Adaptation of the Group-Leader Self-Assessment (GLSA) Scale into Turkish
Abstract
This study aimed to adapt the Group Leader Self-Assessment (GLSA) scale (Barnes et al., 2020) into Turkish and examine its psychometric properties. To ensure high methodological rigor, the construct validity was tested using two independent samples: Exploratory Factor Analysis (EFA) was conducted with a sample of N1=215, while Confirmatory Factor Analysis (CFA) was performed with a separate sample of N2=101. EFA results revealed a 29-item, five-factor structure, and CFA results confirmed that this model provided a better fit for the Turkish context (RMSEA = .085, CFI = .91, SRMR = .065) than the original four-factor model. Concurrent validity was supported by a significant positive correlation (r = .56, p < .001) with the Group Work Skills Scale. The scale demonstrated excellent internal consistency with a Cronbach’s alpha coefficient of .96. Overall, the Turkish version of the GLSA is a methodologically robust, valid, and reliable instrument for assessing the self-perceived competencies of group leaders in various professional settings.
