The Child-Focused Injury Risk Screening Tool (ChildFIRST) is a process-based assessment including 10 movement skills with 4 associated evaluation criteria. The ChildFIRST has been validated by a group of experts to evaluate movement competence and injury risk in 8-12-year-olds. The purpose of this study is to evaluate the reliability of the ChildFIRST. Twelve college-aged subjects participants attended a 1-hr training session. To evaluate inter-rater reliability, the participants rated 6 videos per movement, 60 videos in total. To evaluate intra-rater reliability, the participants returned after 7 days to rate the same videos. Movement skill inter-rater reliability ranged from -0.306 to 9.380 ICC, intra-rater reliability ranged from -0.386 to 0.881 ICC. Evaluation criteria inter-rater reliability ranged from -0.04 to 0.835 Ka and 52-100% agreement, intra-rater reliability ranged from -0.328 to 0.303 Cohen's K and 45.8-98.6% agreement. The ChildFIRST demonstrates moderate-to-excellent inter-rater reliability for 9 of 10 movement skills, while intra-rater reliability and overall evaluation criteria reliability range from good to poor.
