✦ Synopsis

Several studies have found a genetic in¯uence on person  situation interactions of behaviours and emotions. For ®ve situations we assessed current positive and negative mood for a sample of 168 monozygotic and 132 dizygotic adult twin pairs completing self-report rating scales. We used structural equation model ®tting to estimate genetic and environmental in¯uences on the stability and variability of moods across situations. Our results indicate that genetic as well as shared and nonshared environmental in¯uences contribute to the consistency of moods. Contrary to previous ®ndings, the variability of positive and negative mood is mainly attributed to nonshared environmental in¯uences and only marginally attributed to genetic or shared environmental eects.
