Problematic social networking site use: a brief review of recent research methods and the way forward.

Social networking site (SNS) use is a routine activity for millions of people around the world. Under certain circumstances, an increase in SNS use may lead to problematic social networking site use (PSNSU). Numerous studies have reported associations between PSNSU and various psychosocial variables. The present review briefly examines research methods that have been employed to investigate PSNSU. Cross-sectional studies have been a popular method of investigating PSNSU, but they have significant limitations. Longitudinal and neuroimaging studies may provide important insights, but they are more difficult to conduct and have been less utilised. The field would benefit from a clarification of research priorities, integration of research methods, and studies that include SNS users from various age groups.
