Hypothesis 1: A reliable Citizenship Performance scale, reflecting a single latent factor, will have
a similar pattern of correlations with FFM personality measures to those observed in previous
research.
A valid measure should also have stronger correlations with measures to which it is
conceptually linked and weaker correlations with measures that are conceptually linked
to independent constructs. As described above, Citizenship Performance has been
conceived of as reflecting motivation and effort, while ability factors, including
cognitive ability and job knowledge, should not have a close relationship with
Citizenship Performance, instead having a direct effect on Task Performance
(Motowidlo, Borman, & Schmit, 1997). So, a valid measure of Citizenship Performance
should have a comparatively lower correlation with a measure of job knowledge than
with a measure of effort.
Hypothesis 2: A reliable Citizenship Performance scale, reflecting a single latent factor, will be
more strongly correlated with a measure of effort than with a measure of job knowledge.
