Many studies have been conducted to examine the predictors of fear of crime among adults, but feelings of insecurity among children and adolescents have been practically ignored. The aim of this study is to search for relevant determinants of fear of crime in a representative sample of 1,212 Flemish (Belgian) adolescents, age 14 to 18, and one of their parents. The effect of parenting styles on the child's level of fear is investigated by means of (multi-group) structural equation modeling. The level of parental supervision (especially fathers) is associated with more fears being experienced by children. Active parental stimulation of participation in organized leisure activities results in lower levels of fear among female children. Parents who focus on independence and autonomy, in contrast, seem to raise boys who have lower degrees of fear. Other findings that relate to fear of crime in adolescence, such as gender differences and socialization, media and leisure patterns, and victimization and personal adjustment, are also discussed.
