The Group Cohesiveness Scale (GCS, 7 items) measures patient-rated group cohesiveness. The English version of the scale has demonstrated good psychometric properties. This study describes the validation of the Czech version of the GCS. A total of 369 patients participated in the study. Unlike the original study, the ordinal confirmatory factor analysis (CFA) supported a two-dimensional solution (RMSEA = 0.075; TLI = 0.986). The analysis demonstrated the existence of two moderately to highly associated ( = 0.79) domains of group cohesiveness-affective and behavioral. The two-dimensional model was invariant across genders, age, education, and time (retest after 6 weeks) up to factor means level. Internal consistency reached satisfactory values for both domains (affective, ω = 0.86; behavioral, ω = 0.81). In terms of convergent validity, only weak association was found between the GCS domains and the group working alliance measured by the Group Outcome Rating Scale (GSRS). This is the first revision of the factor structure of the GCS in the European context. The scale showed that the Czech version of the GCS is a valid and reliable brief tool for measuring both aspects of group cohesiveness.
团体凝聚力量表（GCS，7个项目）用于测量患者评定的团体凝聚力。该量表的英文版已显示出良好的心理测量特性。本研究描述了GCS捷克语版的验证过程。共有369名患者参与了该研究。与原研究不同，有序验证性因素分析（CFA）支持二维解决方案（RMSEA = 0.075；TLI = 0.986）。分析表明存在两个中等至高度相关（= 0.79）的团体凝聚力领域——情感领域和行为领域。二维模型在性别、年龄、教育程度和时间（6周后重新测试）方面直至因素均值水平都是不变的。两个领域的内部一致性均达到了令人满意的值（情感领域，ω = 0.86；行为领域，ω = 0.81）。在收敛效度方面，GCS领域与团体结果评定量表（GSRS）测量的团体工作联盟之间仅发现微弱关联。这是欧洲背景下GCS因素结构的首次修订。该量表表明，GCS捷克语版是测量团体凝聚力两个方面的有效且可靠的简短工具。
