This poster presentation explores the specific risk for problems in gambling and financial trading that stem from interpersonal contexts, based on findings from an online survey conducted via Amazon’s MTurk (N = 581). Results show that fear of missing out (FOMO)—defined as a pervasive concern about missing rewarding experiences others might be having, along with anti-mattering (i.e., sense of being invisible to others), and competitiveness significantly influences problematic behaviors in gambling and financial trading. Furthermore, based on profiles of the risk factors, four distinct latent groups were identified, each exhibiting notable differences in problem gambling and financial trading behaviors.
