The pediatric extended examination at three: a system for diagnostic clarification of problematic three-year-olds
Insights
The Pediatric Extended Examination at Three (PEET) is a valid tool for identifying learning, attention, and behavior issues in preschoolers. This neurodevelopmental assessment helps pediatricians address parental concerns early.
Area of Science:
- Pediatric Neurodevelopmental Assessment
- Child Psychology
- Developmental Pediatrics
Background:
- Early identification of learning, attention, and behavior problems in young children is crucial.
- Existing assessment tools may require further validation for specific age groups.
- Parental concerns regarding child development necessitate reliable screening instruments.
Purpose of the Study:
- To establish normative performance standards for the Pediatric Extended Examination at Three (PEET) in a preschool population.
- To demonstrate the concurrent validity of the PEET by comparing its results with the McCarthy Scales of Children's Abilities.
- To evaluate the PEET's utility in identifying developmental concerns in children presenting with behavioral and developmental issues.
Main Methods:
- The PEET was administered to 201 preschool children in the Boston area to establish performance standards.
- Concurrent validity was assessed by correlating PEET results with the McCarthy Scales of Children's Abilities.
- PEET performance of 59 clinic-referred children with developmental concerns was compared to the community sample.
Main Results:
- Statistically significant agreement was found between PEET identified weaknesses and related McCarthy Scales indices.
- Children referred to a hospital clinic demonstrated significantly poorer performance on the PEET compared to the community sample.
- A distinct pattern of concerns emerged in the clinic-referred group, suggesting specific therapeutic implications.
Conclusions:
- The Pediatric Extended Examination at Three (PEET) is a valid and useful neurodevelopmental assessment instrument for 3- to 4-year-old children.
- The PEET effectively aids pediatricians in clarifying parental concerns about learning, attention, and behavior.
- The study supports the PEET's role in early detection and intervention for developmental challenges.
Abstract:
The Pediatric Extended Examination at Three (PEET) is a neurodevelopmental assessment system designed to aid in the early detection and clarification of problems with learning, attention, and behavior in 3- to 4-year-old children. In this study the PEET was administered to 201 preschool children in the Boston area to ascertain standards of performance on this instrument and to demonstrate concurrent validity with the McCarthy Scales of Children's Abilities. When children with specific weaknesses on the PEET were analyzed with regard to their McCarthy scores on related indices, statistically significant agreement was documented in all areas. Data from the PEET administered to 59 children in a hospital clinic for behavioral and developmental concerns, was compared to results from the Boston area community sample. Performance on the PEET of the former group was significantly poorer, and a pattern of concerns emerged with specific therapeutic implications. Based on the two components of this study, the PEET was shown to be a valid and useful instrument which can help pediatricians clarify parental concerns about their preschool children.
