Full Length ArticleThe Big Five personality traits, Big Two metatraits and social media: A meta-analysis

- Plasticity positively predicted all SNS activities.
- Stability negatively predicted all SNS activities except for SNS interaction.
- Only extraversion and neuroticism were significantly associated with global SNS use.
- Openness was positively linked to most SNS activities.
- Conscientiousness was negatively related to SNS gaming and information seeking.

This article reported a meta-analysis of the relationships between social network site use and the Big Five (neuroticism, extraversion, openness, agreeableness, and conscientiousness) as well as the Big Two (plasticity and stability) personality meta-traits. A random effect meta-analysis model was used to calculate the meta-results of Big Five. Extraversion and openness were the strongest predictor of SNS activities (e.g. gaming, SNS interaction, etc.), while conscientiousness, neuroticism, and agreeableness only correlated with a few of the SNS activities. A meta-analytical structural equation model further demonstrated that plasticity was positively correlated with SNS activities, whereas stability was a negative predictor. Practical implications for social media industry and users were discussed.
