Parent-directed, intensive early intervention for children with pervasive developmental disorder

Area of Science:

• Developmental Psychology
• Pediatric Behavioral Health
• Clinical Psychology

Background:

• Pervasive Developmental Disorder (PDD) requires effective early intervention strategies.
• Parent-directed models offer a scalable approach to intensive early intervention.
• The UCLA treatment model is a recognized intervention for early childhood developmental disorders.

Purpose of the Study:

• To evaluate the efficacy of parent-directed early intervention for children with PDD.
• To assess skill acquisition, long-term outcomes, treatment quality, and parental satisfaction.
• To explore the feasibility of implementing intensive home-based interventions through parent recruitment.

Main Methods:

• Six young boys with PDD (35-45 months) participated.
• Parents recruited and trained paraprofessional therapists in the UCLA model.
• Intervention involved workshops and ongoing consultations over 2-3 years.

Main Results:

• Five out of six children demonstrated rapid initial skill acquisition.
• Only two children showed clear improvement on standardized tests at follow-up.
• Therapists generally adhered to treatment procedures but with variable consistency compared to clinic settings.
• Parents reported high satisfaction with the intervention.

Conclusions:

• Parent-directed early intervention can lead to initial skill development in children with PDD.
• Long-term outcomes may be variable, necessitating careful monitoring and assessment.
• High parent satisfaction suggests potential for home-based models, but treatment fidelity requires attention.
• Multimodal assessment is crucial for understanding the impact of parent-directed treatments.
