Child-Parent Psychotherapy

Child-Parent Psychotherapy (CPP) is a therapeutic intervention for parents with a child between 3 and 5 years old who may have experienced trauma or abuse (including domestic abuse). 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. Parents receive support for their symptoms of trauma alongside advice aimed at supporting the needs of the child.

Model description

CPP is one of three variations of the Lieberman model of child-parent psychotherapy for families with a child aged between 3 and 5 years who has experienced trauma or abuse. The intervention aims to improve children’s representations of their relationship with their parent and reduce parent and child symptoms of mental health.

CPP is delivered by a master’s-level or higher clinical psychologist or social worker to parents and children individually through 32 weekly sessions over the course of 26 to 52 weeks. Typically, the parent and child attend sessions at an outpatient health setting, although the intervention can also be delivered in the home or a women’s shelter.

A primary aim of CPP is to stop the intergenerational transmission of family violence by helping the custodial parent to understand how it is negatively impacting the child. Therapists accomplish this by forming a strong therapeutic alliance at the start of the intervention, which then creates the context in which parents are better able to fully attend to their child’s needs.

During each session, the practitioner uses empathic, non-didactic support to help the parent reflect on their childhood experiences and differentiate them from their current relationship with her child. Parent sessions are interspersed with sessions involving the child, where the parent, therapist, and child jointly engage in structured play aimed at eliciting trauma-related feelings and behaviours. This allows the therapist to help the parent and child develop a joint narrative around the traumatic events and bring them to their resolution. Parents also receive support in appropriate discipline and an increased awareness of their child’s moods and emotional states.

Age of child

3 to 5 years old

Target population

Disadvantaged families with concerns about their child’s behaviour.

Why?

Science-based assumption

Experiences of maltreatment, trauma and ongoing family stress during the early years increases the risk of poor outcomes in childhood and adolescence.

Science-based assumption

Sensitive parenting reduces the risk of child maltreatment and increases children’s resilience to family stress and traumatic events in early childhood.

Who?

Science-based assumption

Parents experiencing high levels of stress or unresolved trauma are more likely to have difficulty responding sensitively to their child’s needs.

How?

Intervention

Parents are supported to manage their stress

Parents are supported to respond sensitively to their child’s needs.

Who is eligible?

How is it delivered?

CPP is delivered in 32 sessions of approximately 1 to 1.5 hours’ duration each by a single practitioner with 92 hours of intervention training.

What happens during the intervention?

  • Mothers and their child attend weekly sessions for a period of 12 months or longer.
  • 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 child.
  • Parent sessions are interspersed with sessions involving the child, where the mother, therapist and child jointly engage in structured play aimed at eliciting trauma-related feelings and behaviours. This allows the therapist to help the mother and child develop a joint narrative around the traumatic events and bring them to their resolution.
  • Mothers also receive support in appropriate discipline and an increased awareness of their child’s moods and emotional states.

Who can deliver it?

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

What are the training requirements?

Practitioners receive 92 hours of CPP training (seven days’ face-to-face training with 36 hours of phone consultation). Booster training is recommended.

CPP’s most rigorous evidence comes from one RCT conducted in the United States consistent with Foundations’ Level 3 evidence strength criteria. The study identified statistically significant reductions in children’s symptoms of trauma, as well as improved child behaviour which persisted six months post treatment. The intervention is also supported by one RCT that fulfils Foundations’ Level 2+ evidence strength criteria.

CPP can be described as evidence-based: it has evidence from at least one rigorously conducted RCT or QED demonstrating a statistically significant positive impact on at least one child outcome, as well as at least one more RCT or QED.

Interpretation

2.29-point improvement on the semi-structured interview for diagnostic classification immediately after intervention. This means we would expect the average participant in the comparison group who did not receive the intervention (i.e., someone for whom 50% of their peers have better outcomes and 50% have worse outcomes), to improve to the point where they would have better outcomes than 74% and worse outcomes than 26% of their peers, if they had received the intervention.

This means we would expect the average participant in the comparison group who did not receive the intervention (i.e., someone for whom 50% of their peers have better outcomes and 50% have worse outcomes), to improve to the point where they would have better outcomes than 59% and worse outcomes than 41% of their peers, if they had received the intervention.
