| Study characteristics |
| Methods |
Cluster‐randomised trial, the Netherlands |
| Participants |
300 professional caregivers in homes for elderly persons |
| Interventions |
1) Experimental: emotion‐oriented care training, clinical lessons and supervision meetings: 1‐hour clinical lesson, 6‐day training programme with 4 days at a 2‐week interval and last 2 days at a 4‐week interval. The participants were taught about the dementia syndrome and various care models for communicating with elderly people with dementia (e.g. reality orientation, validation and reminiscence), inequality of the resident‐caregiver relation, understanding the residents' perception of the environment and the attitude and (non‐)verbal communication of staff towards the resident. Intervention homes also received 3 half‐day supervision meetings to support the implementation of emotion‐oriented care.
2) Control: no intervention |
| Outcomes |
MBI, Job satisfaction |
| Identification |
Not able to include in analysis due to missing data. |

Authors' judgement |
Support for judgement |
| Random sequence generation (selection bias) |
Unclear risk |
Quote: "Randomization was performed on the level of homes. ...within each pair, one home was randomly assigned to the intervention or control group, and the home was assigned to the alternate state." (p. S51) |
| 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 |
Low risk |
Quote: "Missing values on items that were part of a scale or subscale were replaced according to the "mean value of valid subtests" principle (i.e. replacement by the mean value calculated from the valid item scores of the [sub‐] scale obtained for the same subject at the same time point). This replacement strategy was only used if less than 25% of the items of a scale or subscale had missing values." (p. S52) |
| Selective reporting (reporting bias) |
Low risk |
All outcomes reported |
| Other bias |
Low risk |
We did not find any indications of other sources of bias |
