AIM: To investigate the interrater and test-retest reliability of the Assisting
Hand Assessment in adolescents (Ad-AHA) with cerebral palsy (CP) and to evaluate
the alternate-form reliability of different test activities.
METHOD: Participants
were 112 adolescents with unilateral CP (60 males, 52 females; mean age 14y 5mo
[standard deviation {SD} 2y 8mo], Manual Ability Classification System levels
I-III). Reliability was evaluated using intraclass correlation coefficients
(ICC), smallest detectable change (SDC), and Bland-Altman plots. RESULTS: ICCs
for interrater (n=38) and test-retest reliability (n=31) were excellent: 0.97
(95% CI 0.94-0.98) and 0.99 (95% CI 0.98-0.99) respectively. The alternate-form
reliability of different test activities was excellent for children (age 10-12y,
n=30) performing the School-Kids AHA and Ad-AHA Board Game 0.99 (95% CI
0.98-0.99) and for adolescents (age 13-18y) performing the Ad-AHA Board Game
compared to the Ad-AHA Present (n=28) 0.99 (95% CI 0.95-0.98), or the Ad-AHA
Sandwich (n=29) 0.99 (95% CI 0.98-0.99) tasks. SDC for test-retest was 4.5
AHA-units. INTERPRETATION: Ad-AHA scores are consistent across different raters
and occasions. The good alternate-form reliability indicates that the different
test activities can be used interchangeably in adolescents with unilateral CP.
Differences greater than or equal to 5 AHA-units can be considered a change
beyond measurement error.
The use of logit based AHA-units makes change
comparable for persons at different ability levels.
