Mean supervisor responses to the study measures are
presented in Table 2. For each study measure, a total score
was generated for participants who provided at least one
response. This decision was based on our finding that for
each study measure the univariate statistics for measure
scores on at least one response, at least three responses, and
complete responses were not significantly different. The
mean JAS score indicated that supervisors were very likely
to provide job accommodations for a back-injured worker
(Mean 3.2, SD 0.48). There were no statistically significant
differences among mean JAS scores for the eight case
vignettes, so the regression analyses did not distinguish
