Applying this principle would require data
to be collected from at least three different
domains. This can be achieved by considering
evidence relating to:
1. the objective and subjective antecedents
of the person’s experience of
stress,
2. their self-report of stress, and
3. any changes in their behaviour, physiology
or health status (which might be
correlated with [1] and/or [2]).
The influence of moderating factors, such
as individual and group differences may
also be assessed. Confidence on the validity
of the data thus obtained is supported
by various studies which have shown that
there is good convergence between selfreport
and supervisor- and subordinate-report.
The use of any measure must be
supported by data relating to its reliability
