RESUMEN

This paper investigates the effects of transformational leadership on team effectiveness. In particular, we studied the effects of transformational leadership on three criteria of team effectiveness: viability, team process improvement, and quality of group experience. In addition, we examined the indirect effect of transformational leadership on team effectiveness via affective team commitment. Ninety teams working in different organizational contexts in Portugal were surveyed. Two different questionnaires were administrated, respectively, to team members and team leaders. Team members (N = 445) were surveyed about leadership, team commitment, and quality of the group experience, whereas team leaders (N = 90) were asked to assess team viability and team process improvement. Hypotheses were tested through structural equation modelling. Results revealed that affective team commitment partially mediates the relationship between transformational leadership and quality of the group experience. The mediational role of affective team commitment between transformational leadership and both team viability and team process improvement was not supported. Implications for practice and suggestions for further research are provided


El objetivo de esta investigación fue contribuir a aclarar los efectos del liderazgo transformacional en la eficacia de los equipos. Hemos estudiado los efectos directos e indirectos del liderazgo transformacional en tres criterios de eficacia del equipo: la viabilidad, la mejora del proceso en equipo y la calidad de la experiencia grupal. Además, analizamos el efecto indirecto del liderazgo transformacional en la eficacia grupal a través del compromiso afectivo con el equipo. Se encuestó a 90 equipos que trabajaban en diferentes contextos organizacionales en Portugal. Se administraron dos cuestionarios diferentes respectivamente a los miembros del equipo y a los líderes. Los miembros del equipo (N = 445) fueron encuestados sobre el liderazgo, el compromiso con el equipo y la calidad de la experiencia grupal, mientras que a los líderes (N = 90) se les pidió que evaluasen la viabilidad del equipo y la mejora del proceso en equipo. Las hipótesis se examinaron mediante modelos de ecuaciones estructurales. Los resultados revelaron que el compromiso afectivo con el equipo media parcialmente la relación entre el liderazgo transformacional y la calidad de la experiencia grupal. El rol de mediación del compromiso afectivo del equipo entre el liderazgo transformacional, la viabilidad de éste y la mejora del proceso en equipo, no ha sido sustentado empíricamente. Además, presentamos implicaciones para la práctica y sugerencias para futuras investigaciones

RESUMEN

The purpose of this study was to clarify the role of team resilience on different facets of effectiveness (team viability and quality of the group experience). Moreover, given the importance of team resilience for the organizational context, it was also our aim to contribute to the study of the conditions that promote team resilience, analyzing the role of transformational leadership. Finally, we examined whether the relationship between transformational leadership and team resilience stimulates positive team outcomes. Ninety teams (445 employees from 40 companies) were surveyed and path analysis was used in the test of the hypotheses. The results showed a positive direct effect of team resilience on both team viability and the quality of the group experience. Moreover, a positive relationship was also identified between transformational leadership and team resilience. Finally, support was found for the mediated effect of team resilience on the relationship between transformational leadership and the dimensions of team effectiveness considered. The findings of this study highlight the role of team resilience as an intervening process between transformational leadership and team effectiveness. Supervisors should promote team resilience, adopting transformational leadership behaviors, in order to contribute to increase team viability and the quality of the group experience.

RESUMEN

O objetivo deste estudo foi analisar o papel mediador dos comportamentos de suporte na relação entre a liderança transformacional e quatro critérios da eficácia da equipe (designadamente, o desempenho, a viabilidade, a qualidade da experiência grupal e os processos de melhoria). Conduziu-se um estudo empírico com uma amostra composta por 653 participantes de 117 equipes de diferentes setores de atividade (e.g., indústria, proteção civil, consultoria), onde foram testadas as relações previstas. Os resultados mostraram um efeito direto positivo da liderança transformacional nos comportamentos de suporte, assim como dos comportamentos de suporte na eficácia da equipe (nomeadamente, no desempenho, na viabilidade, na qualidade da experiência grupal e nos processos de melhoria). Além disso, foi igualmente identificado um efeito mediador dos comportamentos de suporte na relação entre a liderança transformacional e os quatro critérios da eficácia da equipe. Implicações para a investigação, para a prática profissional e pistas para futuras pesquisas foram apresentadas.


The aim of the present study was to analyse the mediator role of supportive behaviours in the relationship between transformational leadership and four team effectiveness criteria: performance, viability, quality of group experience, and improvement processes. An empirical study was conducted with a sample of 653 participants from 117 teams from different professional practice sectors (e.g., industry, civil protection, and consultancy), in which these relationships were tested. The results showed a positive direct effect of transformational leadership on supportive behaviours and on team effectiveness (including performance, viability, quality of the group experience, and improvement process). Furthermore, the present study also identified the mediator effect of supportive behaviours on the relationship between transformational leadership and the four team effectiveness criteria considered. Implications for research and professional practice were discussed, and suggestions for further studies were offered.

RESUMEN

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)

RESUMEN

This paper examines team learning behaviors within a nonlinear dynamical system (NDS) perspective. The present research is based on a sample of 36 project workgroups, where data were collected at two moments of their life cycle, with visual analogue scales. Using both the least squares method and maximum likelihood, it proposes a cusp catastrophe model for explaining team learning. The cusp model is superior to its linear alternatives and implements team culture as the asymmetry variable and team potency as bifurcation. The findings of cusp structure in the data support the existence of discontinuous shifts in learning behavior and furthermore a proposition that the punctuated equilibrium model (PEM) might be a reasonable model for describing group functioning, since it encompasses such sudden changes between distinct stages (attractors). A discussion on small group research is also provided by highlighting the nonlinear dynamics of team processes, along with further implications for research and practice.

RESUMEN

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.

RESUMEN

Primary breast sarcoma, arising from connective tissue within the breast, is extremely rare, accounting for less than 1% of all primary breast malignancies and no more than 5% of all sarcomas. The rarity of this pathology limits most studies to case reports and small retrospective studies, which has led to a lack of consensus on the clinical management. We report a clinical case of a 52-year-old woman, perimenopausal, previously healthy, with regular breast surveillance, who presented with a large (>20 cm) and rapidly expanding hypervascularized tumor of the left breast developed over 10 days, with a very thin preulcerative skin over the last 4 days. There was no systemic dissemination. The patient was submitted to total mastectomy and excision of axillary adenopathy. The tumor was diagnosed histologically as malignant phyllodes tumor associated with areas of high-grade sarcoma. Due to rapid growth and aggressive histological characteristics, adjuvant chemotherapy and radiotherapy were performed. There is a lot of evidence that tumors larger than 5 cm are associated with a poor prognosis. Despite the poor prognosis associated with this aggressive entity, the patient had no recurrence during 5 years of follow-up. We review the relevant literature about primary breast sarcomas.

RESUMEN

A presença de fantoches em dispositivos psicoterapêuticos existe há quase um século, e podemos dizer que hoje está entre as mediações frequentemente utilizadas no tratamento de crianças, bem como de adultos. Neste artigo, vamos nos concentrar no campo da psicopatologia clínica e no lugar que pode ser atribuído ao fantoche no encontro com as questões que atravessam a prática de um hospital-dia para crianças de um Centro Médico-psicológico (CMP).


The presence of puppets in psychotherapeutic devices exists for nearly a century, and we can say that today they are among the mediations often used in treating children and adults. In this article we focus on the field of clinical psychopathology and on the place that may be attributed to the puppet in the encounter with issues that cross the practice of a day hospital for children of a Medical Psychology Center (CMP).

RESUMEN

A experiência do trabalho terapêutico familiar enfatiza a influência do sofrimento traumático nas relações pai-filho, especialmente quando estas se constituem sobre os modos de filiação narcisistas em que predomina o que se incorpora por violências transgeracionais e transubjetivas. A abordagem da terapia familiar é hoje bem reconhecida no tratamento de crianças e adolescentes e, apesar de sua difícil aplicação, é muito promissora para famílias que lidam com jovens adultos atraídos pelas lógicas de ruptura (violência, isolamento social, vícios), fornecendo meios para desenvolver dispositivos de trabalho clínico plurifocais apoiados em uma rede interinstitucional.(AU)


The experience of family therapy work emphasizes the influence of traumatic suffering in parent-child relationships, especially when they are constituted over the narcissistic membership modes motivated by the predominance of what is incorporated and by transgenerational and transsubjetive violence (shame, uprooting, cultural violence). The approach of family therapy is currently well recognized in the treatment of children and adolescents, and despite its difficult application, it is very promising, being focused on families dealing with young adults attracted by the rupture logics (violence, social isolation, addictions), providing means to develop multifocal clinical work devices supported by an inter-institutional network.(AU)


En la experiencia de trabajo terapéutico familiar se destaca la influencia del sufrimiento traumático en las relaciones entre padre-hijo, sobre todo cuando están constituidas por los modos de afiliación narcisistas motivados por la predominación a lo que se incorpora y por las violencias transgeneracionales y transubjetivas (la vergüenza, el desarraigo, las violencias culturales). El enfoque en la terapia familiar es más aceptado actualmente para el tratamiento de niños y adolescentes y, a pesar de su difícil aplicación, es promisorio por destinarse a familias que tratan de jóvenes adultos atraídos por la ruptura de la lógica (la violencia, el aislamiento social, las adicciones), así proporciona medios para el desarrollo de dispositivos de trabajo clínico plurifocales que se apoyan en una red interinstitucional.(AU)
