Collective efficacy is a promising theoretical construct that has been used to explain bullying rates in school. The development of school collective efficacy scales has increased in bullying research in recent years; however, gaps remain in measuring collective efficacy to handle bullying. This research assessed the psychometric properties of a new scale to evaluate collective efficacy against bullying. This first-order one-dimensional scale is called the teachers' perceptions of collective efficacy to handle bullying (TCEB) scale. A sample of 804 Mexican primary teachers completed questionnaires. The sample was randomly split into two subsamples for calibration ( = 402) and cross-validation analysis ( = 402). The factor structure was supported by confirmatory factorial analysis. Measurement equivalence was confirmed by gender. The latent means differences showed no statistically significant differences by teachers' gender. The TCEB correlation with school environment factors (e.g., principal support, school climate, and bullying) confirms the scale's discriminant and concurrent validity. Our findings suggest that TCEB is a suitable instrument to assess teachers' perceptions of collective efficacy to handle bullying, a construct that has proved to help predict a positive whole-school context and student bullying involvement.
集体效能是一个有前途的理论构建，已被用于解释学校中的欺凌率。近年来，学校集体效能量表的发展在欺凌研究中有所增加；然而，在衡量处理欺凌问题的集体效能方面仍存在差距。本研究评估了一种新的评估集体效能以应对欺凌的量表的心理测量学特性。这个一阶一维量表称为教师对处理欺凌的集体效能感知量表（TCEB）。804 名墨西哥小学教师完成了问卷调查。该样本被随机分为两个子样本进行校准（n=402）和交叉验证分析（n=402）。验证性因素分析支持了该量表的因子结构。通过性别确认了测量等效性。潜在均值差异显示，教师性别之间没有统计学上的显著差异。TCEB 与学校环境因素（如校长支持、学校氛围和欺凌）的相关性证实了该量表的区分度和同时效度。我们的研究结果表明，TCEB 是一种评估教师对处理欺凌的集体效能感知的合适工具，该构念已被证明有助于预测积极的全校环境和学生欺凌参与。
