Identifying Children with Developmental Coordination Disorder via Parental Questionnaires. Spanish Reference Norms...

Area of Science:

• Neurodevelopmental Disorders
• Pediatric Motor Performance
• Psychometrics

Background:

• Developmental Coordination Disorder (DCD) is a common neurodevelopmental disorder impacting school-aged children's psychosocial and physical health.
• Accurate identification of DCD is crucial for timely and effective interventions.
• Existing assessment tools require culturally adapted norms for diverse populations.

Purpose of the Study:

• To develop Spanish adjusted reference norms for the DCDDaily-Q (DCDDaily-Q-ES).
• To evaluate the correlation and agreement between the DCDDaily-Q-ES and the DCDQ-ES for DCD assessment.
• To provide clinically relevant percentiles and cutoff scores for the Spanish version.

Main Methods:

• A representative sample of 356 Spanish children aged 5–10 years participated.
• Clinically relevant percentiles were calculated for the DCDDaily-Q-ES.
• Pearson's correlation and intraclass correlation coefficients (ICC) were used to assess correlation and agreement between DCDDaily-Q-ES and DCDQ-ES.

Main Results:

• A moderate and significant correlation (r = 0.406) and agreement (ICC = 0.381) were found between DCDDaily-Q-ES and DCDQ-ES (p < 0.001).
• Age-related differences in daily participation and performance were observed.
• No significant gender-based differences were found in motor performance.

Conclusions:

• The study successfully developed Spanish age-adjusted norms for the DCDDaily-Q-ES, enhancing DCD identification in Spanish-speaking children.
• The findings support the use of DCDDaily-Q-ES as a valid tool, showing good correlation and agreement with the DCDQ-ES.
• These results have practical implications for clinical practice, research, and intervention strategies for DCD in Spain.
