Introduction: Developmental Coordination Disorder (DCD) is characterized by motor skill delays or difficulties in coordination that interfere with daily activities. DCD affects 5-6% of school-aged children, with higher prevalence in boys. It frequently co-occurs with Attention-Deficit/Hyperactivity Disorder (ADHD), with comorbidity rates of approximately 50%. Purpose: Examine correlations between ADHD symptoms, attentional and executive abilities, and DCD indicators in children evaluated within an interdisciplinary protocol for inattention and hyperactivity. Method: Fifty-four children aged 6-15 years (M = 9.9; SD = 2.9) were assessed using the BPA for attention, the Five Digits Test for executive functioning, and the WASI for intelligence. ADHD symptoms were measured with a DSM-5-based inventory, and the Developmental Coordination Disorder Questionnaire (DCDQ) was applied to identify DCD. Data were analyzed using Spearman correlation tests in Jamovi. Results: Significant negative correlations were found between DCD symptoms and Inhibition (ρ = -0.495; p = 0.019), indicating that greater motor difficulties were associated with poorer inhibitory control. A significant negative correlation also emerged between DCD and total ADHD symptoms (ρ = -0.326; p = 0.020), suggesting that more severe motor problems were linked to higher ADHD symptomatology. Positive but non-significant trends were observed with BPA-General (ρ = 0.279; p = 0.071) and BPA-Alternating Attention (ρ = 0.271; p = 0.079). No significant associations were detected with total IQ (ρ = 0.142; p = 0.319) or cognitive flexibility (ρ = -0.258; p = 0.247). Conclusions: Findings highlight that DCD symptoms are associated with deficits in inhibitory control and greater ADHD severity, reinforcing the overlap between motor and self-regulation difficulties. Motor deficits may selectively affect executive functions, particularly inhibition, and potentially extend to attentional processes. These results underscore the importance of integrated motor and cognitive assessments and interventions addressing the co-occurrence of DCD and ADHD in clinical and educational contexts.
