A validation study of the leadership styles of a holistic leadership theoretical framework

Abstract

PurposeThe overall purpose of the European Union‐funded Leadership Improvement for Student Achievement (LISA) project was to explore how leadership styles, as conceptualized in the developed dynamic holistic leadership framework, directly or indirectly affect student achievement at the lower secondary level of education in seven European countries. This paper seeks to address this issue.Design/methodology/approachIn its methodological design the study is a mixture of research methods and collaborative action research shared by acting school leaders and researchers. A series of statistical analyses was carried out in order to gather evidence whether the data from the LISA project supported the initially developed holistic leadership theoretical framework. Consequently, first some descriptive statistics are introduced in order to acquaint the reader with the kind of data the survey used from the schoolteacher questionnaires. Further, some explanations are laid out with regard to the methodologies employed in order to analyze the data, such as the treatment of missing data and exploratory and confirmatory factor analysis structural equation models (SEM); then, a description of the main findings is offered through the analyses, which were conducted in order to predict school performance level from the relevant leadership style, followed by between‐countries comparisons and analyses. Finally, an in‐depth discussion and interpretations of the main findings – both integrative and concludive in nature – are offered.FindingsThe quantitative analyses stemming from confirmatory factor analysis and SEM identified five robust underlying dimensions of practised leadership styles across the seven participating European countries. Furthermore, the findings stemming from the logistic regression analyses pointed out clearly the complementary inter‐relationships of the main research questions of the study and analytical strands, especially with regard to the impact of certain intermediate variables on student achievement.Originality/valueThe expected results of this approach are predominantly assumed/seen as an enrichment in the grounding of hypothetical and theoretical ideas as well as professional development for both school principals and researchers. Such an equal contribution of school leaders and school leaders' organizations and researchers could probably provide a model for future professional development programs for both groups of professionals.
