Efficacy beliefs and communication are key constructs that have been targeted to develop task cohesion. This study’s purpose was to (a) examine whether collective efficacy, team-focused other-efficacy, and team-focused relation-inferred self-efficacy are predictive of task cohesion and (b) evaluate the possibility that communication mediates efficacy–task cohesion relationships. British university team-sport athletes (N = 250) completed questionnaires assessing efficacy beliefs, communication (i.e., positive conflict, negative conflict, and acceptance communication), and task cohesion (i.e., attractions to group, group integration). Data were subjected to a multigroup path analysis to test mediation hypotheses while also addressing potential differences across males and females. Across all athletes, collective efficacy and team-focused other-efficacy significantly predicted attractions to group and group integration directly. Positive conflict and acceptance communication significantly mediated relationships between efficacy (team-focused other-efficacy, collective efficacy) and cohesion (attractions to group, group integration). Findings suggest that enhancing athletes’ collective efficacy and team-focused efficacy beliefs will encourage communication factors affecting task cohesion.

效能信念和沟通是建立任务凝聚力的主要目标。这项研究的目的是（a）研究集体效能，以团队为中心的其他效能以及以团队为中心的关系推断的自我效能是否可预测任务的凝聚力，以及（b）评估交流介导功效-任务凝聚力关系的可能性。英国大学运动队运动员（N = 250）已完成的问卷，用于评估效能信念，沟通（即积极冲突，消极冲突和接受沟通）和任务凝聚力（即对团队的吸引力，团队整合）。数据经过多组路径分析以检验中介假设，同时还解决了男性和女性之间的潜在差异。在所有运动员中，集体效能和以团队为中心的其他效能显着地直接预测了团体和团体融合的吸引力。积极的冲突和接受沟通显着地介导了效能（以团队为中心的其他效能，集体效能）和凝聚力（吸引群体，整合群体）之间的关系。
