The Collective Efficacy Scale Short-Form (CES-SF) is a short and reliable instrument that assesses collective efficacy in schools at a group level. Previous research has shown a two-factor structure considering the perception of the group competence about their teaching capabilities and task analysis that refers to the opportunities inherent to a specific task. However, there is no conclusive evidence that collective efficacy corresponds to a two-factor model or single-factor structure.
A cross-sectional research was conducted on a 693 sample of teachers ( = 39.4; SD = 11.8) from schools in the 16 regions of Chile. They were assessed using the CES-SF, Personal Well-being Index, Social Well-Being Scale, and satisfaction with the school. Exploratory and confirmatory factor analyses were used to assess the construct validity of the CES-SF.
The CES-SF showed mixed results about its construct validity. Best fit has been found to retain two new factors (opportunities and challenges for collective efficacy) with eight items each, yielding a McDonald's ω of 0.803. Convergent validity was also established.
The psychometric results suggest that a two-factor structure for the CES-SF is a valid and reliable measure for this construct for Chilean teachers. However, collective efficacy might not strongly relate to subjective wellbeing but to school-context variables.
集体效能感量表简版（CES-SF）是一种简短且可靠的工具，用于在群体层面评估学校中的集体效能感。先前的研究表明，其具有两因素结构，一个因素是对群体教学能力的感知，另一个因素是任务分析，涉及特定任务所固有的机会。然而，尚无确凿证据表明集体效能感对应于两因素模型或单因素结构。
对来自智利16个地区学校的693名教师样本（平均年龄 = 39.4岁；标准差 = 11.8）进行了横断面研究。使用CES-SF、个人幸福感指数、社会幸福感量表以及对学校的满意度对他们进行评估。采用探索性和验证性因素分析来评估CES-SF的结构效度。
CES-SF在结构效度方面呈现出混合结果。发现保留两个新因素（集体效能感的机会和挑战）、每个因素包含八个项目时拟合最佳，麦克唐纳ω系数为0.803。同时也建立了收敛效度。
心理测量结果表明，CES-SF的两因素结构对于智利教师的这一构念是一种有效且可靠的测量方法。然而，集体效能感可能与主观幸福感的关联不强，而是与学校背景变量有关。
