Evaluation of a screening instrument for developmental coordination disorder.
OBJECTIVE
To validate the Children's Self-Perceptions of Adequacy in, and Predilection for Physical Activity (CSAPPA) scale as a proxy for the BOTMP test in diagnosing DCD.


METHODS
A sample of 209 children (M = 121; F = 87) consented to the BOTMP test, CSAPPA scale, Participation Questionnaire, Léger 20-meter Shuttle Run, and body fat using bioelectric impedance. Receiver Operating Characteristic (ROC) curve analysis and Kappa statistic were used to validate the CSAPPA scale as a predictor for significant clumsiness on the BOTMP test.


RESULTS
Prevalence of DCD was.09 +/-.03 of both males and females, all previously undiagnosed. A positive cutoff of < 47 and < 53 for DCD on the CSAPPA scale was identified in male and females, respectively. Both gender cut-offs demonstrated significant agreement (p <.01) with a positive BOTMP test. Males' results indicated a sensitivity and specificity values of.90 (CI =.18) and.89 (CI =.22). Likewise, the female subject cutoff demonstrated high sensitivity [.88 (CI =.05)] and specificity [75 (CI =.09)]. Gender specific analysis of variance (ANOVA) indicated that students identified as clumsy were not significantly different in age or height from their peers, but demonstrated significantly (p <.01) lower self-efficacy, aerobic fitness, and had significantly (p <.01) higher relative body fat. These results held true for both genders.


CONCLUSIONS
These findings are consistent with the characteristics of children with DCD. These results suggest that the CSAPPA scale is a promising instrument for use in screening children for developmental coordination disorder.
