Impulsiveness as potential moderators of the relation between social media dependence and eating disorders risk

BMC Psychol. 2022 May 8;10(1):120. doi: 10.1186/s40359-022-00830-8.

Abstract

Background: Social media dependence (SMD) and eating disorders (ED) risk are often thought to be inextricably linked. Because social media dependence often precedes an ED, predicts poor outcome, and persists even after recovery from an ED, it is important to examine whether certain factors have the ability to potentially attenuate or intensify SMD's effect on eating disorders.

Methods: In the current study, we examined one possible moderating factor: impulsiveness. 767 undergraduates (mean age = 18.78 years, SD = 1.20) in Shaanxi province of China, completed anonymous questionnaires regarding social media dependence, eating disorders, impulsiveness.

Results: Revealed that non-planned impulsiveness (NPI) moderated the relation between SMD and ED risk. Individuals who were low in SMD and who reported low levels of NPI reported much lower levels of ED risk than those with low SMD and high NPI. However, Individuals who were high in SMD and who reported low levels of NPI reported much higher levels of ED risk than those with high SMD and high NPI. Contrary to our hypotheses, Motor impulsiveness and cognitive impulsiveness did not emerge as moderators of the relation between SMD and ED risk.

Conclusions: Results provide growing support that factors that interact with SMD can lessen or aggravate SMD's effect on ED risk. These findings can be beneficial to our understanding of how and when social media dependence impacts undergraduates' eating disorders risk.
