With the objective of answering the question “Does leadership change in the lifelong learning world?” the present study examines the validity and reliability of an instrument (a structural equation model) designed for measuring factors that have an impact on lifelong learning and leadership issues. Specifically, it evaluates construct validity by estimating both convergent and discriminate validity, while evaluating the internal consistency of the instrument itself. Another aim of the study is to estimate how the instrument determines the reasonable relations among the factors, describes the reasonable results and assigns the quality of data adaptation within it. A 23-item questionnaire referring to five factors (time management, change management, diversity management, conflict management, and innovative skills) was distributed to a sample of 134 graduate students from the Educational and Social Policy Department of Macedonia University. This questionnaire with confirmed validity and reliability was used as a basis for the design and evaluation of the structural equation model. In order to examine the structure of the factors measured with this questionnaire, a confirmatory factor analysis with models of structural equations and the development of a model indicating the relationship between the various factors was attempted, and in particular the relationship between the observed variable and the factors was evaluated. The aim of this confirmatory analysis was to reveal if the questionnaire is actually valid and suitable for the measurement of the variables it investigates. It is noted that an instrument of evaluation has validity if the existence of variation is justified in its statements. In order to test this model its suitability must be assessed.
