RT Journal Article T1 The dark side of Instagram: Predictor model of dysmorphic concerns. A1 Senín-Calderón, Cristina A1 Perona-Garcelán, Salvador A1 Rodríguez-Testal, Juan F K1 Appearance-related comparisons K1 Cross-sectional study K1 Difficulties in emotion regulation K1 Dysmorphic concerns K1 Instagram use AB Dysmorphic concern are excessive preoccupation about one or several physical characteristics perceived as defects, usually unnoticeable by others. This study was intended to explore the relationship between Instagram use and dysmorphic concerns through appearance-related comparisons, ideas of reference and problems with emotion regulation, and find out whether this relationship is moderated by gender. The sample was comprised of 796 participants (Mage  = 22.49; SD = 3.56; 54% women). The results showed a non-significant direct effect between Instagram use and dysmorphic concerns. However, the relationship between these variables was statistically significant through appearance-related comparisons, ideas of reference about "laughing, commenting" and difficulties in emotion regulation. Gender did not moderate any relationship. Men and women who made the most use of Instagram were equally vulnerable to dysmorphic concerns when they tended to compare their appearance with other users, had problems regulating their emotions, and showed interpretative biases related to the belief that others could make comments about them or laugh at them because of their imperfections. The implications of the study are discussed. YR 2020 FD 2020-08-23 LK https://hdl.handle.net/10668/27418 UL https://hdl.handle.net/10668/27418 LA en DS RISalud RD Apr 10, 2025
