Purpose

This study aims to explore the relationship between transformational leadership and employees’ innovative work behaviour (IWB), additionally examining the mediating effect of psychological empowerment.

Design/methodology/approach

The study is based on a cross-sectional design, data being collected from 139 employees through the following structured questionnaires: Multifactor Leadership Questionnaire, IWB and psychological empowerment instrument.

Findings

The findings revealed a positive and significant relationship between transformational leadership and both IWB and psychological empowerment, as well as the fact that transformational leadership, through psychological empowerment, fosters IWB.

Research limitations/implications

One of the main weaknesses of this study is the use of a cross-sectional design, which does not allow for an assessment of the cause–effect relation. Also, using a self-reported questionnaire might have brought common method bias.

Practical implications

The paper shows that, by creating a greater sense of empowerment, leaders could have a higher positive effect on employee’s levels of IWB. Moreover, empowerment acts as one of the most important and effective processes within the transformational leadership framework in fostering innovation among followers.

Originality/value

This study extends the empirical research on transformational leadership and its influence on employees’ work attitudes. Given the scant research on the role of the psychological empowerment, the results of this study confirm not only its mediating role but also the need for further studies in this direction.

变革型领导和创新工作行为：心理赋权的中介作用

目的

本研究旨在探讨变革型领导与员工创新工作行为（IWB）之间的关系，此外还研究了心理授权的中介作用。

设计/方法/方法

该研究基于横断面设计，通过以下结构化问卷从139名员工中收集数据：多因素领导力问卷，IWB和心理授权工具。

发现

调查结果表明，变革型领导与IWB和心理授权之间存在积极而重要的关系，而且通过心理授权，变革型领导可以促进IWB的发展。

研究局限/意义

该研究的主要弱点之一是使用横截面设计，该设计无法评估因果关系。同样，使用自我报告的调查表可能会带来常见的方法偏见。

实际影响

该文件表明，通过增强授权感，领导者可以对员工的IWB水平产生更高的积极影响。此外，在变革型领导力框架内，赋权是促进追随者创新的最重要和有效的过程之一。

创意/价值

这项研究扩展了关于变革型领导及其对员工工作态度影响的实证研究。鉴于对心理赋权的作用的研究很少，这项研究的结果不仅证实了它的中介作用，而且还证实了在这个方向上进一步研究的必要性。
