Measurement of Servant Leader ship
In the research, the level at which school principals exhibited servant leader -
ship behaviours was measured using the servant leader ship scale (OLA) developed
by Laub (1999). Six factors of servant leader ship are distinguished (see
above): (1) valuing people (10 items); (2) development of people (9 items); (3)
building community (10 items); (4) displaying authenticity (12 items); (5)
providing leader ship (9 items); and (6) sharing leader ship (10 items).
In this study, respondents were asked to indicate the extent to which they
agreed with the statement using a five-point Likert scale ranging from 1
(strongly disagree) to 5 (strongly agree).
OLA has been validated through a number of servant leader ship research
studies (Herbst, 2003; Drury, 2004; Hebert, 2003; Miears, 2004; Irving 2005).
The adaptation process of the OLA scale to Turkish included translation,
validity and reliability studies. Factor analysis was carried out to find out
whether the factors were coherent with the ones mentioned in the Laub (1999)
scale due to the fact that this study was carried out in an environment with a
different cultural structure. The compliance of the data with the factor analysis
was ascertained with Kaiser–Meyer–Olkin (KMO) and Barlett Sphericity test.
KMO was 0.97 and Barlett Sphericity test (X2 = 30500.180; p = 0.000) was found
to be meaningful. These results indicate that the scale is in compliance with
the factor analysis. Based on these results, the factor analysis was reapplied to
the servant leader ship scale for structure validity and the six factors were determined
in compliance with the OLA. As a result of the factor analysis with
