develop positive representations of their child.

How?

Intervention

Parents receive therapeutic support to improve their ability to form positive representations of their child

Parents learn how to respond more sensitively to their child’s needs and created a nurturing and predictable caregiving environment.

What?

Short-term

Parents develop positive representations of their infant

Parents are less likely to negatively attribute their child behaviour

Parents become more sensitive to their child’s needs.

Medium-term

Improved parent–infant interaction

Reduced risk of an insecure attachment relationship.

Long-term

Child develops positive expectations of themselves and others

Children are at less risk of mental health problems

Children are a less risk of child maltreatment.

Who is eligible?

Families with an infant at risk of an insecure attachment because of the parents’ attachment history, complex family circumstances, or specific child maltreatment risks.

How is it delivered?

IPP is delivered in 32 sessions of approximately 1 to 1.5 hours’ duration each by a single practitioner over the course of a year.

What happens during the intervention?

  • During each session, the practitioner uses empathic, non-didactic support to help the mother reflect on her childhood experiences and differentiate them from her current relationship with her toddler
  • The practitioner also engages jointly with the mother and infant, so that they can model sensitive responding and suggest positive explanations for the child’s behaviour
  • As the therapeutic relationship develops, the mother learns to appropriately interpret her infant’s behaviours and dissociate any negative attributions of her child from her own history of being parented.

Who can deliver it?

An IPP therapist with a master’s qualification or higher in counselling, psychology or social work.

What are the training requirements?

Practitioners receive 92 hours of IPP training . Booster training is recommended.

How are the practitioners supervised?

Practitioners are supervised by one host-agency supervisor, with 92 hours of intervention training, who provides clinical skills and case-management supervision.

What are the systems for maintaining fidelity?

  • Training manual
  • Booster sessions
  • Supervision.

Is there a licensing requirement?

Infant-Parent Psychotherapy’s (IPP) most rigorous evidence comes from a single RCT conducted in the United States consistent with Foundations’ Level 3 evidence strength criteria. Additional positive child impacts observed in a study consistent with Foundations’ Level 2+ evidence strength criteria qualify the intervention for a Level 3+ rating.

The studies observed statistically significant increases in infant’s attachment security in comparison to children whose mothers did not receive the treatment.
