The Global Leadership Life Inventory: development and psychometric properties of a 360-degree feedback instrument

Abstract

The purpose of this paper is to describe the design of Global Leadership Life Inventory (GlobeInvent), a 360-degree leadership feedback instrument. This instrument is presently used in executive programmes to help identify the operational mode of individual executives. Proper use of this instrument enables the user to determinate those areas of leadership behaviour where improvement is needed. Because most studies pay attention only to the surface manifestations of leadership, most leadership feedback instruments, in turn, are not concerned with the psychodynamic processes that underlie leaders' character and behaviour. To address this gap, the GlobeInvent is based on a clinical orientation to the study of leadership. This approach provides a more complete analysis of the ‘inner theatre’ of leaders – that is, what makes them tick – as well as measuring the dynamic, two-way relationship between leaders and followers. The first step in designing the instrument was to pinpoint significant themes pertaining to exemplary leadership. To that end, semi-structured interviews with senior executives were held. The leadership dimensions that emerged from that process were then tested on an international sample of senior executives. Analysis of the data from the testing confirmed the existence of twelve robust dimensions with a high reliability and internal consistency. Because the GlobeInvent is a 360-degree feedback instrument, this article addresses differences between ‘Self’ scores and scores given by others (‘Observers’), gender differences in scoring and the influence of nationality, management experience and age on test results. The implications of using such an instrument as a 360-degree feedback tool are reviewed, and suggestions for future research are offered.
