Research in the area When researching transformational and transactional leadership the most frequently used survey is called “the Multifactor Leadership Questionnaire” (MLQ Form 5X). This is a questionnaire that measures each of the components of the full range of leadership, initially starting with Bass’ (1985) factors and analysis. The original scales in the questionnaire are based on a initial factor analysis and earlier versions. Earlier research on transformational leadership was limited, because the knowledge in this area was too primitive for finding good examples for the items in the questionnaire. Another weakness in the first version of the MLQ related to the wording of items. Most items in the scale of charismatic leadership described the result of leadership, instead of specific actions of the leader that can be observed and that, in turn, lead to the results. In response to the critics, Bass and Avolio (1990) included in the revised and now subsequent versions many more items that describe leadership actions that are observed directly. They also split out attributions of leadership associated with Idealized Influence and behaviors and actions into two separate scales. The current version of the MLQ Form 5X includes 36 items that are broken down into 9 scales with 4 items measuring each scale. Subsequent validation work by John Antonakis and his colleagues provided strong evidence supporting the validity and reliability of the MLQ5X.[3] Indeed, Antonakis et al. (2003) confirmed the viability of the proposed nine-factor model MLQ model, using two very large samples (Study 1: N=3368; Study 2: N=6525). Although other researchers have still been critical of the MLQ model, since 2003 none has been able to provide dis-confirming evidence of the theorized nine-factor model with such large sample sizes at those published
