Background and Aims: Previous studies have shown that parental socioeconomic status affects directly participating of children in physical activity and consequently improve motor competencies. Nevertheless, this issue has been less studied in children with ADHD. Therefore, the present study was designed to investigate the associations between parental socioeconomic status and motor competence with considering physical activity as a mediator.

Methods: The present study used a descriptive-correlational approach using structural equation modelling. The statistical population of this study included 86 male students diagnosed for ADHD (mean age of 8.36±1.07) attended in special school in Tehran. Short-Form Bruininks-Oseretsky Battery, Parental Socioeconomic Status Scale, and Physical Activity Questionnaire for Children were use for data collection. Pearson correlation test and structural equation modelling were used for investigating the relationships between the research variables.

Results: BMI of the participants was 16.9, placing the BMI-for-age at the 70-percentile indicating that they have healthy weight. Children in this study had lower-average motor competence (e.g., balance, upper limb coordination, and strength), their parents were mostly at medium level of socioeconomic status, and physical activity level of children was lower than average (M=2.23). In addition, parental socioeconomic status positively affected motor competence (T=6.862) and physical activity (T=5.151) as well as physical activity positively impacted motor competence (T=5.593).

Conclusion: Lower amount of physical activity in our sample make it necessary to find out appropriate factors and strategies to enhance it in children with ADHD. According to our findings, education and income of parents as well as participation of children with ADHD in physical activity may be critical concerns for their health.
