Abstract

OBJECTIVE:

To assess whether the Movement ABC can be used to monitor individual change in motor performance.

DESIGN:

Motor-impaired children were tested three times in succession with the Movement ABC without any intervention.

SETTING:

Two schools for special education and one school for children who are chronically ill.

SUBJECTS:

Three girls and 20 boys aged 6-8 years.

MAIN OUTCOME MEASURES:

Scores were measured per item (0 --> 5), added to cluster scores (0 --> 10 or 15), added to form the total scores (0 --> 40). Mean scores, standard errors of measurement (SEMs) and least detectable differences (LDDs) were calculated per item, per cluster and for the total scores. A repeated measures analysis of variance was performed to test for the effects of time.

RESULTS:

The total scores improved significantly from the first session (mean: 15.4 points) to the second (mean: 13.3), but not from the second to the third (mean: 13.2). Average item scores ranged from 0.6 to 2.7 points with SEMs of 0.79 --> 1.54 and LDDs of 2.20 --> 4.27. Average cluster scores ranged from 3.4 to 5.3 with SEMs of 1.51 --> 1.84 and LDDs of 4.18 --> 5.11. The SEM of the total scores equalled 3.13 with an LDD of 8.68.

CONCLUSIONS:

The total score of the Movement ABC is sufficiently sensitive to monitor individual change; the cluster scores have moderate sensitivity and individual items are inappropriate to monitor individual change. The significant effect of time is interpreted as an effect of learning.
