| Study characteristics |
| Methods |
RCT, UK |
| Participants |
20 forensic mental health nurses |
| Interventions |
1) Experimental: psychosocial Intervention Training: 20 days of training with the aim to improve nurses' knowledge about serious mental illness and attitude towards patients and thus decrease subjective burnout. Training duration 6 months. The training helps clinicians to conceptualise their patients' problems within a more empathic framework and trains them in the skills to intervene effectively. Thus, self‐efficacy may increase and jobs may be perceived as more rewarding.
2) Control: no intervention |

Authors' judgement |
Support for judgement |
| Random sequence generation (selection bias) |
Unclear risk |
"The 20 staff who volunteered for the PSI training were randomly allocated to either the experimental PSI training group (n = 10) or a waiting list control group (n=10). The sample was stratified by ward, sex and day/night duty, thus subjects in each group represented all grades of staff and all wards." (p. 473) |
| Allocation concealment (selection bias) |
Unclear risk |
Not reported. |
| Blinding of participants and personnel (performance bias)
All outcomes |
High risk |
Participants were 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 |
Presumably all participants completed all measurements as no data reported on dropouts. |
| Selective reporting (reporting bias) |
Low risk |
All outcomes reported. |
| Other bias |
Unclear risk |
We did not find any indications of other sources of bias. |
