Abstract

OBJECTIVE. The aim of this study was to evaluate interrater and intrarater reliability for the Assisting Hand Assessment.

METHOD. For interrater reliability, two designs were used: 2 occupational therapists rated the same 18 children, and 20 occupational therapists rated the same 8 children. For intrarater reliability, 20 raters each rated one child twice. Both English and Swedish versions of the instrument were used. Intraclass correlation coefficients (ICCs) and standard error of measurement (SEM) were calculated.

RESULTS. ICCs for the sum score for the interrater were 0.98 (two raters) and 0.97 (20 raters) and for the intrarater 0.99. SEM was 1.5 for interrater and 1.2 for the intrarater study, which gave an error interval of ± 3 raw scores for interrater and ± 2.4 raw scores for intrarater.

CONCLUSION. This study shows excellent interrater and intrarater reliability for sum scores.
