Authors' judgement |
Support for judgement |
| Random sequence generation (selection bias) |
High risk |
"Nurses and nurse aides were recruited from long‐term and complex continuing care units in a large urban geriatric teaching hospital and randomly assigned to intervention or wait‐list control groups. Because the study was conducted during the summer, however, several exceptions were made to accommodate participants' vacation schedules and additional control participants were recruited." (p. 106) |
| Allocation concealment (selection bias) |
Unclear risk |
Not reported. |
| Blinding of participants and personnel (performance bias)
All outcomes |
High risk |
Participants not blinded. |
| Blinding of outcome assessment (detection bias)
All outcomes |
High risk |
Participants were not blinded whereas outcomes are self‐reported. |
| Incomplete outcome data (attrition bias)
All outcomes |
Unclear risk |
It is unclear if any participants dropped out. |
| Selective reporting (reporting bias) |
Low risk |
All outcomes reported |
| Other bias |
Low risk |
We did not find any indications of other sources of bias. |
