Case-control study of student-perpetrated physical violence against educators

摘要

Purpose: Although prior research focused primarily on student-on-student school violence, educators are also at risk. This study was designed to identify risk factors for assaults against educators. Methods: Kindergarten-grade 12 educators (n = 26,000), randomly selected from a state license database, were screened for eligibility (6,469, eligible) by mailed questionnaire. Phase 1 (12-month recall) identified eligible assault cases (n = 372) and controls (n = 1,116), June 2004 to December 2005; phase 2 (case-control study; response, 78%) enabled identification of exposures through 1-month recall before student-perpetrated assaults (cases) and randomly selected months (controls). Directed acyclic graphs enabled confounder selection for multivariable logistic regression analyses; reweighting adjusted for potential biases. Results: Risks (odds ratios, 95% confidence intervals) increased for working in: Special Education (5.84; 4.07-8.39) and School Social Work (7.18; 2.72-18.91); kindergarten to second grade (1.81; 1.18-2.77); urban (1.95; 1.38-2.76) schools; schools with less than 50 (8.40; 3.12-22.63), 50-200 (3.67; 1.84-7.34), 201-500 (2.09; 1.32-3.29), and 501-1000 (1.94; 1.25-3.01) students versus more than 1000; schools with inadequate resources always/frequently (1.62; 1.05-2.48) versus infrequentlyever; inadequate building safety always/frequently (4.48; 2.54-7.90) versus infrequentlyever; and environments with physical barriers (1.50; 1.07-2.10). Risks decreased with routine locker searches (0.49; 0.29-0.85) and accessible exits (0.36; 0.17-0.74). Conclusions: Identification of assault risk factors provides a basis for further investigation and interventions.
