Mediating effect of depression between problematic social media use and body dysmorphic concerns in adolescents.

Background: Adolescence is a critical period during which there is a concerning rise in the incidence of mental health problems, including depression and body dysmorphic concerns symptoms, as well as addictive behaviors such as problematic social media use. The objective of this research is to examine the role of depression as a mediator between problematic social media use and body dysmorphic concerns.

Methods: This study used a cross-sectional design and recruited a total of 336 Lebanese adolescents, aged 15 to 18, with an average age of 15.69 ± 1.10 years and 63.4% of them being female, from all governorates of Lebanon between the months of December 2023 and January 2024. The statistical analysis was performed utilizing version 25 of the SPSS program. Two categorical variables were compared using the Chi-square test, and two means were examined using the Student t test. Model 4 of the PROCESS MACRO, an add-on for SPSS, was utilized to conduct the mediation analysis.

Results: After adjusting for age and sex, depression was found to partially mediate the association between problematic social media use and body dysmorphic concerns (indirect effect: Beta = .48; Boot SE = .08; Boot CI .33; .65). Higher PSMU was significantly associated with more depression and directly associated with more body dysmorphic concerns.

Conclusion: This study has shown, for the first time that depression may act as a mediator in the relationship between problematic social media use and Body dysmorphic disorder. Recognizing this malleable factor as a mediator might provide new understanding for psychiatric therapies conducted on persons who are likely to display signs of dysmorphia when they utilize social media in an addictive pattern.
