The study focused on data obtained from Belgium's 1998 Safety Monitor, the second edition of a Federal computer-assisted telephone interview survey that included responses to questions on fear of crime. The sample size for the study was 2,917, of whom 1,495 were Flemish-speaking and 1,422 were French-speaking. The Safety Monitor used four indicators to measure fear of crime: avoidance of certain neighborhood areas considered unsafe, not opening the door to strangers at night as a security measure, avoiding leaving home at night, and having feelings of being unsafe. Perceptions of physical incivilities in the neighborhood were measured with two items: perception of litter in the street and "dog dirt in the street." Other items measured perceptions of threat in the neighborhood and perceptions of police effectiveness. Assessment of cross-cultural invariance within the aforementioned concepts used confirmatory factor analysis in a linear structural equation approach (LISREL 8.50). A theoretically relevant exploratory model with fear of crime as the dependent variable was tested. Both the dependent and independent constructs in the model were assessed for their cross-cultural equivalence. In principle, this produces a model that is free from cultural bias. The current study found no evidence of measurement variance between the two cultural groups. 1 table, 4 figures, and 46 references
