Abstract Aim: To examine internal consistency, test-retest reproducibility, and parent-child concordance of the Dimensions of Mastery Questionnaire 17.0 (DMQ) in school-aged children with congenital hemiplegia. Method: Forty-two children (8.24 +/- 2.38 years, Manual Ability Classification System (MACS) I = 23, MACS II = 19) and their parents completed the DMQ, and a subset on two occasions 2-30 days apart (n = 27). Cronbach's alpha (alpha), intraclass correlation coefficients (ICCs), standard error of measurement (SEM), and 95% limits of agreement were calculated. Results: Internal consistency for child self-report was variable (alpha = 0.57-0.90). Cronbach's alphas for parent proxy report were good (alpha = 0.69-0.86). Test-retest reproducibility for instrumental aspect (ICC = 0.86) and total motivation (ICC = 0.84) were excellent with subscales ranging from 0.70 to 0.91. The SEM for total motivation was 0.23 points. Parent-child concordance was poor across all scores (ICC=-0.04 to 0.42) with a large SEM (0.50-0.91). Interpretation: The DMQ parent report has good test-retest reproducibility for subscales, instrumental, and total motivation scores in school-aged children with congenital hemiplegia. Parent-child concordance was low highlighting differences in individual and contextual perspectives.

Aim:
To examine internal consistency, test–retest reproducibility, and parent–child concordance of the Dimensions of Mastery Questionnaire 17.0 (DMQ) in school-aged children with congenital hemiplegia.

Method:
Forty-two children (8.24 ± 2.38 years, Manual Ability Classification System (MACS) I = 23, MACS II = 19) and their parents completed the DMQ, and a subset on two occasions 2–30 days apart (n = 27). Cronbach's alpha (α), intraclass correlation coefficients (ICCs), standard error of measurement (SEM), and 95% limits of agreement were calculated.

Results:
Internal consistency for child self-report was variable (α = 0.57–0.90). Cronbach's alphas for parent proxy report were good (α = 0.69–0.86). Test–retest reproducibility for instrumental aspect (ICC = 0.86) and total motivation (ICC = 0.84) were excellent with subscales ranging from 0.70 to 0.91. The SEM for total motivation was 0.23 points. Parent–child concordance was poor across all scores (ICC = −0.04 to 0.42) with a large SEM (0.50–0.91).

Interpretation:
The DMQ parent report has good test–retest reproducibility for subscales, instrumental, and total motivation scores in school-aged children with congenital hemiplegia. Parent–child concordance was low highlighting differences in individual and contextual perspectives.
