Resumo: | The aim of this study is to adapt and consequently validate the Global Transformational Leadership mea-suring scale (GTL). The scale was therefore applied to a sample of 456 members of 70 work groups,belonging to 26 organizations. The factorial structure of the scale was analysed through the exploratoryfactor analysis (EFA) and confirmatory factor analysis (CFA), with the sample being split in two equalparts: EFA was conducted in both sub-samples and CFA was applied in the second sub-sample. The inter-nal consistency was evaluated via Cronbach’s alpha and the nomological validity was analysed via theevaluation of the GTL’s correlations with both team-level autonomy and quality of group experience.The results revealed the presence of a unidimensional scale with a good level of internal consistency.Regarding the nomological validity, the results pointed to hypothetical relations, since the GTL showedpositive correlations with the variables considered. Thus, the Portuguese version of the GTL is presentedas a useful instrument for evaluating transformational leadership. |

La escala se aplicó a una muestra de 456 miembros de 70 grupos de trabajo,pertenecientes a 26 organizaciones. La estructura factorial fue analizada mediante el análisis factorialexploratorio (AFE) y el análisis factorial confirmatorio (AFC), después de dividir la muestra en dos partesiguales: la AFE se aplicó en las dos muestras y la CFA en la segunda muestra. La consistencia interna seevaluó mediante el alfa de Cronbach y la validez nomológica se analizó mediante las correlaciones de GTLcon la autonomía del grupo y la calidad de la experiencia del grupo. Los resultados revelaron la presen-cia de una escala unidimensional com un buen nivel de consistencia interna. Los datos sobre la valideznomológica confirmaron las relaciones previstas, habiendo presentado la GTL correlaciones positivas conlas variables consideradas. La version portuguesa de la GTL se presenta como una herramienta útil paraevaluar el liderazgo transformacional.2017info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttp://hdl.handle.net/10316/102106http://hdl.handle.net/10316/102106https://doi.org/10.1016/j.rpto.2017.02.004eng15765962van Beveren, PatríciaDimas, Isabel DórdioLourenço, Paulo RenatoRebelo, Teresainfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2022-09-26T21:22:33Zoai:estudogeral.uc.pt:10316/102106Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T21:19:10.183311Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
