Parent-Child Interaction Therapy: A Meta-analysis

Area of Science:

• Child Psychology
• Behavioral Therapy
• Family Interventions

Background:

• Parent-Child Interaction Therapy (PCIT) is a recognized intervention for reducing externalizing behaviors in children.
• Modifications to PCIT are common, but their impact on treatment effectiveness remains unclear.

Purpose of the Study:

• To systematically review and meta-analyze the effects of PCIT on child externalizing behaviors.
• To examine how modifications, study design, and bias influence PCIT's effectiveness.

Main Methods:

• Searched major academic databases (PubMed, PsycINFO, ERIC, etc.) for relevant studies.
• Included randomized controlled trials and quasi-experimental trials in the meta-analysis.
• Analyzed outcomes including child behavior, parent stress, and parent-child interactions.

Main Results:

• PCIT significantly reduced child externalizing behaviors (SMD: -0.87) compared to controls.
• PCIT requiring skill mastery demonstrated superior reductions in externalizing behaviors (SMD: -1.09) versus non-mastery (SMD: -0.51).
• PCIT also decreased parent stress and improved child compliance.

Conclusions:

• PCIT demonstrates robust positive outcomes in parent-reported and observed measures.
• PCIT appears effective across various settings and populations, even with modifications.
