Parent-Child Interaction Therapy in a Case of Global Developmental Delay and Leukoencephalopathy

Area of Science:

• Pediatric Psychology
• Developmental Pediatrics
• Behavioral Therapy

Background:

• Parent-child interaction therapy (PCIT) is an evidence-based treatment for children aged 2-7 with behavioral disorders.
• A 3-year-old girl with leukoencephalopathy, brainstem dysgenesis, global developmental delay, and later diagnosed muscular dystrophy presented with severe disruptive behaviors and self-injury.
• The child exhibited a developmental level of 18 months with limited language skills (12-18 months), poor motor coordination, and restricted fine motor abilities.

Observation:

• PCIT was initiated, emphasizing PRIDE skills (Praise, Reflection, Imitation, behavioral Description, Enjoyment), with a focus on behavioral description and labeled praise.
• Treatment modifications included non-verbal praise (e.g., high fives), sign language, and simplified one-step commands to enhance compliance.
• The patient exhibited rapid improvement in disruptive behaviors within weeks, noted by parents, daycare, and clinical observation.

Findings:

• The child's disruptive behaviors, including self-injury, significantly decreased.
• Her vocabulary more than doubled, and her self-expression abilities improved, enabling her to request items verbally and through pointing.
• Compliance with commands and overall communication skills showed marked enhancement.

Implications:

• This case suggests PCIT principles can be beneficial for children outside typical diagnostic criteria, including those with global developmental delay and complex medical conditions.
• Targeted PCIT interventions positively impacted language development and communication in a young child with significant developmental challenges.
• The findings support the adaptability and efficacy of PCIT in addressing behavioral and communication deficits in diverse pediatric populations.
