Final regression equation predicting on-task safety errors from demographic and cognitive variables
| Predictors | Std Beta | p-value |
|---|---|---|
| Baseline safety errors | .454 | .000 |
| Secondary Task Performance | −.006 | .959 |
| Age | −.031 | .702 |
| Disease status | .108 | .322 |
| Visual Sensory functioning | −.004 | .963 |
| Speed of processing | −.344 | .016 |
| Memory | .099 | .423 |
| Visuospatial construction | .091 | .390 |
| MT-B (Set shifting) | −.206 | .128 |
The overall F for the regressions were as follows: for baseline safety errors F(9,123) = 5.34, p < .001. When the 6 cases that took on Cook’s D statistics >.035 in the current sample were removed from the regressions above, the substantive inferences were not changed.
