Estudos de Psicologia, 21(4), outubro a dezembro de 2016, 435-445 Resumo O engajamento no trabalho consiste em um estado motivacional positivo manifesto em sentimentos de vigor, absorção e dedicação ao trabalho. Para avaliá-lo, foi desenvolvida a Escala de Engajamento no Trabalho de Utrecht. O presente trabalho reuniu evidências de validade da versão reduzida da escala (UWES-9) por meio de análises de estrutura interna, de invariância por gênero e setor de trabalho (público ou privado), e de relações com variáveis externas. A amostra foi composta por 2.897 trabalhadores de ambos os sexos (57,3% do sexo feminino), com média de idade de 32,8. Os modelos indicaram que a estrutura unidimensional obteve melhor ajuste e que os parâmetros dos itens não foram significativamente enviesados pelo sexo, setor e tempo de trabalho. A escala apresentou correlações positivas fortes com sentimentos positivos associados ao trabalho. As propriedades psicométricas do instrumento recomendam seu uso futuro em investigações destinadas a avaliar o engajamento no trabalho em amostras brasileiras.Palavras-chave: comportamento organizacional; psicologia positiva; validade estatística. AbstractAdditional validity evidences of UWES-9 in Brazilian samples. Work engagement is a positive motivational state which is expressed in vigor, absorption and dedication feelings toward work. The Utrecht Work Engagement Scale was developed to measure this phenomenon. The present work collected validity evidence for the reduced scale (UWES-9) concerning its internal structure, gender and work sector (public and private) invariance and relationships with external variables. The sample consisted of 2,897 employees from both genders (57.3% were female), mean age equal to 32.8. The models indicated a unidimensional structure fit to the data, and the items parameters were not significantly biased due to gender, work sector, and job tenure. The scale showed positive strong correlations with positive feelings toward work. The psychometric properties of the scale recommend its future adoption in researchers about work engagement in Brazilian samples.

The aim of this study was to identify the relations of job demands (work overload) and job resources (social support and autonomy) with subjective job well-being (job satisfaction, positive affects, negative affects), as well as the moderating role of personal resources (psychological flexibility at work) in such relationships. The sample consisted of 4,867 Brazilian workers, of both sexes, with ages ranging from 18 to 67 years. Structural equation modelling showed that the work overload was negatively associated with job satisfaction (β = -.06; p < .001) and positively with negative affects (β = .24; p < .001); autonomy was positively associated with satisfaction (β = .08; p < .001) and negative affects (β = .08; p < .001); social support was positively associated with satisfaction (β = .17; p < .001) and positive affects (β = .20; p < .001), and negatively with negative affects (β = -.21; p < .001); psychological flexibility moderated the relationships of overload with satisfaction (β = .04; p < .05) and negative affects (β = .08; p < .001); autonomy with positive affects (β = -.06; p < .001) and social support with negative affects (β = .08; p < .001). These results are discussed from perspective of a job demands-resources theory, especially with respect to the relevance of personal resources for the promotion of occupational well-being.

Authentic leadership consists of a pattern of behavior based on positive psychological capacities and on an ethical and moral climate. The study evaluated the internal structure and convergent validity of the Authentic Leadership Inventory. The sample consisted of 548 workers from public and private organizations of both genders, who responded to the initial version of the scale, containing 14 items, distributed among four factors: self-knowledge, relational transparency, internalized moral perspective and balanced processing. The confi rmatory factor analyses showed that the best fi t model was the four fi rst order factors with a second order factor, which fully confi rmed the original scale model. Authentic leadership had positive correlations with transformational leadership, job satisfaction, work engagement, and affective organizational commitment. The evidences of validity obtained recommend the use of instrument in future research situations.

ResumoA prosperidade no trabalho consiste em um estado psicológico compreendido por componentes afetivos (vitalidade) e cognitivos (aprendizagem). O estudo avaliou a validade de estrutura interna, convergente e de consistência interna da Escala de Prosperidade no Trabalho. Participaram 804 trabalhadores, que responderam à versão inicial da escala, contendo 10 itens (5 para vitalidade e 5 para aprendizagem). Nas análises fatoriais confirmatórias, o modelo de melhor ajuste foi o de dois fatores de primeira ordem com um fator de segunda ordem, com a exclusão do item 8, o que confirmou o modelo original da escala. A escala obteve correlações positivas com os afetos positivos no trabalho, as avaliações autorreferentes e o desempenho no trabalho, e negativas, com a exaustão emocional e os afetos negativos dirigidos ao contexto do trabalho. Concluiu-se que a escala é um instrumento com evidências de validade adequadas, o que possibilita seu uso em situações futuras de pesquisa. Psychometric characteristics of the Scale of Thriving at WorkAbstract Thriving at work is a psychological state comprised of affective (vitality) and cognitive (learning) components. The study evaluated the internal structure, convergent validity, and internal consistency of the Scale of Thriving at Work. The participants were 804 workers who responded to the initial version of the scale, containing 10 items (5 for vitality and 5 for learning). In confirmatory factor analysis, the model with best fit had a first order structure with two factors and one second order factor, excluding item 8, which confirmed the scale's original model. The scale was positively correlated with positive affect at work, core self-evaluations, and job performance, and negatively correlated with emotional exhaustion and negative affect at work. It was concluded that the scale is an instrument with sufficient validity evidence, which allows for its use in future research settings. Características psicométricas de la Escala de la Prosperidad en el TrabajoResumen La prosperidad en el trabajo es un estado psicológico formado por componentes afectivos (vitalidad) y cognitivos (aprendizaje). Este estudio evaluó la validez de la estructura interna, convergente y la consistencia interna de la Escala de Prosperidad en el Trabajo. Participaron 804 trabajadores que respondieron a la versión inicial de la escala, con 10 ítems (5 para vitalidad y 5 para aprendizaje). En los análisis factoriales confirmatorios, el modelo de mejor ajuste fue el de dos factores primarios y un factor de segundo orden, con la exclusión del ítem 8, que confirmó el modelo original de la escala. La escala se correlacionó positivamente con los afectos positivos en el trabajo, las evaluaciones auto-referentes y el rendimiento en el trabajo; y negativamente con el agotamiento emocional y los afectos negativos destinados al contexto del trabajo. Se concluyó que la escala es un instrumento con evidencia de validez adecuado, lo que permite su uso en futuras situaciones de investigación.

Purpose: To investigate the relationship between participation in decision making and social support at work with role performance at work, as well as the mediator role of work prosperity and the moderator role of self-efficacy. Originality/value: The study contributes to the enhancement of the monological net of the concept of prosperity at work, by testing a model that includes other rather neglected constructs as antecedents and consequents of prosperity at work, and by analyzing the role of a personal asset in these relationships, based on the demands-resources model (JD-R). Design/methodology/approach: This is an empirical study, with a quantitative approach of correlational nature, that tested seven hypotheses. The data were collected with self-report questionnaires, and analyzed with structural equation modelling. Findings: All hypotheses were corroborated and indicated that: participation in the decision making and social support have a positive impact on prosperity at work; prosperity at work has a mediation role in the relation between these variables and role performance at work; self-efficacy moderates the positive relations of participation at work and social support with prosperity at work, increasing these relations. The study has important implications for the literature in the field, contributing to the application of the model of prosperity at work to Brazilian samples. Organizations may benefit from these findings if the policies that enhance prosperity are implemented in the organizational environment, obtaining competitive advantage.
