The aim of this study was to examine the relationship between parenting dimensions (involvement/acceptance vs. strictness/imposition) and school victimization, considering the possible mediating role of social anxiety. The sample comprised 887 adolescents (52.3% girls) aged between 12 and 16 (M = 13.84 and SD = 1.22) enrolled at three compulsory secondary education ("ESO" or "Educación Secundaria Obligatoria" in Spanish) schools located in the provinces of Valencia, Teruel and Seville (Spain). A structural equations model was developed using the Mplus 7.4 program. The results obtained indicate that social anxiety mediates the relationship between parenting dimensions (involvement/acceptance vs. strictness/imposition) and school victimization. Finally, the results and their potential theoretical and practical implications are discussed.
