Single mothers may have a calmer, more conflict-free relationship with their teens than married mothers do, according to a developmental psychologist at the University of Rochester.

In a comparison of divorced and married families from the same school district, Judith Smetana found that "married mothers talked about fighting more frequently with their teens, and the children of married mothers reported more serious squabbles."Smetana believes that teens with single mothers often have more independence and responsibility than other teens, and so they may not feel the same need to rebel against parental authority.
