Collective efficacy, defined as a group’s shared belief about its conjoint capability to organize and execute courses of action, plays a pivotal role in understanding the dynamics of sports teams, since it influences what individuals choose to do as team members, how much they invest in motivational terms to perform actions, how much they work collectively, and for how long they persist despite failure. Through a systematic review, it was investigated how collective efficacy has been assessed in the context of soccer and which indicators, attributes, and psychometric properties have been contemplated in the instruments used. Following the PRISMA guidelines, 22 articles were retrieved through electronic databases (APA PsycINFO; SPORTDiscus; Science Direct; BVS; Web of Science; Scopus; PubMed; and Scielo), using as descriptors, in English, Spanish, and Portuguese, collective efficacy and soccer, combined by the Boolean operators AND and OR. The study did not delimit the initial year of publication for the searches carried out, including all articles found until January 14, 2021 (date of the last update). The following eligibility criteria were adopted: scientific articles published in journals; original studies, which specified the instrument used to assess collective efficacy and carried out with soccer athletes. Five instruments (FCEQ, CEQS, CEI, CEC, and CEQsoccer) that evaluated technical-tactical and psychological attributes associated with collective efficacy in soccer players were identified. In most studies, psychometric properties were restricted to content validity and reliability (internal consistency), and there were no suitable validation processes for the instruments used to measure collective efficacy, which can be considered a limiting factor for understanding this psychological construct in soccer modality.

足球队的集体效能：系统评价

集体效能，被定义为一个群体对其组织和执行行动方案的联合能力的共同信念，在理解运动队的动态方面起着关键作用，因为它影响个人作为团队成员选择做什么，他们投资多少执行行动的动机术语，他们集体工作的程度，以及他们在失败后坚持的时间。通过系统审查，调查了如何在足球背景下评估集体效能，以及在所使用的工具中考虑了哪些指标、属性和心理测量特性。遵循 PRISMA 指南，通过电子数据库（APA PsycINFO；SPORTDiscus；Science Direct；BVS；Web of Science；Scopus；PubMed；和 Scielo）检索了 22 篇文章，使用英语、西班牙语、和葡萄牙语、集体效力和足球，由布尔运算符 AND 和 OR 组合。该研究没有界定所进行搜索的最初发表年份，包括在 2021 年 1 月 14 日（上次更新日期）之前找到的所有文章。采用了以下资格标准： 在期刊上发表的科学文章；原始研究，其中指定了用于评估集体效能的工具，并在足球运动员中进行。确定了五种评估与足球运动员集体效能相关的技术-战术和心理属性的工具（FCEQ、CEQS、CEI、CEC 和 CEQsoccer）。在大多数研究中，心理测量属性仅限于内容有效性和可靠性（内部一致性），
