Psychometric properties of the multifactor leadership questionnaire when used in early-career pharmacists with provisional registration

Background: The Multifactor Leadership Questionnaire (MLQ) is a validated instrument used to explore participants' perceptions of leadership and the Outcomes of leadership, participants' evaluation of and satisfaction with leadership and willingness to put in extra effort. The factor structure of MLQ varies across studies. The aim was to explore the psychometric properties of the MLQ for early-career pharmacists rating their preceptor's leadership.

Methods: The MLQ was administered to provisionally registered pharmacists during the final half of their 1 year of supervised practice. Confirmatory and Exploratory Factor Analysis (CFA & EFA) and Structural Equation Modeling (SEM) were used to analyse the data.

Results: Responses were obtained from 430 participants (25 % of all Australian pre-registration pharmacists at the time). CFA demonstrated that the original 9-factor model and a range of previously published models were poor fit for the data. EFA revealed that a good fit was a model with 4 factors named: Passive laissez-faire, Strategic visionary, Personalized, and Active management by exception. Passive laissez-faire and Active management by exception were consistent with previously published models. The Strategic visionary and Personalized factors were interpreted as 2 forms of transformational leadership that includes the provision of rewards depending on performance. A SEM of MLQ sub-scales predicting Outcomes of leadership explained 90.3 % of variance. Personalized leadership was highly predictive (β = 0.743, P < 0.001) while the three other factors had negligible effects.

Conclusion: The psychometric analyses demonstrated overlap of the original 9-factors. A more parsimonious 4-factor model fit the data well.
