Previous studies found that addictive social media use is associated with negative consequences such as reduced productivity, unhealthy social relationships, and reduced life-satisfaction. However, a holistic theoretical understanding of how social media addiction develops is still lacking, which impedes practical research that aims at designing educational and other intervention programs to prevent social media addiction. In this study, we reviewed 25 distinct theories/models that guided the research design of 55 empirical studies of social media addiction to identify theoretical perspectives and constructs that have been examined to explain the development of social media addiction. Limitations of the existing theoretical frameworks were identified, and future research areas are proposed. Gambling Disorder (GD) and Posttraumatic Stress Disorder (PTSD) are frequently comorbid and often associated with a more severe clinical profile compared to those with either diagnosis alone. Despite recent growing interest in this comorbidity, there has been little effort to synthesize this domain of research and define areas of need for future research. The present work details a systematic review of empirical studies examining the relationship between PTSD and GD-related factors. This review encompassed 74 studies each examining the overlap between GD and the following domains PTSD, Trauma, Adverse Childhood Experiences, and Stressful Life Events. The included studies yielded 91 independent samples each providing associations between the above-mentioned constructs. The present work found that stress, trauma, and symptom severity of PTSD each influence the severity of both GD and subclinical levels o
