This study investigated the use of the Occupational Stress Indicator (
OSI) on school administrators in Singapore. The sample of 223 school a
dministrators consisted of the top management group of principals and
vice-principals and the middle management group of heads of department
. The school administrators reported pressure at work, and consequentl
y, higher levels of mental and physical ill health. They had high locu
s of control scores, indicating low internal control over their enviro
nment. However, they also reported greater use of coping strategies an
d higher job satisfaction. Psychometrically, the sub-scales of sources
of pressure, job satisfaction, and mental and physical ill health wer
e found to be reliable. The items of the scales of type A, locus of co
ntrol and coping skills had to be re-factor analysed for the Singapore
an sample. The new factors were found to have higher reliability. When
the stress and job satisfaction levels of the principals/vice-princip
als and heads of department were compared, the heads of department rep
orted significantly less job satisfaction and higher levels of mental
and physical ill health. They perceived less internal control in their
work situation.
