Lim, T. K. (1994, November/December). Factorial validity of the occupational stress indicator. Paper presented at the Australian Association for Research in Education Conference, New South Wales, Australia.
This study investigated the use of the Occupational Stress
Indicator (OSI) on school administrators (principals, vice
principals and heads of department) in Singapore, focusing on the
reliability and factorial structure of the OSI. Generally,
school administrators had fairly high scores on Sources of
Pressure at work and consequently high levels of Mental and
Physical ill health. In examining the factors of the six scales
of the OSI, psychometrically the factors of three scales, Sources
of Pressure, Job Satisfaction, Mental and Physical Health were
found to be quite reliable. Some factors of the three other
scales, Type A, Locus of Control and Coping Skills were found to
be less reliable. After the items of these scales were re-factor
analyzed, the new factors were found to have higher reliability.
For comparative purposes within the sample, the factors of the
OSI scales were analyzed by gender and marital status. The males
found more job satisfaction, in design and structure, in
organisational processes and in personal relationships. The
females used social support as a coping skill more than the
males. Surprisingly, there were no significant differences in
job stress between the single and married administrators, except
for the interface between home and work.
