Abstract
Prior behavioral genetic studies in positive psychology were entirely based on data from Western democracies leaving the question open whether the magnitude of genetic effects on wellbeing indicators is similar in substantially different societal contexts The aim of this study therefore was to investigate the structure of the genetic and environmental influences on happiness life satisfaction meaning in life optimism sense of coherence and general wellbeing in a nonWestern sample Altogether 100 monozygotic and 36 samesex dizygotic twin pairs from Hungary 73 female Mage = 43 years SD = 16 years participated in the survey Univariate classical twin modeling ACE analysis was performed using structural equation models Heritability estimates of the positive psychological variables were largely variable ranging from 0 happiness and meaning in life to 67 life satisfaction Also estimates for the influence of common environment fell between 0 life satisfaction sense of coherence and wellbeing and 60 meaning in life Unshared environmental influences however explained a moderate variance of all investigated variables 33–62 Most results were in line with previous findings from Western countries however some notable differences—eg lower hereditary influence for happiness or more robust role of shared environmental effects for optimism—were also established These findings suggest that the communist and postcommunist legacy did not produce drastic differences in the structure of heritability and environmental influences as compared to countries with longer traditions of democracy and economic prosperityThe study was supported by Medexpert Ltd The first author also gratefully acknowledges the financial support of the Norlien Foundation and the IMPART program Intersections of Mental Health Perspectives in Addictions Research Training received while working on this paper
