Propriedades Psicométricas da Escala de Liderança Servidora

Abstract

RESUMO O líder servidor pode ser visto como alguém motivado por um sentimento de servir sua equipe que vai além dos seus próprios interesses. O estudo teve como objetivo adaptar e reunir evidências iniciais de validade de estrutura interna e de relações com outras variáveis da Escala de Liderança Servidora. A amostra foi composta por 432 trabalhadores brasileiros de ambos os sexos (54,6% do sexo masculino). Na verificação da estrutura interna, foram testados três modelos, mediante a análise fatorial confirmatória, sendo que o modelo de oito fatores correlacionados foi o que apresentou os melhores índices de ajuste. A maioria das dimensões de liderança servidora apresentou correlações de moderadas a fortes com a liderança autêntica, com o engajamento laboral, com o comprometimento organizacional afetivo e com a satisfação laboral. As evidências iniciais de validade presentemente obtidas recomendam o uso futuro da escala em investigações brasileiras. Palavras-chave: estilo de liderança; validade estatística; psicometria. ABSTRACT-Psychometric Properties of the Servant Leadership Scale The server leader is seen as someone motivated by a feeling of serving their team that goes beyond their own interests. The aim of the study was to adapt and gather initial evidence of internal structure validity and relationships with other variables for the Servant Leadership Scale. The sample consisted of 432 Brazilian workers of both sexes (54.6% male). In the verification of the internal structure, three models were tested through confirmatory factor analysis, with the model of eight correlated factors being the one that presented the best fit indices. The majority of the dimensions of servant leadership had moderate to strong correlations with authentic leadership, job engagement, affective organizational commitment, and job satisfaction. The initial evidence of validity obtained strengthens the possibility of the future use of the scale in Brazilian investigations.

Development and Validation of the High Performance Volleyball Self-Efficacy Scale

“…The higher the score, the greater the self-perceived self-efficacy of the player. The validated GSE for the Brazilian population (Teixeira and Dias, 2005) presented good psychometric properties (internal consistency α = .81).…”

“…The GSE was translated and adapted into Portuguese from the original form (Schwarzer and Jerusalem, 1995) by Teixeira and Dias (2005). The GSE is a self-report instrument comprising 10 items (e.g., "I can usually face any adversity"), grouped into a single dimension, referring to the general feeling of personal competence to deal effectively in various stressful situations.…”

Queen Bee Phenomenon Scale: Psychometric Evidence in the Brazilian Context

“…In the psychometric sphere, it would be good to have studies replicated with the QBPS, in addition to verifying its convergent validity with other measures, such as the 'servant leadership' (Pereira & Ferreira, 2019) and 'abusive leadership' (Puente-Palacios & Côrtes, 2019) scales. Additionally, analyzing the quality of each item via item response theory (IRT) is proposed to obtain additional information concerning the difficulty and discrimination of each item.…”

mediación de la pasión armoniosa por el trabajo en la relación entre el liderazgo de servicio y las intenciones laborales: Un estudio longitudinal

“…Servant leadership was assessed using the van Dierendonck and Nuijten's (2011) Server Leadership Scale (SLS), validated for the Brazilian context by Pereira and Ferreira (2019). It consists of 28 items, distributed in eight dimensions, to be answered on a six-point Likert scale, ranging from 1 (Never) to 6 (Always).…”
