Insights
A structured interview effectively assigned International Classification of Functioning, Disability, and Health (ICF) codes for children with special health care needs. This method showed high rater agreement, proving more reliable than standardized assessments.
Area of Science:
- Pediatric Health Services Research
- Rehabilitation Medicine
- Disability Studies
Background:
- Children with special health care needs (CSHCN) require comprehensive functional assessments.
- The International Classification of Functioning, Disability, and Health (ICF) provides a standardized framework for describing health and functioning.
- Accurate ICF coding is crucial for service planning and research in CSHCN.
Purpose of the Study:
- To evaluate the reliability of assigning ICF codes and performance qualifiers by two rater teams.
- To assess the effectiveness of a developmentally structured interview for coding CSHCN.
- To compare the interview's reliability against standardized functional assessments.
Main Methods:
- Forty children (11 months to 12 years 10 months) with diverse health conditions participated.
- A structured interview with open-ended questions was administered and scored using developmental guidelines.
- Two independent raters assigned ICF codes and performance qualifiers, with inter-rater reliability measured by Cohen's kappa statistic.
Main Results:
- High inter-rater agreement was achieved for most ICF codes (39/39 by Team I, 38/39 by Team II).
- Good to excellent agreement was observed for performance qualifiers (5/5 by Team I, 10/14 by Team II).
- The structured interview demonstrated strong reliability in coding CSHCN.
Conclusions:
- A developmentally structured interview is a viable clinical tool for assigning ICF codes to CSHCN.
- This interview method yielded higher agreement rates compared to traditional standardized functional assessments.
- Modifications to ICF performance qualifier guidelines are recommended for pediatric application.
Purpose:
The purpose of this study was to determine if two teams of raters could reliably assign codes and performance qualifiers from the Activities and Participation component of the International Classification of Functioning, Disability, and Health (ICF) to children with special health care needs based on the results of a developmentally structured interview.
Method:
Children (N = 40), ages 11 months to 12 years 10 months, with a range of health conditions, were evaluated using a structured interview consisting of open-ended questions and scored using developmental guidelines. For each child, two raters made a binary decision indicating whether codes represented an area of need or no need for that child. Raters assigned a performance qualifier, based on the ICF guidelines, to each code designated as an area of need. Cohen's kappa statistic was used as the measure of inter-rater reliability.
Results:
Team I reached good to excellent agreement on 39/39 codes and Team II on 38/39 codes. Team I reached good to excellent agreement on 5/5 qualifiers and Team II on 10/14 qualifiers.
Conclusions:
A developmentally structured interview was an effective clinical tool for assigning ICF codes to children with special health care needs. The interview resulted in higher rates of agreement than did results from standardized functional assessments. Guidelines for assigning performance qualifiers must be modified for use with children.
