Social Media Use and Depression and Anxiety Symptoms: A Cluster Analysis.

Objectives: Individuals use social media with varying quantity, emotional and behavioral attachment that may have differential associations with mental health outcomes. In this study, we sought to identify distinct patterns of social media use (SMU) and to assess associations between those patterns and depression and anxiety symptoms. Methods: In October 2014, a nationally-representative sample of 1730 US adults ages 19 to 32 completed an online survey. Cluster analysis was used to identify patterns of SMU. Depression and anxiety were measured using respective 4-item Patient-Reported Outcome Measurement Information System (PROMIS) scales. Multivariable logistic regression models were used to assess associations between cluster membership and depression and anxiety. Results: Cluster analysis yielded a 5-cluster solution. Participants were characterized as "Wired", "Connected", "Diffuse Dabblers", "Concentrated Dabblers" and "Unplugged". Membership in 2 clusters - "Wired" and "Connected" - increased the odds of elevated depression and anxiety symptoms (AOR = 2.7, 95% CI = 1.5-4.7; AOR = 3.7, 95% CI = 2.1-6.5, respectively and AOR = 2.0, 95% CI = 1.3-3.2; AOR = 2.0, 95% CI = 1.3-3.1, respectively). Conclusions: SMU pattern characterization of a large population suggests 2 patterns are associated with risk for depression and anxiety. Developing educational interventions that address use patterns rather than single aspects of SMU (eg, quantity) would likely be useful. [ABSTRACT FROM AUTHOR]
