Converging evidence across multiple analyses suggests that secure school building policies may not be systematically linked to school disorder and may be more a reactive measure in response to other concerns. Most importantly, measures of incivility explain almost double the variance (31-45 percent vs. 17-25 percent) in students' fear, anxiety, and avoidant behaviors, compared to theft and attack, when tested using alternate measurement models. The analysis can inform school-based professionals working with at-risk students who may be exhibiting fear, anxiety, or avoidant behaviors related to a hostile school environment. The findings suggest that local school personnel and educational leaders concerned about school violence should facilitate increased resource supports to address incivility in schools. 2 figures, 2 tables, 5 notes, and 51 references (Published abstract)
