The aim of the study was to clarify whether personality traits predict the structure, function and quality of egocentric confidant networks in later life. Data were drawn from Waves 7 and 8 of the Survey of Health, Ageing and Retirement in Europe (SHARE) (N = 39,172). We regressed network size, contact frequency and network satisfaction on the Big-5 personality traits, using a single path analysis structure, controlling for country, sociodemographic background and health status. The findings showed that the personality traits were related to the social network outcomes, but their effect was modest and less predictive than the contextual factors. The country predictors explained the most variance, generally, with some surprising results. For example, confidant networks were the largest in Scandinavia and Central Europe, and smallest in the Mediterranean region and Eastern Europe. Among the personality traits, extraversion was the most consistent positive predictor, but conscientiousness was also predictive. Neuroticism was a negative predictor, but not of network size. The sociodemographic variables, particularly partner status, explained more variance than the personality traits did. In sum, the SHARE database offers a comprehensive and differentiated view of the complex interpersonal milieus in which older Europeans are embedded.
