“…They were also more likely to share less with their twins and evoke less sensitivity from their parents during family interactions (DiLalla et al, 2009b). Similarly, those children with the DRD4-L allele and lower parental sensitivity were more likely to display conduct problems (DiLalla et al, 2011). Moreover, children with the risk allele for the 5HTT gene were more likely to display conduct problems, regardless of the level of parental sensitivity (DiLalla et al, 2011).…”

The Southern Illinois Twins and Siblings Study (SITSS): Description and Update

2012

This update on the Southern Illinois Twins and Siblings Study (SITSS) documents some of the follow-up studies that have been conducted and results that have been obtained from this sample. At the current time, 283 twin pairs, 8 triplet families, 98 non-twin sibling pairs, and 287 singletons have been enrolled in SITSS. Twins and triplets are tested as young as 1 year of age and then every year on their birthday through age 5 years. A variety of follow-up studies have been conducted for SITSS children through age 20. Results thus far have demonstrated significant genetic influences on social behaviors such as aggression, victimization, and attention toward facial expressions. Interesting interactions have been documented between the dopamine receptor D4 gene (DRD4) and the social environment (parental sensitivity or peer aggression) as they predict children's aggressive behaviors. In addition, increased difficulty with social interactions has been noted for twins versus singletons. Thus, this multi-trait, multi-method behavior genetic data set contributes to our understanding of the etiology of social behaviors in preschoolers and to predictors of similar behaviors through adolescence.
