For example, some have found significant differences between children with divorced and continuously married parents even after controlling for personality traits such as depression and antisocial behavior in parents.59 Others have found higher rates of problems among children with single parents, using statistical methods that adjust for unmeasured variables that, in principle, should include parents» personality traits as well as many genetic influences.60 And a few studies have found that the link between parental divorce and children's problems is similar for adopted and biological children — a finding that can not be explained by genetic transmission.61 Another study, based on a large sample of twins, found that growing up in a single - parent family predicted depression in adulthood even with genetic resemblance controlled statistically.62 Although some degree of selection still may be operating, the weight of the evidence strongly suggests that growing up without two biological parents in the home increases children's risk of a variety of cognitive, emotional, and social problems.
