Abstract

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 infrequently/never; inadequate building safety always/frequently (4.48; 2.54-7.90) versus infrequently/never; 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.

摘要

目的

尽管先前的研究主要集中在学生之间的校园暴力上，但教育工作者也面临着风险。本研究旨在确定针对教育工作者的攻击的危险因素。

方法

从州许可数据库中随机抽取幼儿园至 12 年级的教育工作者（n=26000），通过邮寄问卷进行资格筛选（6469 名合格者）。第 1 阶段（12 个月的回溯）确定了合格的攻击案例（n=372）和对照（n=1116），时间为 2004 年 6 月至 2005 年 12 月；第 2 阶段（病例对照研究；响应率为 78%）通过回溯到学生实施攻击（病例）之前的 1 个月和随机选择的月份（对照）来确定暴露情况。有向无环图用于多变量逻辑回归分析中的混杂因素选择；重新加权用于调整潜在偏差。

结果

在以下情况下，工作风险（优势比，95%置信区间）增加：特殊教育（5.84；4.07-8.39）和学校社会工作（7.18；2.72-18.91）；幼儿园至二年级（1.81；1.18-2.77）；城市（1.95；1.38-2.76）学校；学生人数少于 500（8.40；3.12-22.63）、500-2000（3.67；1.84-7.34）、2001-5000（2.09；1.32-3.29）和 5001-10000（1.94；1.25-3.01）与超过 10000 名学生的学校；资源总是/经常不足（1.62；1.05-2.48）与不经常/从不；建筑安全总是/经常不足（4.48；2.54-7.90）与不经常/从不；以及有物理障碍的环境（1.50；1.07-2.10）。风险随着常规储物柜检查（0.49；0.29-0.85）和可进入的出口（0.36；0.17-0.74）而降低。
