Relations
between Reading Achievement and Antisocial Behavior in Young British
Twins: Tests of Environmental and Genetic Hypotheses
Elevated rates of antisocial behavior have been
found among children who are poor readers. However, it has not been
clear whether antisocial behavior interferes with learning to read,
whether poor reading skills raise risks for antisocial behavior,
or whether these different kinds of problems are related in other
ways. Using a national longitudinal sample of British twins, Trzesniewski
et al. (2006) tested associations between reading achievement at
age 7 and antisocial behavior (measured in terms of CBCL and TRF
Externalizing scores) at ages 5 and 7. Genetic factors were not
found to explain the associations between poor reading achievement
and antisocial behavior. Instead, among boys, the association between
reading achievement and antisocial behavior was accounted for mainly
by environmental risk factors that are common to both kinds of problems.
Several risk factors, such as low SES, unstimulating home environments,
and child neglect were significant predictors of both poor reading
achievement and antisocial behavior. Furthermore, tests of causal
models revealed reciprocal relations between antisocial behavior
and poor reading achievement, such that the presence of either one
could raise the risk for the other. However, among girls, the associations
were generally weaker and indicated that antisocial behavior was
a risk factor for poor reading achievement but not vice versa. By
contrast, associations between attention problems and poor reading
achievement were accounted for mainly by genetic factors.
