Personality traits and perception of parenting: The comparative twin study from Germany and Serbia

This study examines the aetiology of the relationship between personality traits and perceived parenting in light of cross-cultural differences. The sample consisted of 188 Serbian and 394 German twin pairs. Personality traits were measured using the NEO-personality inventory. A Blocks Environmental Questionnaire (BEQ) was applied to measure two dimensions of perceived parenting: support and organisation. Genetic factors account for 63-79% of the variance for BEQ dimensions in both samples, while around 50-60% of the variance in Big Five personality scores could be attributed to genetic factors. The exception was Neuroticism in the Serbian sample, where the genetic effect was somewhat smaller. The results indicated similar etiological pathways of the relationship between personality traits and perceived parenting, with some cultural differences related to Neuroticism and Extraversion. Negative Neuroticism-Support and positive Extraversion-Organisation environmental relationships were stronger in the Serbian sample. Genetic overlaps were more significant in the German sample, except for the relationship of Organisation with Conscientiousness and Extraversion. This indicates that the relationship between personality and perceived parenting is largely genetically mediated, but that the environmental effect may play an important role in individual adaptation to the family setting.
