Objective: To develop the DCDDaily, an instrument for objective and standardized
clinical assessment of capacity in activities of daily living (ADL) in children with developmental coordination disorder (DCD), and to investigate its usability,
reliability, and validity. Subjects: Five to eight-year-old children with and
without DCD. Main measures: The DCDDaily was developed based on thorough review
of the literature and extensive expert involvement. To investigate the usability
(assessment time and feasibility), reliability (internal consistency and
repeatability), and validity (concurrent and discriminant validity) of the
DCDDaily, children were assessed with the DCDDaily and the Movement Assessment
Battery for Children-2 Test, and their parents filled in the Movement Assessment
Battery for Children-2 Checklist and Developmental Coordination Disorder
Questionnaire. Results: 459 children were assessed (DCD group, n = 55; normative
reference group, n = 404). Assessment was possible within 30 minutes and in any
clinical setting. For internal consistency, Cronbach's alpha = 0.83. Intraclass
correlation = 0.87 for test-retest reliability and 0.89 for inter-rater
reliability. Concurrent correlations with Movement Assessment Battery for
Children-2 Test and questionnaires were rho = -0.494, 0.239, and -0.284, p <
0.001. Discriminant validity measures showed significantly worse performance in
the DCD group than in the control group (mean (SD) score 33 (5.6) versus 26
(4.3), p < 0.001). The area under curve characteristic
= 0.872, sensitivity and
specificity were 80%. Conclusions: The DCDDaily is a valid and reliable
instrument for clinical assessment of capacity in ADL, that is feasible for use
in clinical practice.
