| Notes | ||
| Risk of bias | ||
| Bias | Authors' judgement | Support for judgement |
| Random sequence generation (selection bias) | Unclear risk | Paper stated, "participants were randomly assigned to one of three groups," but did not report method used. |
| Allocation concealment (selection bias) | Unclear risk | Not specified. |
| Blinding of outcome assessment (detection bias) All outcomes | Low risk | Assessments made by an independent psychologist, and staff who knew the residents well, but were not involved with the therapy groups. |
| Incomplete outcome data (attrition bias) All outcomes | Low risk | n/a. |
| Selective reporting (reporting bias) | Low risk | All outcomes listed in the methods section were reported and there was no evidence of selective outcome reporting. |
| Other bias | Low risk | n/a. |
| Availability of training and supervision Objective outcome measures | Low risk | Paper reported, "preliminary training for staff included six hours of introductory talks, videos, discussions and hand outs." Staff training was carried out by a clinical psychologist. |
| Availability of manual or protocol for intervention All outcomes | Low risk | Paper reported, "the reminiscence therapy sessions were based on the format suggested by Andrew Norris (Norris 1986)." |
