Psychometric properties of the Portuguese version of the Global Transformational Leadership (GTL) scale / Propiedades psicométricas de la versión portuguesa de la escala Global Transformational Leadership (GTL)

The aim of this study is to adapt and consequently validate the Global Transformational Leadership measuring 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 exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), with the sample being split in two equal parts: EFA was conducted in both sub-samples and CFA was applied in the second sub-sample. The internal consistency was evaluated via Cronbach's alpha and the nomological validity was analysed via the evaluation 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 showed positive correlations with the variables considered. Thus, the Portuguese version of the GTL is presented as a useful instrument for evaluating transformational leadership (AU)

El objetivo de este estudio fue adaptar y, consecuentemente, validar al portugués la escala Global Transformational Leadership (GTL). 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 factorial exploratorio (AFE) y el análisis factorial confirmatorio (AFC), después de dividir la muestra en dos partes iguales: la AFE se aplicó en las dos muestras y la CFA en la segunda muestra. La consistencia interna se evaluó mediante el alfa de Cronbach y la validez nomológica se analizó mediante las correlaciones de GTL con la autonomía del grupo y la calidad de la experiencia del grupo. Los resultados revelaron la presencia de una escala unidimensional com un buen nivel de consistencia interna. Los datos sobre la validez nomológica confirmaron las relaciones previstas, habiendo presentado la GTL correlaciones positivas con las variables consideradas. La version portuguesa de la GTL se presenta como una herramienta útil para evaluar el liderazgo transformacional (AU)

The effects on team emotions and team effectiveness of coaching in interprofessional health and social care teams.

The purpose of this study was to examine the effects of coaching behaviours provided by peers and by the leader on the emotions experienced by interprofessional health and social care teams and on members' satisfaction with the team, as well as on team performance. Data were obtained from a survey among 344 employees working in 52 interprofessional health and social care teams from nine Portuguese organizations. The results show that leader coaching and peer coaching have a positive effect on the level of team members' satisfaction with the team and on positive emotions, and a negative effect on negative emotions. Furthermore, coaching provided by peers presents a positive effect on team performance as assessed by the leader of the team. Our findings put forward the importance of engaging in coaching behaviours to promote quality of the team experience, as well as the achievement of team performance objectives. Further studies should explore how coaching behaviours impact the patient, whose well-being is the ultimate objective of a team in the health and social care system, namely in terms of the patient's perception of quality care or patient outcomes.

Effective workgroups: the role of diversity and culture / Grupos de trabajo eficaces: el papel de la diversidad y de la cultura

The purpose of this study was to contribute to the clarification of the conditions under which teams can be successful. To attain this goal, the direct and interactive effects of diversity and of the team’s cultural orientation towards learning on team outcomes (team performance, team members’ satisfaction) were analyzed. Data were obtained from a survey among 73 teams from different industrial and service companies, which perform complex and non-routine tasks. In order to test the hypotheses, multilevel analysis and hierarchical regression analysis were conducted. The results show a significant (although marginal) effect of diversity on members’ satisfaction with the team. The team orientation towards learning presented positive effects on both team performance and members’ satisfaction with the team. No interactive effects were identified. Although the positive impact of a learning culture on organizational effectiveness has already been studied and is well established in the literature, this is one of the first studies that provides empirical evidence of the impact of this kind of culture at the team level. At an intervention level, this study points to managers who want to create successful teams that they may be advised to enhance the levels of the team orientation towards learning, creating conditions in the team to promote and support the acquisition of knowledge (AU)

El objetivo de este estudio ha sido contribuir a aclarar las condiciones que hacen que los equipos sean eficaces. A tal fin se analizaron los efectos interactivos directos e indirectos de la diversidad y de la orientación cultural del equipo sobre el desempeño del mismo (rendimiento, satisfacción de sus miembros). Se obtuvieron datos de una encuesta aplicada a 73 equipos de diferentes empresas industriales y de servicios que llevan a cabo tareas complejas y no rutinarias. Para la puesta a prueba de las hipótesis se llevó a cabo un análisis multinivel y regresión jerárquica. Los resultados señalan un efecto significativo (aunque marginal) de la diversidad en la satisfacción de los miembros en el equipo. La orientación de éste hacia el aprendizaje tenía efectos positivos tanto para el desempeño del equipo como para la satisfacción de los miembros con el equipo. No se observaron efectos interactivos. A pesar de que ya se haya estudiado la repercusión positiva de una cultura de aprendizaje en la eficacia de la organización y que esté bien consolidada en las publicaciones, este estudio es uno de los primeros en aportar pruebas empíricas de las consecuencias de este tipo de cultura al nivel de equipo. Al nivel de intervención, el estudio señala que puede aconsejarse a los directivos que deseen crear equipos eficaces que mejoren el nivel de orientación del equipo hacia el aprendizaje, sentando las condiciones en el equipo que favorezcan y respalden la adquisición de conocimientos (AU)
