Problematic Social Media Use

This thesis is comprised of four studies. Study 1 was a meta-analysis of studies investigating the relationships between the five-factor personality traits and problematic social media use. Study 2 was a meta-analysis of studies investigating the relationship between trait mindfulness and problematic social media use. Studies 3 and 4 applied theoretical models of addictive behaviour to investigate problematic social media use operationalised as social media addiction. Study 3 investigated whether social media engagement and social media reward expectancies are associated with social media addiction. Study 4 investigated whether the relationships between social media addiction and various psychological predictors of social media addiction are mediated by positive and negative metacognitions regarding social media use. <br> The full datafiles used to conduct the meta-analyses in Study 1 and Study 2 are uploaded in this dataset.<br> The research materials used to gather data for Study 3 and Study 4 are uploaded in this dataset.<br> The datafiles used to analyse the data for Study 3 and Study 4 are uploaded in this dataset.
