The effect of family environment on the development of Attention Deficit-Hyperactivity Disorder (ADHD) is not known. We sought to characterize families with children with ADHD in order to better understand the contributions of family environment to the development of ADHD. We collected demographic data, parents’ and teachers’ rating scales, intellectual quotient, and the family environment scale (FES) for 53 children (aged 4-13), 29 with ADHD diagnosis and 24 controls. Statistical analysis indicated a family environment profile within the average range for both samples. There were significant differences between ADHD and controls for the measures of cohesion, intellectual activity orientation, and recreational activities orientation. Greater severity of the TDAH symptoms was related to less cohesion and more conflict. There seems to be no association between the quality of the family environment and the diagnosis of ADHD.
