Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Estimated DCD prevalence varies by study (1.8% to 6.9%) depending on definition, cut-off score, and population, with a male predominance ranging from 2:1 to 3:1. → Biotteau M 2019
q2 i? Longitudinal studies show DCD persists into adulthood, with reported persistence of 30–70% for individuals diagnosed as children. → Biotteau M 2019 (2)

The review reports prevalence estimates from population studies, citing Lingam et al's UK study of 6,990 children aged 7–8 years that found "a prevalence of 1.8%", rising to 4.9% (n=341) when probable DCD was included; other studies reported 6.9% or 4.3%. No effect sizes are printed.
"The estimated prevalence of DCD varies according to the studies (depending on the definition, cut-off score, and population studied). Lingam et al found a prevalence of 1.8% in their study among 6,990 children aged 7–8 years in the UK, but this figure rose to 4.9% (n=341)"

q2 · i? · review · r2
The review's abstract states longitudinal persistence figures: "DCD persistence of 30–70% in adulthood" for childhood-diagnosed individuals, with academic consequences. The review attributes this to longitudinal studies; no effect sizes are printed.
"Studies show DCD persistence of 30–70% in adulthood for individuals who were diagnosed with DCD as children, with direct consequences in the academic realm and even beyond."
Discussion¶
Related Claims¶
- Motor imagery training improves motor performance in DCD, with children showing the most severe initial motor deficits benefiting the most — related
- About half of all children with DCD experience difficulty learning to write, making dysgraphia assessment essential because handwriting difficulties do not resolve without intervention — related
- Process-oriented (bottom-up) therapies for DCD show weak or null effects, while task-oriented approaches are effective in improving motor performance — related
- Motor skill interventions for DCD improve motor, cognitive, and emotional outcomes, with dose (duration and frequency) influencing treatment effects and interventions of at least 9 weeks tending to be more effective — related
- Developmental dyscalculia persists into adulthood when untreated, affecting 5–7% of the general population — related
- Developmental writing disorders affect about 7–15% of school-aged children, with boys more affected than girls — related
