Sensitive people are more affected by their experiences and sensitivity has a genetic basis. We tested whether genetic sensitivity predicts the response to a relationship education programme. We found that individuals with high genetic sensitivity improved more strongly regarding several aspects of relationship quality even two years after attending a relationship programme.
Intervention research has recently started to focus on genetic differences in order to explain why interventions work better for some than others. However, establishing the reliability of such genetic research is fundamental.
Our study investigated the heritability of sensitivity.
Results showed that 47 percent of the differences in sensitivity between individuals are genetically determined, whereas the remaining 53 percent are accounted for by environmental factors.
Environmental Sensitivity is seen in both animals and humans, suggesting that is has a strong biological foundation.
