“…In order to determine the number of factors that should be extracted from the initial pool of items, a parallel analysis based on a polychoric matrix of correlations was chosen because it is a robust option to determine the number of factors in scales consisting of ordered polytomous items (Crawford et al, 2010;Holgado-Tello, Chacón-Moscoso, Barbero-García, & Vila-Abad, 2010;Lorenzo-Seva, Timmerman, & Kiers, 2011;. A polychoric correlation matrix of the initial set of items to be responded on a 7-point scale was subjected to an EFA performed with the extraction method of ordinary least squares.…”

In the framework of dual-type theories, decision making is based on two types of information processing: intuitive and rational. Inspired by this framework, our aims were to develop a brief selfrating measurement instrument to assess the affective and rational bases for urgent decision-making under extreme circumstances, and to study its psychometric properties. The samples comprised cadets from a military academy and participants from the general population. The results showed evidence of acceptable reliability as well as structural, convergent, and discriminant validity for the Bases for Urgent Decisions under Extreme Circumstances Inventory (BUDECI), the new 8-item inventory.

“…Sete fatores explicaram um total de 73,10% da variância, excedendo o nível mínimo de 60% para o desenvolvimento de escala (Hinkin, 1998). A análise paralela (Crawford et al, 2010) corroborou a extração de sete fatores. A matriz de correlação dos fatores mostrou correlações acima de 0,30 para os fatores encontrados, implicando que os fatores estão relacionados e são relativamente independentes um do outro (Tabachnick & Fidell, 2007).…”

bResumo O tema da ética nas organizações tem ganhado relevo recentemente. O objetivo deste trabalho foi realizar a adaptação da Escala de Liderança Ética no Trabalho (Kalshoven, Den Hartog, & De Hoogh, 2011). O primeiro estudo apresenta escala traduzida e o teste exploratório da estrutura fatorial com uma amostra de 222 profissionais. Apesar de apresentar 7 fatores (AFE), a estrutura encontrada não correspondente ao modelo original. No estudo 2 (amostra de 3804 profissionais), o ajuste do modelo com estrutura fatorial original da escala foi testado (AFC) e apresentou melhor ajuste que os demais. Para mensurar a validade de construto, a relação da liderança ética com a satisfação com o líder e a supervisão abusiva foi testada. O padrão de relação esperado foi confirmado, sendo encontrada relação positiva com satisfação e negativa com supervisão abusiva. Juntos, os resultados sugerem que a ELET apresenta evidências de validade de construto e boas propriedades psicométricas. Ethical Leadership at Work Scale: validity evidence for the Brazilian version AbstractEthical issues have been a growing concern to organizations. The main goal of this study was to develop a Brazilian version of the Ethical Leadership at Work Scale (Kalshoven, Den Hartog, & De Hoogh, 2011). The first study presents the translated measure and an exploratory study of the factor structure with a sample of 222 employees. Even though the best solution had 7 factors (EFA), the solution found did not correspond to the originally proposed one. In study 2 (sample of 3,804 employees), the goodness of fit of the original factor structure was assessed (CFA). The originally proposed model presented the best fit. In order to assess construct validity, the relationship of ethical leadership with satisfaction with the leader and abusive supervision was measured. Findings confirmed the hypothesized positive relation with satisfaction with the leader and a negative one with abusive supervision. Overall, findings suggest the scale presents good psychometric properties and construct validity.

“…The results of both the Exploratory Graphical Analysis (EGA) and the Confi rmatory Factor Analysis (CFA) pointed to the appropriateness of a three-dimensional model. The contradictory result of the parallel analysis, which indicated the extraction of only two dimensions, can be explained by this method's limitations: It tends to minimize the number of dimensions of models with high correlations between factors and a small number of items per factor (Crawford et al, 2010;Golino & Epskamp, 2017;Ruscio & Roche, 2012).…”

“…EGA is a recently developed technique that uses network analysis coupled with algorithms to detect factors subjacent to the data. This technique is more accurate than parallel analysis for estimating the true number of factors, especially for structures with high correlations between factors and a small number of items per factor (Crawford et al, 2010;Golino & Epskamp, 2017;Ruscio & Roche, 2012).…”

Social support can be defi ned as the perception that there are people who provide individuals with emotional or even fi nancial resources. Perceived social support relates to the perception that support is available if the individual needs it. The present study's aim was to discover, within the Brazilian context, preliminary validity evidence as to the scores of the Multidimensional Scale of Perceived Social Support. The survey involved 831 workers of both sexes, who answered the preliminary version of the scale's questionnaire, containing 12 items. Factor analysis demonstrated that the Brazilian version preserved the original instrument's items and factors (family, friends and signifi cant others). Multigroup analysis demonstrated confi gural, metric and scalar invariance between groups classifi ed by sex and occupational category (professionals in the areas of exact sciences and humanities). The data we obtained in the present study led us to the conclusion that the scale is an instrument with evidence of internal structure validity, thus permitting its use in future research.Keywords: Social networks, scaling, statistical validity. Propriedades Psicométricas da Escala Multidimensional de Suporte Social PercebidoResumo O suporte social pode ser defi nido como a percepção de que existem pessoas que proporcionam ao indivíduo recursos afetivos ou, até mesmo, fi nanceiros. O suporte social percebido relaciona-se à percepção de que o suporte encontra-se disponível, caso o indivíduo dele necessite. O objetivo desta pesquisa é buscar evidências iniciais de validade dos escores da Escala Multidimensional de Suporte Social Percebido, no contexto brasileiro. Participaram do estudo 831 trabalhadores, de ambos os sexos, que responderam à versão inicial da escala, contendo 12 itens. As análises fatoriais evidenciaram que a versão brasileira manteve os itens e os fatores do instrumento original (família, amigos e outros signifi cantes).As análises multigrupos atestaram a invariância confi gural, métrica e escalar entre os grupos divididos quanto ao gênero e à categoria ocupacional (profi ssionais das áreas exatas e humanas). Os dados obtidos na presente pesquisa permitiram a conclusão de que a escala é um instrumento com evidências de validade de estrutura, o que possibilita seu uso em situações futuras de pesquisa.
