The Big Five,self-esteem,and narcissism as predictors of the topics people write about in Facebook status updates

Status updates are one of the most popular features of Facebook, but few studies have examined the traits and motives that influence the topics that people choose to update about. In this study, 555 Facebook users completed measures of the Big Five, self-esteem, narcissism, motives for using Facebook, and frequency of updating about a range of topics. Results revealed that extraverts more frequently updated about their social activities and everyday life, which was motivated by their use of Facebook to communicate and connect with others. People high in openness were more likely to update about intellectual topics, consistent with their use of Facebook for sharing information. Participants who were low in self-esteem were more likely to update about romantic partners, whereas those who were high in conscientiousness were more likely to update about their children. Narcissists’ use of Facebook for attention-seeking and validation explained their greater likelihood of updating about their accomplishments and their diet and exercise routine. Furthermore, narcissists’ tendency to update about their accomplishments explained the greater number of likes and comments that they reported receiving to their updates.     

Psychological and social functioning are associated with reports of perceived weight discrimination across eight years

This research uses the Health and Retirement Study to identify psychological and social factors that prospectively predict new reports of perceived weight discrimination among individuals who measure in the obese weight category. Participants (M_age = 66.89, SD = 8.33; 58% women) reported on their personality and social isolation, had a body mass index (BMI) ≥ 30, reported no perceived weight discrimination at baseline, and completed at least one assessment over the up to 8-year follow-up (N = 3,064). Eleven percent of participants reported new experiences of perceived weight discrimination. Higher Neuroticism and loneliness at baseline were associated with new reports; Conscientiousness was protective. This research adds to models of weight stigma by identifying psychological and social factors that contribute to reporting new instances of perceived weight discrimination.
