AimIf we want to understand people’s satisfaction in their relationships, it is essential to have a valid and reliable measure of relational needs satisfaction. The aim of this study was to test the factor structure of the Czech version of the Relational Needs Satisfaction Scale as well as the scale’s measurement invariance and convergent validity.MethodIn total, 419 adults answered a battery of measures, including the RNSS, in an online survey. Confirmatory factor analysis was conducted to test the factor structure and (...) the measurement invariance of the RNSS across gender and age. A correlational analysis was conducted to assess the convergent validity.ResultsThe five-factor structure of the RNSS was confirmed. Furthermore, support for a second-order global relationship satisfaction factor was found. The hierarchical model was strictly invariant with respect to gender and age. Furthermore, the RNSS demonstrated an expected pattern of correlations with the reference instruments.ConclusionThe Czech version of the RNSS can be considered a valid and reliable method. (shrink)

The Group Cohesiveness Scale 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 supported a two-dimensional solution. The analysis demonstrated the existence of two moderately to highly associated domains of group cohesiveness—affective and behavioral. The two-dimensional model was invariant across genders, age, education, and time (...) up to factor means level. Internal consistency reached satisfactory values for both domains. 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. 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. (shrink)
