This study aimed to examine the relationship between the FOBO effect and psychosocial correlates - maximization, regret, information overload, and perceived stress. FOBO (Fear of a Better Option), or the fear of missing out on a better option, is defined as the impulse to postpone decision-making out of fear that a better choice might emerge. The study involved 224 participants, 145 females and 79 males. According to the results of the study, the FOBO effect is positively associated with maximization, regret, and information overload. In other words, individuals who delay decisions out of fear that a better option will come along tend to maximize their choices, experience regret after making decisions, and become more burdened by information. The FOBO effect emerged as a significant predictor of perceived stress in individuals. Additionally, a partial complementary mediation was found between the relationship of the FOBO effect and perceived stress, with information overload as a mediator of this relationship. Hence, individuals who exhibit the FOBO effect are more likely to perceive higher levels of stress when making decisions. Those with pronounced FOBO tend to engage in constant information analysis regarding existing and potential options, which leads to information overload and, consequently, a heightened perception of stress.A contribution of this study is the construction of the FOBO effect scale, which has proven to be highly reliable. However, it is necessary to replicate the study on a larger sample with an equal number of men and women.
