Instrumento de avaliação das competências de liderança nas chefias de enfermagem: Estudo das propriedades psicométricas

Abstract

Introduction: Leadership skills are seen as essential tools for the success of organizations in general and their employees, in particular. Thus, it becomes crucial to have instruments which provide the measurement of the mentioned skills. Objective: This article aims to evaluate the psychometric properties of the leadership skills questionnaire developed by Robert Quinn. Methods: In this crosssectional study, 248 nurses were included who work in Centro Hospitalar do Porto, evaluating the leadership skills of nursing managers. The validity and reliability of the instrument of study were estimated using a descriptive, correlation, confirmatory factor and internal consistency analysis. Results: The questionnaire of leadership skills has a good discriminative power, as the correlations between items and dimensions (leadership roles) are moderate to high, with higher values for the factor where they conceptually belong. The correlations of the items with the dimensions, without any overlaps, show moderate values, mostly higher than 0.60, which indicates relative interdependency between dimensions. This fact confirms a representative factor structure of a construct which agrees with the conceptual model that originated it. The values of internal consistency (Cronbach's alpha), for all leadership roles, fluctuate between 0.86 and 0.94. Discussion and Conclusions: Like other reference studies, this study revealed that the questionnaire analysis has good psychometric properties and could be a suitable instrument to evaluate the perception of leadership skills in the study population.
