Assessment of the psychometric properties of the Graded Care Profile version 2 (GCP2) tool for measuring child neglect

Child neglect is highly prevalent, with extensive effects on children's development and often long‐lasting consequences. It is a complex issue, and the identification and assessment of neglect presents particular difficulties for professionals. The Graded Care Profile (GCP) is a tool that can help practitioners to assess neglect, but the updated version of this tool (GCP2) requires psychometric testing. We sought to test the GCP2 with qualified social work practitioners in the United Kingdom. Interrater reliability was assessed by comparing GCP2 scores between 3 pairs of practitioners following assessments of 30 children. Concurrent validity was assessed by comparing GCP2 scores to scores obtained using 2 other validated measures with 15 children. Professionals were surveyed concerning face validity. There was a substantial level of interrater agreement for 2 domains and a moderate level of agreement for the other 2 domains. There were strong correlations between the GCP2 and the other tools across all domains, and face validity results were positive. In conclusion, although this was a small sample, our findings provide preliminary evidence that the GCP2 has adequate psychometric properties pending further rigorous psychometric testing. It is thus likely to be a useful tool in aiding professionals in the assessment of child neglect.
