The aim of this research was to examine the relationship between social support from family, vulnerable narcissism, socially prescribed perfectionism, social connectedness, and resilience in adolescents and young adults. A total of 466 participants took part in the research, with 159 (34.1%) identifying as male and 307 (65.9%) as female, ranging in age from 18 to 35. The sample was convenient, and participants were collected through social networks, where a link to the form containing sociodemographic questions, scale of social support from family, scale of socially prescribed perfectionism, scale of vulnerable narcissism, scale of social connectedness and resilience scale was shared. The results indicated that social support from family was a significant predictor of socially prescribed perfectionism and vulnerable narcissism. Specifically, higher perceived emotional support from family and family support of ones self-esteem predicted lower levels of socially prescribed perfectionism and vulnerable narcissism. Additionally, predictors of resilience were analyzed, with socially prescribed perfectionism and vulnerable narcissism emerging as significant predictors of resilience. That is, higher levels of socially prescribed perfectionism and vulnerable narcissism predicted lower resilience. Finally, the mediating role of social connectedness in the relationship between socially prescribed perfectionism and resilience, and vulnerable narcissism and resilience, was analyzed and found to be significant in both cases. In other words, individuals with higher levels of socially prescribed perfectionism and vulnerable narcissism exhibited lower resilience through perceived lower social connectedness. Based on the results, the research discusses potential theoretical conclusions derived from the research, as well as practical implications aimed at strengthening the resilience of young adults.
