We investigated the relationship between body mass index (BMI) and personality traits, socioeconomic status (SES), and body image (BI) at the beginning of preadolescence. Data were collected from 238 Italian children aged 10-11 years using self-report scales. Information about SES was derived from parental education and professional status. BI was the variable the most strongly associated with BMI. Controlling for BI, SES, and gender, Agreeableness was inversely associated with BMI, whilst Extroversion was related to BMI in girls only. Gender did not moderate the associations between BI and BMI at this age. The relationship of certain personality traits with BMI is likely to emerge during preadolescence. Early interventions to reduce overweight and obesity could consider the interplay of Agreeableness and Extroversion with gender, BI, and SES.
In recent decades, given new forms of political participation, the involvement of young people in the civic domain begins to be a focus of many studies. The present study examined the role of personality traits and personal values in the prediction of civic engagement (CE) in Italian youth ranging in age from 19 to 29 years old involved in an ongoing longitudinal study. The multidimensionality of a scale tapping CE has been demonstrated with the examination of confirmatory factor analysis. Structural equation modeling corroborated a mediational model in which benevolence fully mediated the relationship of the traits of agreeableness and openness with civic associationism, whereas power fully mediated the relationship of the traits of agreeableness and openness with political associationism. In this mediational model men reported higher levels of power than women, whereas women reported higher levels of agreeableness and openness traits. Since basic personal traits have been identified as the root of any behavioral tendency and values have been recognized as the more flexible and changeable variables, future interventions aimed to foster CE in youth could be designed considering the strength relationship between the examined dimensions in the present study.
