Abstract: The aim of this research is to analyze and relate the leadership behaviors and communication styles required of Infantry junior officers in their daily command tasks, in order to influence their subordinates to achieve extraordinary effort, group effectiveness and satisfaction. For this study, was used quantitative method and a survey was implemented comprising three questionnaires: one on leadership competences, one on communication styles, and one on with three criterion factors (extraordinary effort, group effectiveness and satisfaction). The survey was administered to a sample of 804 soldiers (30 Junior Officers, 81 Sergeants and 693 privates and corporals). The analysis of the data revealed that subordinates perceive that their commanders (junior officers) practice task oriented leadership behaviors, particularly on "orientation to the mission" and "decision making". The behaviors exhibited by the officers strongly and positively relate with the "assertive" communication style. Moreover, all leadership behaviors practiced by the officers are strongly associated to the criterion factors, with the exception of the leadership dimension "vision", which presents weaker correlations. The leadership dimensions that junior officers can conduct to promote satisfaction is "conflict management" and "participative leadership". ; info:eu-repo/semantics/publishedVersion

Public Service Motivation (PSM) has been shown to be a consistent model in the various studies in which it was used. This study aims to contribute to the validation of PSM, conceptualized by Perry and Wise (1990), within the Portuguese context. Starting from the dimensions that make up PSM in the model proposed by Perry (1996), we intend to identify the dimensions with possible relevance to the Portuguese context. This research inserts itself into the context of a large project of validation of the PSM model representative of the Portuguese Public Administration. Using a questionnaire initially proposed by Perry (1996) which covers forty items to measure the six dimensions, we performed different Exploratory Factor Analyses (EFA) through the elimination of the items that presented a factor loading of below 0,50 and/or saturated with a factor loading greater than 0,50, in more than one extracted factor. Following this, by using the Confirmatory Factor Analysis (CFA), we compared the measurement model achieved (EFA) with the two other models. One was that initially proposed by Perry (1996) and the other was the final model discovered in this study by Perry (1996). The results obtained allowed the identification of three dimensions of the six proposed initially by Perry (1996) and two new dimensions which assume a reverse nature. They are Social Selfishness and Social Cynicism, there not being, however, any literature found to contextualize them within the scope of PSM. The implications of these results were also discussed and future studies suggested.

A Motivação para o Serviço Público (PSM) tem revelado ser um constructo consistente nos diversos estudos em que tem sido utilizado. O presente estudo tem como objetivo contribuir para a validação para o contexto português do Modelo de Motivação para o Serviço Público (Public Service Motivations – PSM) conceptualizado por Perry e Wise (1990). Pretende-se, partindo das dimensões constituintes deste modelo identificar dimensões relevantes para o contexto público português. Insere-se, assim, no contexto de um projeto mais vasto de identificação e validação de um modelo da PSM representativo da Administração Pública Portuguesa. Partindo-se do questionário inicialmente proposto por Perry (1996), constituído por quarenta itens que medem as seis dimensões, foram realizadas diversas Análises Fatoriais Exploratórias (AFE) através da eliminação dos itens que apresentaram um factor loading inferior a 0,50 e/ou saturaram com factor loading superiores a 0,50 em mais do que um fator extraído. Em seguida, através de Análises Fatoriais Confirmatórias (AFC), o modelo resultante da AFE, foi comparado com outros dois modelos. Um foi o modelo inicial proposto por Perry (1996) e o outro foi o modelo final encontrado neste estudo (Perry, 1996). Os resultados obtidos permitiram identificar três dimensões das seis propostas inicialmente por Perry (1996) e duas novas dimensões que assumem uma natureza reverse. São elas o Egoísmo Social e o Cinismo Social, não tendo, no entanto, sido encontrada literatura que as contextualizassem no âmbito da PSM. Foram também discutidas as implicações destes resultados e sugeridos estudos futuros.
