Interestingly, the members of the control group experienced
a decline in score after the 2-week period. Several
possible explanations exist for this finding. One possibility
is the tool itself. Variability in body positioning could have
led to differences in the observed assessments, although the
likelihood that all posttest observations of body positioning
resulted in lower scores is unlikely. A more likely possibility
is that the investigators evaluated the participants more critically,
perhaps because of greater familiarity with the test
items or familiarity with some of the observations made in
different cells.
