The Associations Between Parental Socio-Economic Conditions, Childhood Intelligence, Adult Personality Traits, Social Status and Mental Well-Being

This study explored a longitudinal data set of 5,090 adults examining the associations between parental social status indicators (measured at birth), childhood intelligence (measured at age 11), personality traits, educational achievement and occupational prestige in relation to mental well-being (all measured at age 50). Correlational analysis showed that parental social status indicators and childhood intelligence were significantly associated with all of the big five personality traits (extraversion, emotional stability, agreeableness, conscientiousness, and intellect). Parental social status indicators, childhood intelligence, personality traits, education and occupation were all significant correlates of mental well-being. Structural equation modelling showed childhood intelligence was significantly associated with all the five personality traits, and family social status (indicated by parental social class, and paternal and maternal education) was significantly associated with traits intellect, extraversion, and agreeableness. All the five personality traits were significant predictors of mental well-being after taking into account the effects of family social status, childhood intelligence, own education achievement and current occupational prestige. Implications and limitations are discussed.
