Insights
The Preschool Pediatric Symptom Checklist (PPSC) is a new tool for screening social/emotional issues in young children. It demonstrates reliability and accuracy comparable to existing screeners in pediatric primary care settings.
Area of Science:
- Child Psychology
- Pediatric Healthcare
- Psychometric Assessment
Background:
- Social/emotional development is crucial in early childhood.
- Existing screening tools may have limitations in primary care settings.
- There is a need for brief, reliable instruments for early identification of developmental concerns.
Purpose of the Study:
- To describe the development and initial validation of the Preschool Pediatric Symptom Checklist (PPSC).
- To establish the PPSC as a social/emotional screening instrument for children aged 18-60 months.
- To adapt the Pediatric Symptom Checklist model for preschool-aged children.
Main Methods:
- Expert review of existing instruments and literature for item generation.
- Scale construction and validation using factor analysis on data from 292 primary care and 354 referral clinic families.
- Independent replication sample of 171 families from primary care sites.
Main Results:
- Exploratory factor analysis identified four dimensions: Externalizing, Internalizing, Attention Problems, and Parenting Challenges.
- A bifactor model supported a strong general factor and total score use.
- The PPSC demonstrated strong internal and retest reliability.
- The PPSC effectively identified children with clinical scores on the Child Behavior Checklist and those with behavioral diagnoses.
- Sensitivity and specificity were comparable to the Ages & Stages Questionnaire: Social/Emotional.
- Results were consistent in an independent replication sample.
Conclusions:
- The Preschool Pediatric Symptom Checklist (PPSC) shows promise as a valid and reliable social/emotional screening tool.
- The PPSC is suitable for use in pediatric primary care settings for children aged 18-60 months.
- The PPSC offers a brief yet effective method for early identification of social/emotional difficulties.
Objective:
This article describes the development and initial validation of the Preschool Pediatric Symptom Checklist (PPSC), a social/emotional screening instrument for children 18 to 60 months of age. The PPSC was created as part of a comprehensive screening instrument designed for pediatric primary care and is modeled after the Pediatric Symptom Checklist.
Method:
Items for the PPSC were developed by a team of experts who reviewed existing assessment instruments and relevant research literature. Scale construction and initial validation (including factor analysis and tests of construct validity) were conducted with 292 families from pediatric primary care sites and 354 families from referral clinics. One hundred seventy-one additional families were recruited from primary care sites to obtain an independent replication sample.
Results:
Exploratory factor analysis revealed 4 dimensions of the PPSC: Externalizing, Internalizing, Attention Problems, and Parenting Challenges. These dimensions were incorporated into a bifactor model that displayed a strong general factor, thus supporting the use of a total score. The PPSC total score shows strong internal and retest reliability, and it identifies children who score in the clinical range of a longer, well-validated, and more comprehensive parent-report instrument (the Child Behavior Checklist), as well as children who are reported to have a range of behavioral diagnoses. Moreover, sensitivity and specificity with respect to these criteria were comparable to those of another well-accepted but longer screener, the Ages & Stages Questionnaire: Social/Emotional. Finally, results for the PPSC total scale remained consistent when replicated in an independent sample.
Conclusion:
The PPSC shows promise as a social/emotional screening instrument for use in pediatric primary care.
