Childhood unpredictability and problematic internet pornography use among Chinese university students: a moderated serial mediation model

Background

Although previous studies have shown that childhood unpredictability affects problematic internet pornography use in college students, the fundamental mediating mechanisms and moderating boundary conditions have not been thoroughly investigated. Consequently, the current research aimed to determine whether life history strategy and body image serve as mediators in the link between childhood unpredictability and problematic internet pornography use, and whether these mediating pathways are influenced by perceived friend support.
