In this study, we sought to elucidate both stable and changing factors in the longitudinal structure of neuroticism using a behavioral genetic twin design. We tested whether this structure is best accounted for by a trait-state, a trait-only, or a state-only model. In line with classic views on personality, our results revealed substantial trait and state components. The contributions of genetic and environmental influences on the trait component were nearly equal, whereas environmental influences on the state component were much stronger than genetic influences. Although the overall findings were similar for older and younger twins, genetic influences on the trait component were stronger than environmental influences in younger twins, whereas the opposite was found for older twins. The current findings help to elucidate how the complex interplay between genetic and environmental factors contributes to both stability and change in neuroticism.
