Children with Attention-Deficit Hyperactivity Disorder (ADHD) by Family Structure and Religious Practice
The 2001 cycle of the National Health Interview Survey (NHIS) showed that children in intact families that worshipped were least likely to have been diagnosed with Attention-Deficit Hyperactivity Disorder (ADHD). 
Family Structure: According to the 2001 cycle of the National Health Interview Survey, 4.7% of children in intact married families, 8.0% of children raised in remarried stepfamilies, and 8.6% of children living with a cohabiting parent had been told by a doctor that they had ADHD. Children living in single-parent families were most likely to have been diagnosed with ADHD (9.1%).
Religious Practice: The 2001 cycle of the National Health Interview Survey showed that fewer children from families who worshipped had been diagnosed with ADHD (5.2%) than children whose families did not worship (7.1%).
Family Structure and Religious Practice Combined: Children in intact families that worshipped were least likely to have been diagnosed with ADHD (3.7%), followed by children in intact non-worshipping families (4.8%) and non-intact worshipping families (6.9%). Children in non-intact non-worshipping families were most likely to have been told by a doctor that they have ADHD (8.6%)—more than double that of children in intact worshipping families.
Related Insights from Other Studies: A robust collection of research shows that family structure can significantly impact the mental health of children. Ann-Margret Rydell found that single parenthood and step-parenthood was associated with high levels of ADHD symptoms, and that family conflict had a strong additive effect on the level of ADHD symptoms in children (beyond the effects of demographic factors).  Using the National Survey of Children’s Health, Matthew D. Bramlett and Stephen J. Blumberg found that more than two times as many children raised in blended step-families, blended adoptive families, and grandparent families were ever told their child has ADD/ ADHD than children raised in two-parent families. These studies reiterate that children tend to be healthier in two-parent biological families.
 A worshipping family has attended at least one worship service in the past two weeks.
