3.4 Measures
This research used measures similar to those used in previous studies (e.g. Minsky,
2002; Lee et al., 2001) so results could be compared. This research developed two sets
of survey questionnaire - subordinate and supervisor (See Appendix 1 and Appendix
2). While the subordinate survey had four sections of the questions, the supervisor
survey had two sections of questions. Both survey forms had questions pertaining to
the demographic details of the participants.
3.4.1 Measures in Subordinate Survey
The subordinate survey questionnaire had three measurement scales along with
demographic questions. The measures are explained in the following sections.
3.4.1.1 Subordinate LMX
The employees' perception of the work relationship with their supervisor was analysed
using a seven-item inventory called LMX-7 which was derived from Graen and
Scadura (1984). In particular, Minsky (2002)used the LMX-7 in a doctoral dissertation
to calculate LMX agreement and had an acceptable reliability score (α = .88). The
reliability score is the extent to which similar results could be produced (Anderson,
2009). Each item in the present study was arranged in a 7-point Likert scale format.
Likert scales are psychometric scales commonly used in questionnaire where responses
are measured in commonly spaced intervals (Bryman & Bell, 2003). The measure had
a coefficient α (measure of internal consistency or reliability) of 0.89. All measurement
items included in this scale are presented in Table 1.
